The first time or 2 I tried starting it on Sunday, It ran for 15 seconds then died. That was full choke, full throttle, 3 pumps primer. Fuel petcock is open, as I didn't turn it off when I put it away 2 wks ago.
Then I tried starting it to the point the safety cutout for the elec starter came on. No running, just tons of backfiring. So I took carb cover off and then pumped primer again to be sure fuel is flowing. Yup. If I pump it twice or more fuel drips out of carb mouth. Spark plug is new, but I dunno what correct gap is supposed to be, nor do I know for sure if it's the correct plug for this motor. It was wet with fuel. I cleaned the electrode up with a little sanpaper. it had no deposits on it, but was black, i am assuming from running a little rich the last 2 times I used it (and those times it ran great).
To be sure I had spark, I unhooked plug wire and tried starting it. Nothing at all. As soon as I hooked plug wire back up and tried starting it, it began backfiring again while I try to start it, but won't start. I searched online then, and found the settings for the jetting adjusters, and set them both at 1.25 turns out, then tried 1.5 turns out. Still wouldn't start. So I turned the throttle down, and choke to 3/4 closed. It started right up and idled low for about 30 seconds, then died again.
I tried again and again after that and it never started again.
So that's where I am at right now. I will check the comprssion like you said tmw, and try to restart it. I will add fuel line antifreeze to it to see if that helps, but I don't think it's frozen as my fuel lines are new (2 wks ago) and filter too, and they are all clear and I can see fuel flowing through them.
the diagrams posted above are what my carb appears to be (judging from the outside appearance of my carb-have not disassembled it yet to be sure), so that possibly will be my next step. Anyone know what Bosch plug I need for the machine? And the gap? Thx guys.
