Haven't checked reeds but exhaust is backfire. Put rag by exhaust and it was spitting oil. Plugs were new and after 5mins are wet and black

Take dpm out, take it apart and wd40 it

Used 9 volt battery to activate it back and forth

If dpm is stuck, or quits it goes full rich

took it out and blasted it with wd40 and tryed to hook battery to it and it didn't move. No sound no nuttin. That mean it's toast? Or should I be able to see movement in the lil brass piece?

Also forgot to mention that when it started back firing I pulled the exhaust side cover off and noticed my oil level went right down to the bottom line. Fired it back up moved it 10feet and checked it again and it was back to just under full. Where did the oil go? Bottom of crank then push back up? Is that normal?

Ummmmm, that's weird

How bad did it smoke, cause if crank was full then it would almost hydro lock lol

Doesn't look oil, looks fuel

Light it with a lighter and see what it does

Changed out DPM just now and started off ok, the. Right back to back firing...shut it off for a few mins and started it and sounded like a gun shoot backfire....

Ballzdeep · Feb 11, 2018
