At our update seminar we were told that the 261,362,461,201 and more models will be going to the M-tronic set up. NO release dates were discusses. The 261M-tronic is already in late test stages in the field. I think you will see the M-tronic even make it's way down in the farm and ranch saws. It helps meet epa standards and helps protect against some to the crap fuels you see in the market.
Another interesting point of discussion was the folks who are using 87 octane may actually be using 83 or 84 octane fuel after the alcohol evaporates out of the gas. Also the white residue you are seeing in carb screens is a olefin polomyer used in the refining process today, it is creating a waxy residue clogging inlet screens creating lean conditions. If you don't have a ultra sonic you want to make sure to replace the inlet screen on every carb rebuild along with the fuel filter.
