I run one on my pickup and had the same problem at first. Was the needle seat not sealing correctly and loading up the engine. Then, once I got that issues resolved, I had to clean out my metering block due to one of the idle passages were not functioning correctly. Did you check your float level at idle? Is there fuel leaking it the engine from the boosters? If so, change the needle and reset your float. Hope that helps.

sounds like your acc. pump isnt working right.look to see if fuel is coming out of squirters when you pump the gas.

Extem4u, just had another thought on your accel pump. I had a similar problem with my 4-brl where both squirters would not work after sitting for a while. Come to find out, the pins/needles under the accel squirters were clogged and bound up. I had to remove the squirters, get the pins out, clean the ports, pollished the pins, and then my accel pumps worked fine. If you push on the accel pump lever with your finger, do you feel back pressure? If so, you might have a typical problem. Last resort is your bowl gasket is overlaping your fuel port and blocking fuel between the bowl and the metering block.

I would take carb apart and clean it real good if its been sitting awhile.check for vacuum leaks and correct timing too.

If that fails you should send a PM to KPLugnut he should be able to point you towards the problem
