Well, that was a big waste of time. (IMG:style_emoticons/default/mad.gif)

Re-cleaned the idle jet for that cylinder and I even tried Dan's suggestion and it didn't help.

How can I tell if it's the idle circuit and not just the jet?


If you pull out an idle jet, your idle should change. That is one way to know it's clear. Most of the time it isn't the jet itself, but the little passages to and from it. Test a barrel, pull one out and your idle should change. Stumble or pick up, either doesnt matter, but change. Drastic, you could take a little carb cleaner with one of those little red straws and hose it down with a little pressure.

My carbs are so crappy right now (Car not driven enough either), I swear every other time I light it off one of the friggen idles is gummed up. Driving it around usually clears them up. Sometimes I'll get anoyed, pull over and do the finger thingy. It works, car smooths right out. I am running Zeniths though, that might be different than webbers?

I hooked up my timing light to verify that I'm geeting spark to that cylinder and it looked good.

When I pulled the idle jet out while it was running, nothing changed. Is that any type of indicator?

Yes, air is not passing through at all. If you pull your jet out, you have basically removed the metering of idle air and that cyl should either pick up the idle a little or make it stumble. Usually when I remove mine, the idle picks up as more air passes through than should. I know a circut is clogged when I remove a jet and nothing changes.

So how do you un-clog an idle circuit?

I don't know where on your carbs it is but on idf's there are air ports on the top of the carb with a sized brass
jet that feeds the idle circuit that usually get clogged also.

Is this something that is accessable if I remove the air filter assembly?

Should be....you'll have to take those gloves off though..... (IMG:style_emoticons/default/shades.gif)

BTW, they make some pretty neat insulated plug pliers that work well....

Okay, here's the problem carb. The arrow indicated the idle jet for the #2 cylinder.

I didn't see any place to access the circuit. Any ideas?

take the jet out and spray in the hole.
Also the big flat head screw head below is a plug, The transition ports. Spray in there too.

Did you pull the spark plug out and check it ?

Yep, pulled the plug and even replaced it.

Should I go ahead and do this to all three?

I pulled the idle jet and the plug you mentioned.

I noticed that after a squirt or 2 into the idle jet port, carb cleaner shot out of the hole on top.

Just so you feel not alone....from the 356 old phart list....

> I'm in my 22nd year of 356/912 ownership, and its seems to me that the
incidence of clogged idle jets is on the rise, at least based on my own small
sampling.
>
> Here in NH, ethanol fuel blends have been the norm since May 2006. Most of the
US now uses an ethanol fuel blend. Ethanol gives gasoline a different solvent
property, and has been known to mobilize years of accumulated crud in fuel
systems. It seems to me that since the switch, my car has had more frequent
"idle issues", usually related to clogged idle jets. This has occurred even with
regular changes of the fuel filter.
>
> Have others noticed a similar trend, especially the pro's who service many
cars?
>
> As an related aside, some years ago I took the advice of Alan Klingen at The
Stable, and started using an infrared thermometer gun to diagnose idle problems.
A clogged idle jet is easily detected by the relatively cold temperatures of the
exhaust pipe exiting that cylinder. It's way easier than messing with mixture
screws!

Success!!!

I guess I must of had something blocking the idle circuit. It took awhile, but after 5 or 6 attempts at dislodging whatever it was with a can of carb cleaner, the #2 cylinder is firing again.

Took it out yesterday to Buttonwillow and she seemed to run very nice.

Still got a small issue with an intermittent back fire out of the exhaust but nothing I'm going to worry about right now.

Just time to (IMG:style_emoticons/default/driving.gif)

Thanks for all the assistance... (IMG:style_emoticons/default/beerchug.gif)

good! if the problem becomes persistant i would suspect crap in the float chambers.

are the spring loaded screws on the bottom of the carbs the idle/air mixture screws? like on IDF series webers? if so, if turning one in and out fails to have any effect, suspect that venturi's idle jet/circuit. carry a little can of compressed air. the orange tube slips way into the idle jet housing hole. manually blowing out an idle jet gets old. blow air backwards thru the jet so you don't jam the bit-o-crap in further.

Allan,
Have you considered doing a four cylinder conversion on that thing? (IMG:style_emoticons/default/biggrin.gif)
