hi my name is richard i have a speedfight 100 and its doing my head in -.- first the cdi died so i bought a bypass took me ages to get it running again and then 2 weeks after that the exhaust snapped iv just bought one the same its a techigas and its now running like a bitch also it did leak alot of fuel from the carb i couldnt work out why i cleaned it all up and now it wont go over 5mph and when i stop revving it dies any help would be much appreciated
Hi agree with leroy- but I'd go further. If it's being a pain - have that carb totally in bits, clean with carb cleaner, blast the bugger with compressed air & rebuild. Replace all fuel/air hoses and strip/rebuild the filter. Make sure everything is air tight & spotless. Check the admission pipe for cracks, empty the fuel tank, clean it, put a petrol filter when you replace the fuel pipe and put a new filter in the air box. It's often the little things - good luck.
Thank you for all your help im one happy chappy ish i still hate the dam thing iv taken it to bits more times than i care to remember. -.- But i striped the carb cleaned it with the carb cleaner left that to soak for about 30 mins. Put that back on the air box seems fine so i left that same with the fuel line all seems ok. Then i found the problem a really dumb moment on my part the rubber from the spark plug socket was still on the spark plug. So it was misfiring duh! so after that i put it all back together took it for a drive and it wouldn't go over 30 at this point i could of tossed it in the lake. I found out its a restrictor in the exhaust so i took that out which took some doing i snapped a stud putting it back on but now its running better than it ever has fingers crossed it stays that way
If you de-restricted the exhaust - check your carburation / plug colour. Might need a richer main jet.
