replaced primer bulb
Expert:  JON replied 3 months ago.

these are one of the simplest engines there is and this has me stumped so far. remove the cover and make sure the intake tube is not cracked or broken.

Customer: replied 3 months ago.
had intake tube off cleaned checked gasket, primer shoots gas in carb 2 or 3 pulls starts runs 30 sec. or less then quits
Expert:  JON replied 3 months ago.

I am unsure then. its not pulling its own fuel for sure. If the pick up tube is good, the gasket, diaphragm, and spring are good, carb is clean, and primer is good, it should run. there is nothing else that helps put fuel into the cylinder

I know that's why I'm stumped

oring on the back side of the carb?

Sorry, just trying to thing of anything

ive had this issue with a cracked carb before, but you stated you have used 2 carbs and 1 from a running machine, so it has to be another issue other than carb

o-ring and retainer are there
Expert:  JON replied 3 months ago.
