You might want to check your glow plug.

hey when the glow plug is hoooked up to a glow plug ignitor it glows red hot, how do i check if its the glow plug?, the motor turns over fine and gas seems to be comming through fine but it just wont fire and start. ay help greatly appreciated.

[suck my wake]

did you try pouring a little nitro down the carb to see if it will try to fire. if your plug is glowing red hot then its fine
so its a gas problem

hey yea i tried that but didnt do anything, but i got it going but it only runs for like 15 seconds then stops so not sure may need a bit of fine tunning now.

[suck my wake]

before it stops does it rev really high? if it does then its running out of gas

hey na it doesn't rev real high it kinda just goes then stops, so im guessing that it is just some fine tunning needed to get it running properly.

If it just goes for fifteen seconds and then stops, it's just running out the prime charge. You're not getting fuel for some reason. On the upside, that short burst proves your engine has compression and glow, so you have two out of three and the engine itself should be healthy.

Check any in-line filters (they may be plugged) check your lines for possible pinholes, and check to see that your start procedure is right (choking enough?). How about tank position? If it's too low the engine won't be able to pull fuel, you want the C/L of the tank to be about 1/4" below the needle valve or less. Are you using muffler/pipe pressure? That helps if you do.
