Ok, so the fuel was fine. I go out to run it and tune it up, and it fires just fine. It starts warming up and I leaned out the hs a little bit, let it warm up a little more and all of a sudden it goes wide open on me. It wasn't the throttle so I guess it was an airleak. After trying to kill it with the safety stop, I tried stopping it with the brakes and closing the carb off (I leave the idle stop way out after it ran away before). Didn't even slow it down, then it died. After looking at it for a while I saw a crap load of bubbles in the fuel lines, when I went to blow it all out I noticed my fuel line had a big ass cut in it. So I replaced it fired it back up and it ran ok. Went back to tuning it and when I was good to go set it down and gave it gas..... and nothing, then it died. Tried it a second time with the same outcome. Fired it up a third time wanting to see if the flywheel was loose and notice the remains of what appeared to be my clutch shoes, reduced to dust. So now I have to check the clutch shoes, locate a possible air leak somewhere else, and replace the safety stop after being ground to nothing.

The RC Gods hate me....

Also I hate that damn uniflow mod, it seemed like half the fuel returned back to the tank from the exhuast.
 
that sucks, I am guessing you have a Savy (uniflow), I would suggest a 125cc Buggy tank mod a hell of a lot better imo. And are useing a oneway valve.
 
Ahh I used the bic tube and fuel line, I can live with the mid tank lean after seeing fuel or oil going back up the pressure line into the tank.
 
You are supposed to use a bic tube and fuel line. The thing is the old uniflow mod used that and a oneway valve in the fuel line. =That caused the fuel to go everywhere, Dont use a oneway, it makes more problems then it solves. Use like 12-14" of fuel line along with the bic and fuel tubing. If you do that you will not get any fuel in the pressure line and it will help with the mid tank issue.
 
I did use the bic tube and fuel line, and it was still going everywhere with me. I might do the tank sometime later, but I need to get my truck moving again first.
 
Dude sorry to here that thats more than I can help with on a Friday Evening
