I have flail mower with this engine:
15 hp 420cc JiangDong electric start
That engine is basically Honda knock off.
Everything worked fine till today.
I towed mower out into the filed, started it, start mowing - after about a 100 ft, it dies. Engine shuts down. Start it again - starts fine. Start mowing - engine sputters and dies.
And keeps doing this - starts, runs fine, start moving, what means - mowing - engine dies. Dies like as if fuel supply cuts off. But don't listen to me.
I tow it back to where it normally parks, check on every thing - all appears to be fine. Start, stand there for few minutes - runs fine. Start towing mower - dies. Starts and starts dying - so on a hunch, I opened gas tank cap. PRMs jump up, engine appears to run fine. Put cap back on - engine dies after some time.
So out of desperation, I leave gas tank cap not fully tight - mower starts mowing. Sounds abit strained, I just go slow, but it mows. Didn't stall even once. Gas cap undid itself several times during 1 hr mowing, but, otherwise, I finished what I needed to do.
Parked mower, tightened gas cap.
So I figure, it has something to do with fuel supply?
Air filter is clean.
I had tank topped before I started mower, but I had same last time, without any problem. Does it have like a fuel pump or something? Or it's simple gravity feed into the carburetor?
Gas tank has cap and what appears to be fuel filter at the top - black flat plastic piece in rubber grommet, with barb for the fuel line. Fuel line is not pinched. I could not pull that piece out, I tried. Thought, maybe filter got clogged...
Any ideas? Of course, I sold my ZTR last week, confident that I have running mower and, surely enough, here we go.
Thank you.
