Tecumseh Engine Throttle Control Knob

thingiverse

I need to replace the broken knob on my snow blower, so I'm looking for something that matches it closely. Ideally, I'd like to find an exact replica, but I'll settle for one that's very similar. To make sure it fits properly, I'll print out a new knob upside down and check its dimensions. Once I have the correct size, I can move on to the next step. Before attaching the new knob, I need to heat up the motor throttle metal arm with a lighter for a few seconds. This will make it easier to insert the knob into place. After heating it up, I'll simply plug in the new knob and give it a try. It should fit perfectly once it's been heated.
