re-ringing a B&S engine

Has anyone done this? I bought a rotavator with a 3hp I/C engine which has low compression and only starts by squirting some oil into the cylinder to raise the compression. I was thinking about buying some new piston rings and fitting these after giving the bore a bit of a rub with sandpaper to remove any glazing. Does this sound like a feasible plan? I don't want to spend too much money on it as it won't get used a lot. Where is a good source for the new piston rings?

I think you're right, probably better to just get another engine rather than mess around with piston rings that may or may not work. Mines a fairly recent engine, so could swap over most of the other bits. Luckily there's a couple on ebay near me so I'll give that a go. Shame really as I love tickering with things

Stalling could mean the clutch needs adjusting.

hi if you want to try and get compression up on spare engine you could try a product caled  engine restore  change oil then add engine restore it makes a seal in cylinder jezza
