Re: (ET) Power Pulse Required Most of the Time

[Christopher Zach <cz alembic crystel com>]

I would guess the centrifigual clutch on the end of the motor is broken. 
That allows that type of trac to go into 2a/etc, and the power pulse 
switch bypasses it.

You could always bypass the clutch, but that was to keep the tractor 
from popping wheelies or something. Never saw a need on an E20; the E15 
uses the SCR's as delays.
