Hi,

I posted before about starting problems, what happened before was when i tried to start the plane after filling the tank the spinner just span off, with adivce from some guys on here ive learnt now to remove the line to the exhaust then fill the tank using the filler line until fuel came out of the line for the exhaust then i reconnected the exhasut so i know its filled, and havent flooded the engine. I then connect the glow plug and glow plug starter, but now all that happens when i use the electric spinner it just wont turn, seems to lock.............. but when the glow plug is off the engine or loose it will turn..........

So please help someone this is driving me nuts as when the planes running it runs fine........ btw this is still a new engine its had about 7 tanks through it so i gather it should be run in now.

Could this be caused to under primming ? as my instructer told me its not nessasary to prime the engine ? but the maual for the engine states to open the throttle fully and place your finger over the carb and turn the propellers by hand for about 5 spins ? So im abit confused.
