Hi Dave.
I have a small problem with my YS 110 engine. It would not run straight from the box, no idle and would not reach full throttle without dyeing, after speaking to ys service dept I cleaned the regulator out, which was full of debris, including pieces of o ring. anyway the engine runs fine now apart from , if it idles for more then 20-30 seconds it just dies, or dies when I open up ther throttle. It transitions up and down cleanly with no hesitation at all and runs great in the air,. Do I need to adjust the idle needle, or the regulator to stop it cutting out? Fuel is cool power 20/20, os f glow plug, 15x8 prop. brought the engine new last October in Vegas but have only just completed the model to put it into, so if it needs to be repaired/ overhauled where in UK do i need to send it to?
Many thanks
Darryl
