good idea on electric shutoffs.
I thought about adding one to mine.
but too lazy,
figured they would be like the gas cutoffs, in time they wear and will not cut the gas off to carb.
then its a drain tank and replace cutoff and they are like the carb kits of today, no longer the quality they used to be. one time I got the third one before I got one that would seal when cut off. may have been a bad batch, I try to buy the best one I can get.
like most things for our old tractors, made across the big waters.
