thanks maxwestern, too easy, $15.

mower did not want to kick over with the spark plug in it, will look at the valve lever settings again tomorrow. I will use the screwdriver method for tdc and in 1/4"
it is either that or the decompression in the crank case area. I suspect it has more compression than before with the valves lapped and will have more power.

ps the $50 digital tachometer worked, but no batteries included, nothing in the manual on what batteries or where to put them, barely worked with fully charged rechargeable AAA's, and the manual mentioned recalibrating every 12 months, but nothing more said on how or where to do that. about what one would expect. but at least this time I did not break any bolts.
