Poulan Pro only runs at full choke
Hello everyone. I have a Poulan Pro PPB335 trimmer which has been giving me trouble the past few weeks.
It started off bogging down somewhat under throttle, so I decided to take it to a shop to have it looked at. Well, a couple weeks later, after finding out no one locally will work on it, I decided to do it myself. I mean, I work on cars and stuff, how hard could it be?
Apparently a lot harder than it looks! I tried different gas, no luck. Then I rebuilt the carb, no luck there either! When I changed the gas, it started doing something different. It only runs at full choke! It runs at a midrange rpm, not idle but not wide open either. It will run at full choke for a least 3-4 minutes before dying. If I move it to half choke or open, it dies almost immediately.
It has a Walbro WTA31 carb, cyl compression is 115.
