Ok, I bought this off someone up here and it won't start. It sounds like it wants to but doesn't. I figured it was a bad spark plug so I bought a new one and the same thing happens. It just cranks. No spark I guessed. When I take out the spark plug, it almost sounds like it's gonna start (better without the spark plug) but of course it's not going to without it. Anybody know anything about these or have any ideas for me? Any input would be great. Thanks.
