My views on techumseh:
Ever since my teens, I knew they would be the first to fail, and hated working on them. From lawn mowers to tractors, carburetors were an epic failure from the 70's till their demise. On kohlers, you set the carb and forget it, unless of course you mis-treat the fuel system. Techumseh, you set it, and set it, practically every month. Accidently store your snowblower over the summer without properly conditioning your fuel or draining every last drop, and you will be in for a total carb rebuild come winter. This will sour an end user and make them avoid the engine at all cost come next equipment purchase. It is a shame as the actual engine itself was very competitve and very robust.
I can;t remeber ever adjusting any of my kohlers and they just sit with fuel all winter. I just had to clean a carb on my generator, but it sat for a very long time with stale fuel and it varnished.
I wonder if you could get an adaptor to put a differnt carb on the techumseh.
