Mtronics seems to be doing a pretty good job at 32to1

Is that 2 stroke or 4 stroke?

I would say the 241c mtronics burns View attachment 421572 the 98.5 race fuel and the 32:1 r50 just right?

it's burning clean but with a ecu controlled carb good gas and good oil at a good mixture i wouldn't expect any problems.
that plug looks like my plugs after 30,000 miles inside a f150.
i suppose the economy is quite good with this saw also.

Is that 2 stroke or 4 stroke?

its a page out of my haynes small engine repair manual for 2 strokes and 4 stroke engines.
the book is old and dated but still holds good value.

Just spoke with a Motul Rep. He recommended 800 off-road or road racing for my ported 660. He didn't recommend 710 but stated if I wanted to try 710 use only at 32:1. It's only 75% oil! He also said 800 could be mixed at 40:1 with sufficient lubrication. Guess the other Motul guy I talked to was a sales rep. I asked about the JASO rating of 800. He said any oil made stricly for racing isn't JASO required but it would exceed FD certification. Using 800 or R50 I don't think we'll ever have a lubrication or wear issue.

I thought ash was whats left over after I burn wood in my fireplace.

this is what poor quality oil will do to a 2 cycle.

I bet with more fuel run through the electrode white part will gain some color ,looks good though to me .

Ya the last 6 cuts were consecutive and wide open then I killed it after last cut

my lawn boy 2 cycle plugs are blackish grey but if the engine has a decent load the plugs clean up a little.

Thats a good answer ,but i still do not know what ash is ,

ash is a measurement of residues left after burning.
ash is what makes up the solids in smoke and can contribute to hard deposits.

So it's just like wood man heh

75% oil. so at 32:1 of 710 it's actually 40:1 ...why he said run at 32:1.
