Re: Can not get this 18 running right.

It sounds like you may have a leaking seal at the top of the crankshaft. The symptoms you describe could be caused by air getting in thru a worn seal which is a common issue with these motors.

To check for a bad seal, I pour a bit of fuel or oil on the seal and turn the motor over by hand. Any bubbles coming up lets you know it’s time for repairs. While you have the mag plate off, you might also want to give the points a polish to remove any buildup from sitting for so long.

Here’s a short vid showing how I do it.
