I rebuilt the TSX-662 over the winter along with a lot of other repairs at the same time. New manifold, elbow, exhaust, fuel line, repaired fuel tank and more.
The carb was rebuilt with a new float, which I set as the instructions said. New throttle shaft, seals, and everything else that came in the kit.
First question I have is, should the tractor start and idle with the power jet closed completely? If I close it, it stalls every time. I have the idle jet set so it idles smooth with no black smoke.
Second, While trying to get the power jet tuned (I can't tune it 100% until I can move it out and put a real load on the engine) I'm having lots of issues with it stumbling and backfiring. I can rev and hold it and it runs fine, no overheating, etc. However, opening the throttle quickly almost every time it will pop through the exhaust and carb.
I put my dwell/tach meter on it and idle seems to be around 475-500, a little high, but not too bad. The timing was advanced a good bit, so I backed that off to 5 degrees BTC at idle.
I also noticed fuel leaking from the power jet adjuster/needle. This wasn't replaced in the rebuild, so I am ordering a new one.
There is still fuel leaking from the carb inlet when it sits with the fuel on and not running. I'm guessing that maybe I have the float adjusted a little high, but I'm open to other thoughts there.
