My bit was to high.
I now use a strip of lexon to make sure its proper.
I put the lexon strip between the com and the bit. When I tighten it up till the bit touches the lexon the strip will lean forward on the top side just a tid-bit. This shows me that the bit is just above TDC. If its leaning to much I drop the bit down, not enough, bring it up.
I will get some oil and try it your way. Any recommendations on oils to use?
