Factory setting say intake 0.004
And Ext at 0.006

I just reset the at .002 intake and ext at .003
Starts easy now.

Do I take it you can increase torque by play
With your lash? If so which valve lash should I play with.

I also put a alliunium flywheel on the motor
Due to the cast iron one one the motor was Chinese
Do you thank a bunch torque will loss now.

That may be to tight? Might screw your cam up. Hopefully a more knowledgeable person will clarify

Too tight will round off a lobe, factory valve settings are around .005-.006

So set both valves at .005 when I set them before I couldn't
Start the thing.

The surfaces on your cam that look all crazy that tells the engine what parts to move and how much. I'm sure there is a better explanation. But I'm sure you get the point
