  • 67303 is rated 2.0 out of 5 by 1.
    Rated 2 out of 5 by from Liar liar! They say every carburetor is test run on an engine. I thought I could hook up my fuel lines and turn on pump and level would be close. I have a dragster and by the time I got back to engine to check site windows gas was overflowing into the manifold. Float adjustment was almost all the was down(as low as it could go. I turned it in the last little bit and when I went to tighten set screw the cheap pot metal screw twisted off before it was even tight enough to hold the 6 lbs pressure. The other float adj is maxed out too and bowl is almost too full.Just firing up on a bowl full it still wouldn't idle and when checked the screws were 1/2-3/4 turn only. No way this carb was running!!!!!!!
