Chainsaw Repair

so far, the car/truck plugs show the leanest and thinnest rings.  water cooled, different animal.  settings for maximum fuel efficiency/lowest emission.

for max power, have to believe the rings would need to be a bit wider, but how much wider?

not enough samples so far to make a determination, imo.  not sure if one will even reveal itself.

need more used plugs to cut up.  chainsaw ones. 

going to give my friend a call who has 3 or 4 crews to see if he could help me out with a pile.  he usually de-carbons and re-rings all the saws during the winter months when work slows.

maybe with 50 or so cut plugs?  cutting only takes a couple minutes per plug.

if anyone would like to contribute some plugs to the effort it would be cool.

thanks

chart.........so far.

not enough data for the saws yet.

but with 9 sample plugs for the car/truck......the range can be seen.

the "mean line" for each is the average.

will fill in as time goes on.
