I have bought a car off a friend and i've seen the engine running a while ago, since then the carb became loose. When i got the engine i fixed the carb and check for any air leaks - none fuel was pulled throuh when turning it over fuel mixture was correct. I have built my own glow driver which puts out about 1.5V the glow plug glows brightist red with that - but the engine would not start, not even a hint or any ignition - i upped the voltage to 2V - glow plug now glowing white - engine started but after it had turned over about 2 turns it stopped - check the glow plug and it had burnt out - i had checked the glow plug on the bench for about 30secs to make sure voltage wasnt to high - is it my glow driver at fault here ? ( i have another engine showing similar symptons allthough i managed to start it on 1.5v after about 2 hours and a hair dryer !!! but havent managed it again ) what am I doing wrong?!?!?

Thanks
