Have a Stihl BG 55 handheld. Has plenty of compression good spark with plug out. I CAN NOT GET IT TO FIRE FOR ANYTHING with plug in!! Anyone know how to properly set the gap on the flywheel and ignition coil? Also I am thinking that maybe the flywheel key spun? I am trying to start with starting fluid... sprayed a lil in plug hole-nothing sprayed a little in carb throat....Nothing. No Fire either time Cleaned carb. I am going to dump the gas and ad fresh 93 50:1. running out of ideas... Any suggestions How do I check/set the flywheel timing? It appears to me that Stihl USA locks down the PDF repair manuals tighter than the The National Security Admin. /NSA. They want us all to go to the dealer/steelerships Maybe I will call Wikileaks.
