My MB35 is running like shit and I cant keep it running. Changed all the fuel lines got it running but it surges up and down and back fires once in a while. Been sitting for amonth ran fine last time. I run the gas out of it every time. Seems like when I took the filter off it runs better but when I put it all back on it floods out. Any suggestions?

When was the last time the carb got a cleaning? That's probably where I would start if a new fuel filter doesnt solve the problem.

idle jet was clogged...I just cleaned it not that long ago. Damn ethanol ruins everything. Im going to start running non-ethanol gas.

Yep, it sucks. Non-ethanol premium is better, but you still need the put Stabil in it to keep it from breaking down so damn fast.
