I posted a little bit ago with a wiring problem that I believe I have figured out, but now I have a no spark and I believe too high of a compression problem. It is a 422707-1214-01. I put this engine in to replace my old one that threw a rod and the guy I bought it from said it has been sitting for about 2 years. I know the battery I have on may be too weak to start it, but I have also tried jumping it with my truck and a battery charger with engine start option. It doesn't even get one turn before it stops. However, it will continuously crank if I take the plugs out, leading me to believe there is too much compression. From everything I have read on the internet, it looks like my valves need to be adjusted and I'm not sure if I'm up to that process myself. Depending on what you guys think it is, I may just bring it to an actual small engine mechanic. My other problem, is I tried checking the spark while I had the plugs out, with the wire hooked to it, touched the bottom of the plugs to some metal on the engine and no spark. The ignition coil and plugs are all new, I gapped the armature with a folded piece of paper, and took all the rust off of the flywheel. Any input?
