cant figure out this problem?

[Chimpin07]

well i just got done fixing my vac leak and now its idling really weird. like its idling at 1200 while sitting there and when i give it a quick snap it idles up to like 3k and then comes down very slowing and stops at 2k. and i have to adjust the idle screw to have it come back down but when i do that it feels like it wants to die. im thinking i might need my carbs synced? i have a video of it as soon as i figure out how to post it on here.

Either you still have a leak or your idle circuit is too lean.

What are your a/f mix screws set at?

Mods?

i just fixed the vac leak and tested it and its fine. and i have no i have no idea what the a/f mix screws are at and i didnt touch the carbs on it. and i have no mods just a stock 97 750 kat

how do you post a video on here and ill show you want im talking about

Stock setting on the A/F screws is 1.75 and that's too lean. Try backing the screws out to 2.5.

Still have a vac leak somewhere.

Spray some starter fluid around and see if it picks up idle.. Sounds vacuum leak-like

alright thanks guys ill check it tomorrow.

you have to adjust the idle when HOT after say a ten minute ride.

you cant adjust an idle on a cold engine. if you do it will be way too high of an idle speed.

Well still couldn't find where it was got Soo fed up an frustrated I took to the shop and they said #2 cylinder isn't firing. So hopefully it's fixed soon!
