Default hard start warm or cold ???

I have a G1 and have had alot of work done with no results!!.
1. reed valve gasket replaced
2. new carb
3. new plug
4. fuel filter
5. new clutch side crank seal
6. compression test (115-118 psi) with muffler on or off
7. BBQ muffler
8. new air filter
really baffled after cranking for a minute and playing with choke, it starts and then only run good with a quarter choke on? Runs full speed and seems ok but if you stop, you go through the same process to get it going again????
Any suggestions what I can do next. One guy said it has to be a vaccume leak somewhere??

You need to get fly wheel seal changed and go from there

Is it easier to replace flywheel seal by pulling engine or putting it in with the engine in the cart???

It would be easier out of the cart but it can be done in the cart

I have started the process of replacing the flywheel side crank seal. What is the best way to get the nut off of the plastic flywheel?? Is there a trick or certain way to do this without destroying anything??

started the process of replacing flywheel side crank seal. as soon as I took off the cover there was oil on the bottom! Looks like the seal has been leaking a while! Will update when I start putting it back together.
