Ok...I ran with the 142.5 this weekend...and needle on the middle I think it was. It ran pretty well in the garage, and started out dencent on the trail (a friend was riding it). At the first fairly big hill, it just flat out wouldn't climb! No popping or anything, just no power. This was at about 8500 feet. So, almost went back to the truck, but decided to go for it and ride a while longer.
After almost an hour of riding (slowly)...here comes my friend almost passing me. We stop, and its running like a champ! Not tons of power, but decent for a Warrior. The whole rest of the ride, it ran great. I'm guessing it was an electrical issue.
Now I don't know if I should just sell it off to the guy that wanted it...or ride it a few more times, just in case it starts acting up again (don't want to screw anyone over on the sale).
Anyway, its running pretty well....a touch rich right now, but I might just leave it alone unless it starts fouling plugs.
