Ok I will try the penetrating oil.. personally I’d rather work that trigger for hours than pull the flywheel, I’ve done it in the past and it creates such a issue. usually they just WILL NOT release. also the weird plastic thingie that hooks the linkage to the trigger plate (timing linkage?) is weirdly loose and doesn’t hold the linkage very well, any pressure and it falls down and out .. is that normal? circled:
otherwise I will pull the motor, I have one mystery water leak near this thermostat assembly under the motor shown in the attached picture of a similar motor.
my question is.. does the thermostat (when hot) allow water to “A” Drain down from the cylinder jackets, or to “B” travel up into the cylinder jackets… the only thing that makes sense to me is “A”.
