hi mate best thing is to start from scratch, check glow plug is still glowing,are you using a starter box?if so make sure its fully charged and lined up correctly (take out the engine and line up through chassis) and if its still not starting even when warmed i would go onlineput the engine make into google and reset all needles to factory settings at least then your starting from scratch,take of the fuel line from the top of pipe and blow the fuel into carb it should start now,

1st thing-Charge up glow starter, starter box batts-if you have them.. Make sure its all funnly charged. Put the piston at Bottom dead centre/make sure the flywheel moves. Maybe try new glowplug and see if that helps.. make sure fuel is getting into the carb and your idle screw is in a bit more. Heat the engine case up then try again.. in short bursts..Was it running ok when it did start. I.E. Solid idle ect? as it could be too rich, too lean, idle not gap not large enough.. soo many variables..

hi, thanks for the advice, it was running fine, then the next time i started it, when i applied about half throttle it cut out. I left it to warm up and it still did this, i then thought id read up about the engine ect, i tried to start it again today and it wouldnt start, ive check glow plug charge ect. Do you think resetting to factory setting will get it running?
cheers for your help guys

yea I would put the needles back to factory setting and maybe lean it out from there quarter of a turn.. And fully charge glow igniter batts and stuff. So its all ready and try again tomorrow..
It's either a bad tune-When it cut at half throttle did it struggle to gain speed.. as it could be too rich.. or too lean.. but putting it back to factory setting will solve the tune side of things.. another possibility is glow plug it shot-How much use has it had? and when you do it try a few times then stop.. as flooding the engine makes it worse. And before you start it-Factory settings on needles maybe slightly lean them out so its not sobbing rich then-put your finger over the exhaust tip and pull a few tugs on the starter cord-Or starter box until you see the fuel enter the carb then stop.. then heat it up a bit-Hair-dryer heat gun not a soldering iron!-on the Casing not the head.. then glow igniter then try again.. Patience!

Let me know how you get on!
