Hey all. I've been spending some time under the hood of the Tree-18 today. Still having some problems with the tractor not running well (close to at all) at full throttle or a load. It boggs down and backfires as I move to WOT. Nothing near a smooth throttle response. It idles great. I have also got some coughing out of the bowl with a little flame. At about half throttle it hunts and surges.
So here's what I've done:
- Carb teardown and cleaning. Took the top off cleaned the jet in front. Emptied the gas reservoir and blew it out with approx 10psi. Blew in the bowl too. Put back together correctly.
-Adjusted the carb. Turned idle mix screw in all the way and backed out 1 and 1/8 turn. No effect on the full throttle problem.
-Checked for intake leaks by slowly covering more and more of the carb opening. As it got close to being fully covered it started to choke out and die so I don't think I'm leaking air.
I'm thinking this may be electrical. A similar post on WFM indicated the same problem being rectified by a points and condenser. You think that's me too?
Also , the voltage regulator is still dead and out of the circuit. Battery was charged up full last night. Picking up the new VR on Monday.
Thanks all.
