Re: carby trouble

You might have picked up abit of sh*t and the needle could be stuck. I'd check that first if the car was running ok before. I've had it happen to me but in my case it turned out to be a fine piece of wire. Worked out it came from the braided line after I had cut it. It took 2+ weeks to work its way to the needle and seat.

Re: carby trouble

the nut screws clockwise to lower the float level. The reverse to rise it. I had a similar issue with my carb. Couldn't stop it overfilling the bowls and flooding the engine. The tab on the float needed to be bent a little as the float wouldn't drop low enough.

Re: carby trouble

Do You Have Any After Market Fuel Pump.
The Holley Doesnt Need A Whole Lot Of Fuel Pressure And This Can Cause The Flooding, And Also Make It Run Sh#tty If So Lower The Fuel Pressure And See How Ya Go.

If you haven't already done it, find which bowl it is first and then look at problem. Remove air cleaner and look very carefully over top of carb while trying to start car and see which bowl is problem. If it's both bowls could be fuel pressure problem; if it's one bowl, more than likely crud problem.

Could be needle and seat with microscopic bit of crud, float too high, needle and seat thread stripped has been problem at times.

Cheers
