looking for a crank case gasket for an rv175.
Greetings,
I would like to know how I can buy a Rato RV 175 motor / electric starting
Looking for a diagram to adjust the governor on this thing and to either replace/upgrade/or repair the current carb because the thing just turns fires up, and shits right back off. And I can’t find any parts or info for it. Any help?
