adjusting idle speed/ hand held tach?

[txchainsawgogi]

So I really need to adjust my idle after the rebuild. It runs and starts great but it sputters after it warms all the way up.

It doesn't die(fingers crossed), just sputters a bit and has a little shimmy to it.

Oh yeah, only at a stop or just coming from a stop.

My haynes says I need a hand held tach... autozone, o reillys and napa didn't have them. Autozone even said " we can't even order them anymore".

What do I do?

Don't worry about ur idle until you fix your sputtering.

well i figured their related as it only does it when im stopped, as in when it idles. it feels like it idles too low.
if i keep my foot just lightly on the gas it fixes it.

i've watched the carb while it does it, all the linkages are fine and the butterflies are operating properly. everything in the carb is how it should be...i went over the rebuild twice.

it only started doing it after i rebuilt the carb. im thinking the previous owner fiddled with the idle screws to try and compensate for the fact that it needed a rebuild.

OK. They said no go on the tach? They don't have a small performance section at any o'reilly's? Wow. It doesn't have to be handheld. You can just hold the gauge while you're under the hood.

Perhaps you have a vacuum leak causing the sputtering, and the PO compensated for that by adjusting the carb.


I agree with Vile, fix the sputtering first, then worry about th idle as the sputtering will affect it if you try and set it first.

well im doubtful there is a vacuum leak, as the carb itself has new gaskets and is tightened properly. the hoses are all really snug as well but i can double check those.

i was thinking about an aftermarket tach anyway... are they pretty easy to hookup?

[TexasRed]

Just a power wire, ground wire, and tach wire.

Many other places for a vacuum leak than the carb.  Anywhere on the intake, for example....

Why don't you buy an advance timing light with a tach?

[txchainsawgogi]

I already have a timing light...I didn't think about it. I don't have a timing tab anyway thanks to the previous owner removing it? Haha.

Is there are mark on the block and balancer?

Nope, not that I can see.

Installing a timing tab would make sense if you are concerned about setting your idle speed to spec according to a tach don't cha think?

Another option is if you don't have a good meter, purchase a new meter with an RPM probe.

FINE i'll suck it up and take off the power steering pump and try and put it a tab on there. how do i remove the pump? will i have to flush the pump or anything fluid wise?
