87 carby tt350 problems

Gday guru, I was given a nov 87 tt350 and it appears to be having carby problems. It will fire on 'start ya bastard' and has a very strong spark and good compression. I do not have a manual or the money to buy one at $70 plus. It will hopefully become a project to re-birth into rego over time, but want to get it running properly before spending any real money on it. It has had a recent kit put through it by a shop mechanic, the float/needle and seat may be wrong in assembly. Currently the float is contacting the needle but I think it may need to be placed into the fork of the float arm assembly. Please advise of trouble shooting options and/or fixes. Cheers, Kev.

Hey man,
I had a similar problem and worked out that the timing was out.Check the valve timing as a worn camchain can force it to jump a tooth or two on both the intake cam sprocket and exhaust sprocket.This problem assimilates as a carby problem.

Pull the carb off.Take the bowl off,take the pilot jet( the small one )out and clean ALL the holes out where you can see through it and the side holes.Then take out the main jet and make sure it is clear.Reinstall every thing and dont bend any parts on the float or the needle vale.
