The Stovebolt Site Forums The Shop Area Engine Shop running rich

took my 235 out today and after installing a new carb and new fuel pump i am running rich , i can tell by the smell now i have adjusted the choke and fast idle and air mixture and floats ,, what else can i do , it starts ok and runs ok only at idle it does this i can even see a tad bit of smoke ,

thanks

There is a vacuum hole in the bottom of the carb. There must be a passage in the gasket to allow vacuum to get to this hole. You say "new" carb. It probably is a rebuilt or reman. Most of the time they are not right. You need to check the float level & make sure the power valve is working correctly. Its possible it has the wrong size main jet in it.

The float is fine, i dont know about the jets? I did use the base gasket with small ports that came with carb, i have 2 carbs form rock auto, they sent me 2 . I need to send 1 back after i get it running, ,,1 carb had 2 gaskets they said it was due to maybe being warped, but they are checked out on the bench, but i went with the one with 1 gasket, i guess i could get the jet from my origianal carb i changed for other reasons , so it mighthave the right jet

Thanks
