Ok so the post hole digger saga continues. The 2 post hole diggers got pinched out of his trailer so I got him a new one from ebay. This one worked sort of ok, I think it is probably a bit underpowered, and a few weeks ago he brought it back because he couldn't get it started. I put a new carby on it and it fired up fine. I started it up half a dozen times and it seemed fine, then after I had given it a rev I let it come back to idle and it stopped abruptly with a noise that didn't sound good. I have not been able to get a peep out of it since, it has spark, but I'm thinking the flywheel key may have sheared and the timing is now off. Any other thoughts?
