Re: 1940 110 Compression

My 38 110 ran very smooth but had low power and a hard hot start issue.Compression was @70 to 75 psi cold.After adjusting the valves -power was much improved and the hard stating was a thing of the past.
The service manual says to set the valves with the engine running and warm to .05 int and .010 exh.I found this almost impossible with the exhaust manifold hot and in the way of the center cylinders.Now I found out you can set them cold to .07 int and .09 exh.Removing the spark plugs, right front wheel and inner fender is a must.I didn't run a second comp test,hind sight indicates I should have.
