Hello George Marsh, .003 is NOT enough. Set the intake at.006. They have a tendency to get tight. @.003 won't take long to go to zero,

Looked up clearance on a briggs sight, .003 to.005. Some recommend going a 1/4 inch past TDC. I've always used TDC, except for today. Going to set it at .005 TDC and see what happens. However on older models it shows .004 - .006. I've always found the clearance increases, then the decompression valve doesn't work. Come to think of it, because the cam in new, there may be more decompression than needed, so I may have to go past .006. Starter spins the motor over like there is no spark plug, very little compression. With the bad cam, motor would lock up it had too much compression.

I'll play around with until I get it to work.

Have a happy new year.

Hello George Marsh,

The 1/4 in past TDC insures that you have past the compression release,

You can feel the compression release. Piston is about half way up the cylinder. I'm going for TDC. Let you know what happens tonight.
