I cannot prime it with my finger over the exaust. I have to blow from the stinger.

Brand new fuel line and no leaks in the fuel tank.

I have noticed that fuel does sometimes leak out the LSN on the rotary carb. But Im going to recheck that too see if Im correct.

Check to see if the glow plug,heat sink,and the exhaust header are all tight.I had that happen to me.

Clean or take off your fuel filter if you have one also.

GOt none of that. Its never been able to prime by the stinger.

SInce i first tried to start it.

Its a month old and has only had the breaking + 3 more tanks through it
