Guys,

 

I needs some advice, I bought a Raby powered speedster in PA. It was on EBay.  It isn't running very smooth, and I am not sure it has been driven much in the last couple of years.  I asked the PO about adjusting the valves.  He said that it isn't necessary unless they make noise, and the valve lash is o.o.  My understanding is a VW engine should have its valves adjusted every 3k miles, but I know a Raby engine is unique. Any recommendations.  Also, what grade oil should I use? The PO suggested a synthetic oil, 5w-40.  I am cleaning the air filters and changing out the spark plugs.  I am also thinking of spraying some carb cleaner in the Webers.  The air filters were Black.  Any and all help is appreciated....I look forward to improving this car. I have the speedster fever!

Bill, where in PA are you? Is it a type1 or type4?

 

Yes, valve lash should be checked once a year or every 3000. Most probably chromoly steel pushrods, which get adjusted to loose zero clearance.

 

I would just us regular dino oil, you should change it once a year or more(if higher mileage). Why waste the money? Jake recommends 20W50 for summer but it NEEDS to have ZDDP in it, not modern oils designed for modern engines. You need an oil designed for flat-tappet engines.

 

If the air filters are really black and cruddy, clean them. But most people don't realize that a K&N type filter actually filters BETTER when there is a bit of dirt in it.

 

Webers aren't all that hard. How far are you from the NY border? I'm OK with carbs, they talk to me. As long as the fuel supply is fresh and clean(new filter?), they aren't that hard.

Thanks Everyone for your welcome advice.  Jack I know you have a Raby Type IV, so I don't think I can do better then using what oil is recommended by the builder.  I am going to pull the valve covers and do an oil change next weekend.

 

This weekend, I will be putting the floor carpets, door panels, and driver seat belt back in.  The car really got wet inside when I trailered it from PA to Bedford, NH.

 

Jake recommends Brad Penn Partial synthetic High Performance Oil, "The green oil".

 

Summer, 20 W50 

Winter,  10 W40

 

I believe that there are two types of Brad Penn.  The p/n for the 20 W50 is 009-7119

Brad penn comes in several weights. The "racing oil" is there signature partial syn blend. I stock it in straight weights 30, 40, 50, & nitro 70. Multi weights are 0-30, 5-30, 10-30,10-40,15-40,20-50. The break in oil comes 30wt.  they also have a traditional gear lube and several diesel oils. We also stock there blends for the newer cars in 5-30 and 0-30. Great products!!!

Thanks guys, I got the carpets back in changed the pedal covers to basic EMPI. cleaned up the rusted racing belts. Changed the plugs. (Shocked to find out half my Bosch Platinum's were made in India.). Cleaned the sponge for the crankase ventilator. Cleaned and oiled K&N's, and sprayed some carb cleaner in the Carb's.  I also topped it off with premium gas. It appears to be running better, still early, but better. I love the sound and the torque. Really fun to drive. I will reach out to Dr. Clock. I know he is the east coast speedster authority, and it sounds like he has first hand knowledge of my car.  Life is good!

Bill - Platinum plugs have only a thin coating of platinum - they shouldn't be cleaned or really gapped (as it scratches off the coating).  Suspect 1 or 2 here might run them but the proper heat range regular plug (Bosch, Champion, NGK) is probably a better bet. Part of tune up should be valve adjustment and timing adjustment.  I like a bottle of Chevron Techron added to gas to clean fuel passages/carb - it removes deposits.  

 

I'd look at all rubber fuel line - but if recently done by Alan (in last 5 years) they may just need visual inspection (fire in a fiberglass car is not good at all).  Avoid the often added 59 cent clear plastic fuel filter in engine compartment. Have a good size fire extinguished mounted inside car where you can easily reach it. 

Robert, 

 

There are multiple problems with the plastic in line fuel filter in the engine compartment: 1) metal is considered a safer medium to contain the filter as opposed to plastic--more heat and abrasion resistance.  Hence, NHRA rules mandate metal fuel filters; 2) placement should be outside the engine compartment to minimize the fire risk in case of filter failure; 3) any fuel filter should be supported to minimize movement; and 4) the failure of a filter mounted before the fuel pump will be less likely to cause a fire than failure of a filter that is under pressure from the fuel pump.

 

You can't deny the convenience of being able to assess the fuel quality by looking at the fuel in a plastic fuel filter.  However, their use raises several safety concerns that more than compensate for their removal.  Do it once, do it right.

Guys, you're over-thinking this. Go buy a metal one at any farm supply store or your FLAPS. It'll be $3, tops. Change it once a year. Be happy.

Thanks Stan!  I also was going to comment that everyone is over thinking this. As long as the fuel lines are secure with hose clamps I have used the plastic or metal ones for years. Those glass ones I found to leak after opening them to clean and today's fuel and additives cause havoc with the seals.

 Bill,

I haven't see that car for 10 plus years, I am sure it needs a good service and mechanical inspection.

You bought a "Go Cart" on steroids... That thing is an absolute blast to drive, Roger had way more  than $35k into it.

The Raby type 4 Motor and trans is worth what you paid for the entire car...What a screaming deal!

You want a really good fuel filter (10 micron) that is easily found and won't break the bank (or wallet)??

 

Napa Gold 3031

 

All metal

 

10-micron screening (about 1,000 times better than the original VW screen (the filtering capabilities of those measured in pebbles).

 

Available at Any NAPA store

 

Mount it with a big, metal cable clamp (Home Depot electrical dept.) to help you secure it (see above posts) so it won't move or vibrate.

 

Comes with bubble-flared ends to allow easy attachment with rubber fuel hoses before the fuel pump, AND it has a 1/4" inlet and outlet.

 

It's the right size to easily fit on the shelf just ahead of the passenger's footwell and close to your rotary, electric fuel pump.  What?  You use a mechanical pump on the engine?  Well, it works just fine with those, too.

 

And the cost?   $4.29 USD each.

 

Replace it ever 2-3 years (actually, I do mine every 5 years, but I'm notoriously lazy).

One thing I've never seen mentioned on the forum in any thread referencing engine fires:  Make sure you have some way to operate your hood latch in an emergency.  I'm an old retired firefighter, and could't even guess how many car fires I've extinguished.  One thing that invariably happens is that the hood release cable melts down and you can't get the hood open.  We would come off the engine with a Haligan Tool in hand so we could pry up a corner or two of the hood to get the hose stream inside (Of course that don't much help on an old Beetle motor either.).  Also, once you pop that hood, don't stand back 20 feet away and squirt that extinguisher at it, either.  You've gotta get right up close and peronal with that fire in order to beat it.

 

If you look at original Speedsters, they had some sort of "emergency" hood and trunk releases, coming out either under the car or in the left front wheel well.  It would be good idea to do the same. And make it out of a piece of steel rod, not more bicycle brake cable.

 

Also, maybe keep a set of welder's gloves taped up under the dash right above that extinguisher to help open the hood and to hold it open while you go to work with that extinguisher.

After seeing, a couple of years ago, that same photo of Ron's toasted speeder (as I recall he didn't own it at the time) I measured and diagramed an emergency engine lid release cable that would be attached to the spring loaded 'catch' mechanism, and exited behind the left rear tire...just reach in blindly, pull the exposed finger ring, and pop it open!

 

My idea went nowhere because in an engine fire I'd need struts to hold the lid open instead of fumbling with the dangling 'pin on a chain' that VS's have...There were  so many confusing opinions at the time on the virtues of various struts that I let the idea go dormant. 

Carl;

 

I have one of those gas powered lifts. I suspect, after consideration, it is subject to the heat of an an engine fire and may:

Not open, and secondly may open and then collapse due to heat.

 

I have yet, an uninstalled suppression system. Not worried, the car is up on blocks. Any how, in an event, as long as no ones hurt or worse, that's what insurance is for.

Congrats on your purchase. Dr is right . Clean out the low idle jets and balance the carbs and it will run like a dream.
As far as fires go - two causes with Aircooled motors 1- old dry out or dirty oily fuel lines. The engine heat takes its toll on these lines. Hard tight bends in the fuel lines is also not adviseable. The lines stress and eventually crack. Hard piping fuel is always good. You just need a flex hose section outside the engine compartment to aid in the engines movement . 2-valve guides . Yes if you loose one you have a 50% of a fire if you are driving highway speeds.
Remote haleon Fire suppression systems are a great investment especially for fiberglass cars . It can save your life , and your car. They are very easy to install .
Have fun with the ride.
