I have a Benelli Blazer (circa 1975ish I think). It cranks, but smokes like hell and isn't getting revving as high and when I let it sit there running at full throttle it kinda revvs up and down. I just cleaned out the carb, put in a new plug (anyone know the correct gap, i just used what the old one in it was set too). I drained the tank and also used a mix of 43 to 1. I also put in some trans fluid but I think I put too much, not sure.
this thing is in awesome condition for its age with a little more than 600 miles on it, and I would really love to get some use out of it, any help would be greatly appreciated
