I'm running a TRX 3.3 on 25% Tornado fuel.
I have a new tank fitted and have fitted new fuel lines. The air filter is cleaned regularly.
I have returned the engine to factory settings and tuned from there, getting leaner on both HS & LS needles.
The truch seems to start quite well, euns really nice when its cold but after a few minutes just stops and then takes a while to re-start.
I've tried the pinch test when the ngine is warm, but it just stops, no rev-up.
Temps have never exceeded 220F and the ambient is about 65f at best.
I seem to be going through plugs quite quickly, the last one, an OS No8 lasted just one tank.
The attached images are of a McCoy MC59 (on the left) and an OS No8 on the right.
Can anyone offer me any tuning advice at all please?
