I'm the second guy to look at this motor (J6RCUD) - it will not keep running. I pulled the carb apart cleaned it (was not too bad) put back together. Seemed to run fine for a while yesterday then I tried it again today - same problem running supper rich, dieing out, smoking. I tried to adjust the carb no better. Makes no sense cuz yesterday it seemed fine. I have a hunch its the stupid primer choke assy. First I would like to know if its hooked up right. It has two lines on it. Does the big one go to the bottom of the carb to the float bowl - Anyone got any other ideas?
