Spark can not start the unit, rebulit carb, but it seem to have weak or intermite spark,

Ron, the excessive gas could be the result of continued start attempts with a weak spark or a bad plug or a carboned plug. If none of the carb adjustments have not been turned or twisted prior, I'd suggest obtaining a fresh spark plug. Make sure the gap is correct. Blow out the cylinder with compressed air to vent all the residual gas/oil within. Ground the new plug against the engine and pull the cord. You should observe a fairly bright spark at the plug. If no spark you could have a faulty coil/ignition module. If a bright spark is present, install the plug and give it full choke and attempt to start. It should attempt to start within a few pulls....when it does, go immediately to HALF-choke and pull again and it should start.

check gap on coil the gap on the points and also make sure the magnets are free of rust, the capacitor could be weak also.

did you change the distributor or just the cap?

first check your compression....if weak...could be a few things to look for...valves not closing...timing...

Start with a fresh spark plug. Part of the spark may be traveling to ground via the carbon deposit on the ceramic electrode insulator. Drain the carb; condensation in the gas tank may have built up in the carb float bowl. Engines don't run well with water as fuel. While servicing the bike, clean the air filter and lube the cables.

take a blow gun or compressed air blow through carb where the fuel lines go & then try it

If you have 2 carbs that work on another unit but not this one then that narrows down the fuel problem to either an intake/ vacuum leak or bad fuel in the tank.
The compression sounds a tad high which could indicate valve timing ( exhaust opening late or not long enough)
On the ignition side you could have a bad CDI , weak pulser coil or sheared flywheel key.
I believe I would lean toward suspecting the ignition. I had a Honda that gave me fits acting like a lean issue. I was in that carb 25 times if I was in it once. Same thing, idled fine but died on acceleration. It was the CDI. Put a spark tester inline with your spark plug and see if the unit dies due to lack of spark.

If your side stand switch was bad, it wouldn't run at all. I would suspect that the coil is breaking down, and would need replacement.

YICS ignition is very voltage sensitive.... meaning no battery charge operation means poor ignition.

sounds like the carb wants cleaning and re-balancing
