I've serviced many (many) more R-Tech powered blowers that ran just fine after being cleaned up. I do believe, however, that it’s worth a person’s time to hunt down something powered with a two-stroke Tecumseh. Only a couple R-Techs and a mess of Tecumsehs have come in with regular or too lightly mixed gas in the last couple years. You can usually rock the shaft back and forth and get those freed up. I've got two (R-Tech) blowers behind my garage now with thrown rods. Don’t despair. My stats on R-Tech are in the dumper because people seem to bring their stuff to me when their machine has one or both feet in the grave. R-Tech powered blowers have been a gold mine for used parts. Kind of like AYP/MTD mowers are a great place to harvest good B&S engines. I save people quite a bit since I don't charge for used parts. Tomorrow I try to transplant a 4.5 HP Tecumseh from an MTD blower into a Toro with a blown R-Tech. Probably won't fit. Make everything just different enough so it won't work on anything else... Anybody hear anything on when the people who bought out Tecumseh are going to get their Chinese factory going?
