Last snow, the electric starter on the snowblower wouldn’t engage. It would spin, so the motor is ok, and the blower starts when pull started. Its 5F out, 35F in the garage.
I read somewhere that the mounting bolts can get loose from the vibration, causing the bendix gear to not engage. Description fits the symptoms, so let’s dig in.
Removing the shrouds and gas tank, the starter was “loose”, kinda rattling around. But the four mounting bolts are tight.
Removed the starter, found the wire to the lights is rubbing through. The heatshrink I added a couple winters ago is rubbed through. The factory wrapping is also rubbed through. The wire insulation looks uncompromised though.
Starter has a mounting plate of 1/8” steel spot welded (x4) to the case. Two welds are broken, the other two are breaking, so the starter wiggles on the plate.
The factory shroud has a hole to route the gas line and wires through, but another shroud blocks it, so everything gets pinched against the starter. I trimmed the hole bigger on one shroud, and opened it up on the other.

Welded the mounting plate to the housing.
Added some more wrapping to the wire to the lights.
Added more protection by using a piece of fuel line.

Re-installed the starter. Cleaned and lubricated the bendix gear mechanism.
Reassembled everything and tested. Back to service, ready for the next snow storm.
