Registration Frustration Blues...

First thing to do when diagnosing engine probs is to do a compression test on all cylinders.  If you have a low compression cylinder or 2 it will never run right!  Low compression can be mis-adjusted valves, bad rocker arm, burned valve, Stretched valve stem, wiped cam lobe, bad valve seat, crackled/holed piston, bad cyl/head seal (would make engine loud too).

First I do is pull one plug wire at a time to see where the issue is

 

 

That was my first thought and I did a compression check on all four. And I was getting a hundred and twenty pounds all the way around. I just now changed out the fuel filters and noticed that I neglected to reconnect the carburetor on the left side. Possibly the cause for it to be running erratically... I'm now going to go through the process for the initial setup again.

When The engine was running was running, I pull the plug wires from the distributor and some I noticed a dead drop others I just noticed a decrease in RPM. Previously, I put a unisync I need Barrel while I was running and I got erratic readings on all 4 barrels. That is, the ball continued to jump and wouldn't stay at any given level.

I've got to step back and take a breath; especially since the car runs like crap.  I have pulled off the carbs and cleaned them and readjusted them, put on a set of 40's and they seemed to run better...for a while.   Then they took on similar characteristicss.  I don't have that much money so I'm ordering a new set of empi carbs.

Don't waste your money on a set of empi copies.  Rebuild your webers! 

Sound like dirty fuel... Check fuel tank, remove screen at bottom of tank, put new a new fuel filter in line. Clean the idle circuit. Blown carb clean in the idle jet port, remove mixture screws and spray carb clean there also. 

Set the mixture screws at 1-1/2 turns out, adjust linkage. And start it up. 

Oh, what fun: the trials and tribulations of the infamous Weber carb. LOTS of go-'round here about that.  Idle jets, idle jets; idle jets.  And when everyone else tells you to look hard at the ignition, check the idle jets.  And mind the little brass thingies equipped with self jettisoning springs.  Neglect to watch carefully, and this can cost you many weeks and at least 20 pages of thread.  Just sayin' . . .

I noticed my set up in the back that there's a tea setting with fuel lines going to the left and to the right. the line going to the left show's a full fuel filter. The one on the right has barely anything except on the bottom. I'm going to split the line equally. Maybe the right carb is starving.

Now you're getting it Meade. Perseverance my friend.

.… The only time this car is happy is over 3000 rpm...

I think this tells us the problem isn't with restricted fuel flow to the carbs. If so, the stumble would get worse the more the throttles are opened.

It's more likely dirt in the idle jets OR the idle circuits - which are two different things. Besides cleaning the jets themselves, have you blown carb cleaner into the ports on the carbs that the idle jets screw into (after removing the jets first, of course) ?

Remember that, unless you're climbing a hill, up until about 3000 rpm, you're driving mostly on the idle circuits.

It could also be synch problems in the linkage, which tend to be less noticeable at wider throttle openings, but very obvious just coming off idle. If you can get it to idle smoothly and it stays smooth just as you start to give it very light throttle, the synch is probably in the ballpark.

 

I think it's time to shine the big floodlight up in the sky with the DP on it.  Danny Piperato could solve your problems with the tools in his utility belt.

I overtightened my right emergency brake and that was impeding my forward motion somewhat...and after loosening it up I was able to go forward (and backward) much more efficiently.  I think I may have a bad seal on my right rear wheel, but I won't know until pull the wheel tonight.  I could see grease on the lining when looking through the inspection hold.

I think I got the carb relatively clean when I had it out; I unscrewed everything I could unscrew, removed all the 'soft' parts I could and dunked everything in carb cleaner and then blew everything out and reassembled with the original parts.  I examined all the internals everything looked good to the eyeball. (this is the same process that the shop went through).  I have not pulled the gas tank, I am running carb cleaner through my fresh tank of gas, and I checked the lining of the gas lines when I had them off, so I that part is taken care of.  I did an 'initial setup' of the carbs again last night and it still doesn't want to run on the primary on one side....sigh...

Good morning physics class. What we've done so far was, I pulled the gas tank got rid of the loose stuff inside it, treated it, reconnected everything, turned on the pump, and...still only got about a 5th of the volume pumped on one side as opposed to the other. (I pulled the lines leading to the carbs and stuck them in different containers aND turned on the ignition for 2 secs.) I disconnected all the lines and cleared them and checked the T fitting. I ran the test without the filters. What am I forgetting??

If I understand you right, the end of end line after the T your feel you have more fuel flow than the other.. If so. Don't worry about it. Once they are connected to the carbs, the needle/seat for the float controls the fuel flow.  I have seen those "t's" collapse when tightened.  If your doing all this I suggest get a brass t block, tap it for a fuel pressure gauge.  One other thing if you pinch the hose closed that flows good does the other hose begin to flow more?  

As Anthony said, once the lines are connected and there's pressure to both carbs, fuel will flow equally.

Meade, I think it would be best for the forum member to keep you other "Carburetor" Topic alive and leave this one for the "Registration" issues.

Ok, makes sense.

efreshed your "Brass T" topic with my 2 cents.

But you should listen to someone like Anthony who has WAY more knowledge then I on the topic. I will paste is comments above to the "Brass Thingie" Thread for others to follow...

Any luck with registration?

I have to keep prodding the guys down at the  state office. I spoke with the guy on Tuesday and he said he was handing the whole process over to another lady. I called on Friday he said that he thought that she had already processed it but when he checked with her on it she hadn't touched it.This guy thinks it will go through and I should have my paperwork pretty soon. Keep in mind that they lost everything that I had sent them.

I’m on my computer now and can respond better. Do you think I only need one filter? By having two, I was able to tell that one side wasn’t getting/much gas. Does having two filters diminish flow?

I don’t have any one around help me so I can’t pinch and watch the flow of the lines.
thanks
