Hi.
My first post here so please be gentle with me ;-)
Bought a tw125 a few weeks back and I'm really pleased with it. However it's just started mucking about. If anyone could give me a couple of pointers I'd appreciate it.
I'm suspecting a carburettor issue.
Once started it runs great. Starter motor turns over fine. Good compression, there's a good spark and I can bump start quite easily. It doesn't idle correctly - either running too fast or too slow and thens stalls. Once it stalls, it turns over but will only fire after a long struggle!
I have had the carburettor apart and the starter plunger was a bit stiff to get back in to the housing so I'm wondering if it's not seating correctly? I'm also wondering if the throttle is sticking open slightly? I've cleaned it out with carburettor cleaner but I don't have an airline to really blow it out properly.
Is it worth persevering with the carb or possibly look at something else?
