Here are my problems...

1) It won't start in neutral and seems to be either flooded or overloaded with oil.

2) I have to advance the throttle lever to medium/low throttle (with side button pushed in so it does not go into gear) for it to start

3) I have to keep it running at medium/low throttle until the gas/oil burns off (say for 15-30 seconds) with a lot of smoke .

4) The engine dies if I pull the throttle back to idle position and I didn't wait until the heavy smoke stops coming out of the exhaust at medum/low throttle.

5) All six spark plugs are equally very oily when I remove them.

6) There is an accumulation of oil at the bottom of the cowel below the carbs, as if oil runs out of the carb barrels when the engine is tilted forward.

This was taken from

hkeiner posts..​

However plugs 3&4 do build up carbon and 1&2 do not. I was wondering about crank seals.
As I said been chasing this problem for years.....
Any thoughts!
