I've recently replaced a seized Atomic 4 with one that is in good running condition. When I run the engine I've noticed a very small resedue of fuel developing on the air intake side of the carburetor. The scavenge tube on this particular carburetor has been removed and the opening has been plugged shut. I originally thought that the fuel leak might have been caused by the needle valve or the float sticking, so I took it apart and everything seems to be fine. So i replaced this carburetor with another. I was unable, due to space constraints and the inflexibility of the copper scavenge tube, to attach the scavenge tube at the flange. When I ran the engine, ALOT of fuel developed in the air intake, and actually started to drip under the engine. I am not sure why this is. Again I took apart the carburetor and the needle valve seems to be closing the orifice properly. Again, could this happen because of the scavenge tube not being attached? Unfortunately on this carburetor the idle screw is seized. But since it had been the original carburetor, I assume that it was set in the proper position. Any help with this problem would be great.
Cheers,
Hank
