I have been fiddling with my first 2-cycle engine, a gift leaf blower. The obvious problem was the pullcord was broke. Now that that is fixed, I find that I can't pull it very easily. When I pull the spark plug out, it pulls great (and I get spark! yeah!). I also covered the plug hole with my hand to make sure the plug wasn't the problem. It wasn't; with my hand over the sparkplug hole, I couldn't turn the engine.
So I'm thinking that something is wrong in one of the valves and it's not opening. I pulled off the carb and can see straight into the cylinder and watch the movements. I didn't go so far as pulling off the exhaust yet.
Everything is beautiful and sparkling. But I'm thinking that the pullcord broke Because of what ever is going wrong with the engine.
Any ideas on why it won't turn with the plug in, but will with it out?
