ill expand on my dilema. 2 strokes aren't my thing but I was doing this to help a person out.
he bought this 3 months ago,ran fine until about 2 weeks ago. had to start pressing the gas all the way to start it,it would idle but when u gave gas,it would bust up and not really go.This is what he told me how he got it to start and run.
he premixes 50-1 but the oil injection still works.
I get it home and I never could get it to start.he said it would take awhile before it would fire with him.
anyway,i can shoot some carburetor cleaner in the carb and it will fire n run.if you keep shooting it with cleaner,it doesn't run.only that initial start up will it fire.
when it does fire n run for about 4-5 seconds, it smokes like mad. I assumed this was the 2 stroke smoke itself. Engine sounds healthy and he said it ran fine until it started the hard starting/idle issues.
I brought it to fix for him because he said it would crank and idle but not take gas.I figured easy enuff carb/vac problem and have him on his way.
carb is cleaned 100%.new plug.new gas,new oil,getting fire to plug etc etc.
