Model 12F802 Type 0875-01 Code 95082359
When I changed the plug and it did run a little better but the light popping sound was still evident once the engine warmed up. So I went on to remove the exhaust and checking the tappet clearances.
Exhaust - .15mm (.0059inch�s)
Inlet- .04mm (my smallest gauge) fit in however not all the way. � (.00157 inches)
I was very careful with my measurements and ensured both the inlet and exhaust clearances were measured with the engine a smidgen before TDC.
I would like to clarify the engine now starts on first pull and runs pretty well. It idles nicely and has smooth full speed. I have not put the engine under a heavy load yet.
Like I said I haven�t pulled valves out before however I have watched video�s of the process that included valve lapping and grinding.
I await your thoughts.
