First off Merry Christmas, Happy New year and Happy Holliday's to all.

ok now to the question, My jato has just over a gallon of fuel through it. I was running very well, I put it away for about a week or two. (after run oil used all the time) I took it out and filled it up (Dynamite Blue Thunder 20%). It started up quick ran for about 3-4 minutes then died. Now When I try to strat it it will run for about 30 seconds and die. I have Check the following. Tune (reset back to factory) Fuel tank. pressure test in water, all looks good there. Glow plug changed (McCoy 59) So that is what I got. Compression seem good. I am just at a loss. I have tried everything. Any input will be great. I don't want to go buy a new motor right now.

when it dies how does it die? does the engine cut and the spur gear spins or what? more info plz

I will get it out in a bit and check to see if the spur spin's when it shut's off.

I myself am having problems with my jato (and my lst2 another story) and when I first take it out I cant get it to start. So I tried priming it with my finger over the pipe and I see the fuel go threw the line but it still wouldnt fire. So I took the fuel line off and I wasnt getting any fuel threw the line it looked like I was, it was getting there but it just wasnt flowing into the carb. After getting it to flow with the line off the carb I stuck it on and it fired up with no problems but if I empty the tank or run it dry I have the same problem all over. I would try taking the fuel line off and see whats going on, but I still havent figured out what the exact problem is myself. Any ideas anyone?

Also, merry Xmas all!

Maybe the fuel? Did you keep that bottle somewhere where it could go bad? I would ditch that BT fuel and try something more consistent, like Trinity Platium. Personally, I use O'Donnell and it's awesome.

I tought it might be that but it works good in my new Revo. So now I am stumped.

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!!

when u come down to an idle from high rpm does it sound like its rich when its cutting otu, coz some of my engines have done that b4.

Dann

Just dies!! let off the gas ond stops running.

Try this:

HSN 4 1/2 - 4 3/4 turns out
LSN 2 turns out

adjust idle from there

why so rich? I will try in a little while.
