Well, I finally went to break in my O.S. 21 VZ-B engine yesterday and as expected the starter box would not turn it over. It started to at first but then just seized up. I heard that engine is very tight and man are they right. I was thinking of taking the glow plug out and putting some 3in1 oil in there and try to just spin it over like that without the glow plug in just to loosen it up. Will this hurt it? Thanks in advance.
