I picked up a 77 moby 50v. It came with an old cdi and what looks like a new SHA 15 carb with a 66 jet. The cdi uses the original cream colored Novi HT coil. I cleaned out the carb and put in new gas. It gets a ton of blue spark and the spark happens what appears to be about 10 degrees before TDC. The exhaust is not clogged. The compression holds at 90 psi all day. The plug is a little wet when I remove it after spinning it over with a drill. Gas drips out where the exhaust is screwed in when I am turning it over. It won't even sputter, nothing. Plug comes out is is a little wet but not brown or anything - it still looks like new. Nothing happens when I put gas or starter fluid directly into the cylinder. Does anyone have any thoughts?
