hello all,
backround iam a 30 year old mechanic,(20 years XP on engines) being sent mad by this tiny little engine. i can understand the basics of my slide carb, but ive had trouble getting the initial set up for my engine to run (Cyclon evo 4wd) 3.5 ccm Jamara).this was bought second hand so i have no paper work for it. the problem.

I can get it to run prety fast for about 10-15 mins not always full thottle, and then it will sooner or later cut out (i beleave due to heat) so i allow it to cool and then try to restart, mostly it will start, with some effort and run at tick over UNTILL i remove the glow starter, then it simply cuts out this happens almost all of the time ie it will cut out within a second of the glow starter being removed, ive removed and comparred the glow plugs to new and unused plugs and there seems to be no difference but a new plug will normally get me running again (ive gone through about 10 glow plugs inside a week.

any help or hints and tips would be greatly acepted
