Sven,
How do you check that?
I did put in a new carb kit but there wasn't much to it.
I'm guessing you are referring to the main piston in the carb?
I did in stall a new seal and pin on that so they should be functioning.
I put on a new non-resister coil and re-attached the ground to the motor (which was off when I got it).
I have not been able to confirm but suspect it still has a hot start problem.
Other than the above, I have not been able to check on the voltage questions yet.
Thanks All!
