the idle is iffy on this one, not sure if its carb or conversion related. the ls needle setting is super sensitive ( like me!! lol). after i set it to run best, the tiniest adjustment( 1/32 of a turn to rich or lean) has a major effect? carb is clean , needles are in great shape, compression was at 89 and 90 dry. thoughts? i may re-kit another carb and give it a try .
