tuning a 4k carb


v3k

Recommended Posts

Hey - I have my corolla engine back together, it starts (with choke) but wont idle without even after a good warmup.

Does anyone have a Haynes manual they could scan the page in with what screw does what? Or if there is an easy way to tell me go ahead :D

Cheers for any help :D

ok sweet - got the thing idling (a little high I think, but no tacho = no accurate idle)

Now tuning... the air fuel mixture. What is a good approach? It not longer blows brown/black smoke after throttle... but how do I know its not running too lean? Or is this a jobbie for someone who is more than a backyard hack?
