The only things I can think of are...plugged air filter, plugged fuel filter/line, mixture settings or messed up carb, clutch bearings(are rear wheels on the ground?).
Oh yeah, and toasted piston[:@].
When it starts up, how does it sound? Bubbly and soggy, or crisp and lean?
Do you have temp gun?
First reaction...plugged fuel filter, or a piece of flashing from mfg. on the fuel inlet in the tank acting like a one-way valve.
just a shot in the dark
This is what I have checked. all needle setting set back to normal, owb, new carb (cause I took it apart to check the hsn and the threads pulled out with the brass part) New fuel, Cleaned all fuel lines (blew out with air) Pressure checked tank in sink of water to check for leak's, Took glow pug from revo put it jato and glow pug from jato work's in revo. So I think that motor is done.
When it starts it sounds normal. runs for 30 sec or so then dies. If i take it off the bench put to run it, it runs at 1/2 to full but as soon as i let it come to idle it dies. ??????????? Not sure what it is I wish I had a compression gauge! I would think if it was an air leak it would either have a high idle or not run at all. I have a temp gun but I don't remember what they were.
Thank's for the help!!
