my truck runes fine until I run it for a while, when I press the gas it doesnt stall it just acts like it dosent have the power. Also when I run it for awhile it just dies and wont start again.

You might be running to lean on the LSN? Do you have a temp guage? If you let it cool for about 10 min will it start again?

The reason I ask is I have a simaler problem and what I had to do is richen my LSN about a 1/4 turn then readjust my HSN after a few runs. The new slide carb is a pain in the butt to tune but Got to Love those whellies!!!!!!!!!

I gave up on the Blue wire and started using a Glow Plug heater because the new Easy start does not provide enough juice to the plug. The old one did not either but it was acceptible and would restart quicker.

I am still educating myself on the new slide carb. My older Pro .15 would run no matter what unless I got close to the 270 redline. Everyday is a new tuning day for nitro engines and you have to tune for that day.

Hope this helps

I was having the same problem. Evidently the factory settings are to lean. I was so frustrated that I was about ready to sell the thing. Yesterday, I got it out and richened it, then I started leaning it at 1/16 at a time until it started running a whole lot better. I finally ran 2 tanks of fuel through it without it shutting off. It was 80 degrees and the high needle was set at 4-1-4 out and the low I believe was at 3/4 or 1-1/4 out. I would suggest putting your low at 1-1/2 and high at 4-1/2 and start leaning it very slowly until your running without it shutting off. Remember the manual says 1/8 at a time, I ended up moving it about a 1/16th. It's very aggravating but once you get it set you will be satisfied. Good Luck, Tony
