Idle jets

Hi In my idle moments I cleaned my idle jets. What a difference in drivability! I couldn't believe it. If it's poppin' stumblin, and fartin', clean 'em , 10 min job , SEG for hours. Tom

Tom, while you're at it. Clean the air filters and the air filter bases. Most of the dirt that gets into the idle jets comes from a collection of gunk on the bottom of the air filter base where the filter sits.

Larry,, and Tom,,
I have been having some intermitant rough idle issues. Could it be the idle jets. How does dirt external on the carb and filter base affect jets,, and what is the cleaning procedure ??
thanks,
Alan

The idle jets could be the problem as could timing, points, condenser, mis-adjusted carb's, dirty fuel/filter etc.

In my post above, I'm refering to the floor of the air cleaner base confined within the air cleaner. You can remove the base and wash or use brake clean and carefully clean the base.

thanks,, Larry,
I understand what you mean now, about dirt inside the base. What is the procedure for cleaning the jets ?? Tom says that it only takes 10 minutes.
Alan

I use a twist tie with the paper peeled back.... Insert the wire into the small end of the jet and unplug and gunk. Spray with brake clean

Do you leave the jet in place?

Someone, maybe Larry, suggested coating the airfilter base with grease to help prevent gunk getting into the carbs.

When I first got my car, I keep having problem with the idle jet getting clog. If you have the Weber IDF you might want to put the CB Performance IDF Jet doctor : http://www.cbperformance.com/catalog.asp?ProductID=1507 this help prevents the dirt from coming to the opening of the idle jet. Another advantage that I find out after putting this IDF jet doctor is that if the clogging is not too bad, I can just put compressed air to the tube and usually it clear the clogging without having to take out the idle jet which can be a PITA

Using compressed air through the passages with the jets installed is BAD !!!! Don't do it. Under certain conditions, it can pack junk into the passages and into the jets. Sometimes you'll get away with it, then when least expected, you'll pack the carburetor passsage ways with crud and will have to disassemble the carb's to clear the passage ways

Remove the jets, then clean.

K&N makes a real neat grease, not like axle bearing grease but more like thick hair gel. It's used by off roaders around the base and lid of their air cleaners to help trap dirt. A VERY thin coating of this grease on the floor of the air cleaner base will help to keep crud from entering the idle jets.

Vasaline?

Is that a request?, a proposal or what?

Idle jets in IDFs are the very definition of PITA. The idea for sealing the base w/ vasilene(?) is really good. Will try that ASAP. Rain caps and/or the jet doctor may be the way to extend time between cleanings. But the problem is inherent w/ the design, as I see it, so you'll be at it again and again.

Amazon sells the K&N grease.

Amazon...Grease...to easy. Vince what do you have to say?

I say Kadrons - two years now after install - have not touched
KISS

Dale, my TD-driving brutha! Same here with the Kadrons on my VS!

kads are single barrel's. IDF's are dual barrel. one carb for each cylinder. a completely different beast to tune.

There is a lot of really useful info on how to tune them on thesamba.

All this lubrication talk there's surely a marriage in the making ~ or at least a faux... " I Love You "

Yeah, I don't think you'll see anywhere near 180hp on Kadrons.

I'm just saying(thanks Jim)!

I can see where it is a real PIA for you Speedster drivers, not so for us Spyder guys. After Carlisle, the same jet clogged once so far this year. Five minutes later I had unclogged it and was underway again. It would be great if you could get different manifolds that fit Speedsters but reversed the carbs, leaving all the adjustments and jets accessable from the inside. Possible?

Keep your air filters clean, seal them up with grease or vaseline, and most of all once carbs are synched, leave the air filters alone. Just the act of removing the tops can drop enough dirt to clog a jet.

Also, use good filtration, and make sure your accelerator pump diaphragms are not disintegrating from todays fuel.

And KEEP THE WATER OUT!

Is this the grease?

Marty, yes.

Danny, my Weber DCNF carbs from Berg are reversed.

Danny,
I know yours are duals, but most guys are not running 180HP in their cars and I think many engines have carbs that are oversized. It seems almost a running joke around here w/ all the carb problems.
I may be undersized on my new engine ( 2110 ), but will upsize if required.
Dale

Dale, they sell Extenze for that:)

just to clarify - you guys use some sort of sealant on the idle jets?

i'm about to put some new ones in and am wondering if i should be doing this?

Mango,

I believe the idea is to put grease under the filter elements, right on the air filter base to keep dirt from accumulating and then drifting down the hole and into the carbs, which are vented, or into the air inlet for the idle jets, which are right there on the top of the carb. The grease will keep small particles (and only one small particle will do the deed) out and will catch and trap them when you R&R the filter. Very clever idea here that could save a bunch of trouble.

Will flypaper work ??!!

Sorry,couldnt resist.
just have a natral aversion to oversensitive geschefts.
