Marvel carb HELP

[60redfacer]

Hey guy can anyone give me some insite on whats wrong with my carb. It's the cast iron Marvel, I recently rebuilt it and made the engine run good. But now its back to its old ways, leaking gas back out of the air inlet opening. I tore it down soaked it for a few hours in chem dip and used a new rebuild kit. I'm thinking that the needle is staying open and overfilling the bowl. Any ideas before I go and buy a new carb. Thanks

Don't replace it take it off pull the bowl remove the float submerge it if it doesn't float evenly you have a bad float I just replaced the float in my 80 because of one side of the float was bad. Also after you check it readjust it 1/4 inch from top of float to bottom of gasket this is crucial you bend it near the needle to set the proper height I am not pos about the quarter in I will double check for you when I get home. Finally while you have it apart make sure you don't have anything that was in the gas obstructing the needle, good luck the marvel is fickle
But simple

I had to have the float balanced in one of my 200's. I just told them to rebuild the entire carb while it was there. $65 bucks was worth it, not to bad of price in my eyes. It has not leaked a drop of gas since. Mine is also used 4-6 days a week.
