I have a real head scratcher, 85 22R was running great. My son was driving it and called me saying it was losing power he couldnt get it to go over 40 mph. I told him bring it home, The next morning I went out to start it and it turned for a bit then started but was loaded up ( sputtering and I could smell fuel ). I turned it off and now it just turns wont even start for a few seconds. I checked spark and its ok, put fuel in the carb nothing, pulled the dist to make sure it didn't jump time that was good. replaced the fuel pump and filters, wires, plugs, coil, ignighter. Im lost anyone have any idea's ?
