Well that was the problem you went over my head....LOL.
Don't blame you on that attitude. Here nearly every Tecumseh that comes into the shop needs parts that are no longer since they went under in 2009. Most of are on walk behind mowers so the whole mower is usually killed off. Usually even mower body are too far gone as they are cheaply made in the first place. I think only 2 push mower this year. With the current market here it is just as cheap to replace as it is to repair sometimes even cheaper.
Well I going back back to hug my heater as it is time of year here. We went straight from Summer to Winter I think as it was 85F last week and tomorrow high will barely make it to the mid 30's F. They are even talking snow flurries.
