Thanks for all the helpful replies .
I will look for a decent carb.
I will also do a compression test.
I have a feeling that something I did too the wiring is also causing an issue, although there seems to be good spark.

Hi all
Some help please.
I have researched the threads ,but still a bit stumped.
Can someone tell me what size the factory carburetor is.
I'm trying to get a project bike running,I suspect the carb is way too big.
It's a mikuni TM slide valve carb.
The intake bore measures 34 mm
The air cleaner side 60 mm.
The bike did actually run , although poorly,it was ok at wide open throttle.
I did some work to the wiring,(stripped out everything except the power to the cdi and coil ,it's on a kill switch)
It won't start now ,there is spark.
I did bend the needle by accident when I re-assembled the carb ,so suspect that's not helping ( I straightened it as best I could).
I'm looking at the cheap aftermarket carbs on the internet,any suggestions.
Many thanks to all.
