I put an electric starting system on both my T 20's. I used a Honda starter and a Toyota flexplate. The flexplate is mounted behind the damper pulley using three bolts through the slots in it. The starter is mounted using existing bolt holes, and two homemade brackets. I added this system mostly as a novelty, as both tractors start the first or second 'click' of the mag...Did they ever put an electric start on these things?
My thermostat was rusted stuck horribly. I replaced it with Mazda 929 therm using a stainless plate and flathead screws in the existing 1/4" holes. Note that the washers are counter sunk and the edge of the washer has to be ground off to clear the outer housing.Hey, how 'bout that thermostat!!! Must weigh 25 lbs!
