Were you sure to install the piston with the cutout portion of the skirt facing the carb side of the engine? If not installed correctly they will flood very easily and not run correctly if/when started.

I did that with my 3.3 the first time i rebuilt it ,had hard time starting it but it ran good .

( untill the skirt broke piston stoped on the up stroke and split the con rod strieght down the middle and went through the top of the piston)after that i just did the trade in . point is if you rebuild make sure you pay attention to the way everything came out cause ,it cost a lot of $$ to do it twice.
