I rebuilt the carburetor...It would start only with the choke off and it was barely running. If I open the choke, the power would increase but then with a couple of seconds it would die. If I move the choke off to about 95% there, I gain more power...after 5 minutes it died. I then went to clean the spark arrester screen...now it will only stay on for a couple of minutes (full choke) but barely running.
There is no air leak. It has a new fuel filter, hoses, fuel (Before I made this post). I tried to see if unscrewing the fuel cap while it was running to see if that made a difference, but it did not.
What is the next step? Thanks
