hi,
the engine is new and only had a 3 tanks through it. The last time i used it was when my plane went in on its first flight. the engine is now on a new plane and won't go. im 100% sure its plumed up ok and got no leaks as it holds presure. so at first i thought it was a blockage but i striped the carb/air box off and it was spotless and had no blockigise i also blue throw the inlet valve to make sure that was not bloked which it wasn't.

i reasembled the engine with new gaskits and still no go but i found out it runs for about 5 seconds if you put fule straight into the head so its just burning of that bit. fule is geting into the carb and the pump is also wooking[&:]

so any idears what else it could be? im stumped

Thanks for any help...... Andrew
