Just put my q-jet back on the car today after taking off the Demon, and now have a loud sucking noise. Sounds like it's coming from the top. I put a new gasket on bottom and retighted everything and went so far as spraying ether around to see if i had vacuum leak and didn't have one. don't know where to look next? appreciate any advice, thanks Sean
Does the carb base gasket have cut outs ahead of the rear mounting holes? Some q-jets need the straight one's. Straight along the sides from the sec bore back to the mounting holes. Just flip your carb over and match the gasket to the bottom of the carb. And look for any cut outs in the webbing on the bottom of the carb. Fairly easy to see where the air can get in if it the wrong gasket. Hope this helps
Yes it does have cutouts, I'll take it back off to check it more thoroughly. thanks for the reply. Sean
