[510-Gem]

So the initial problem was solved with a thorough carb cleaning and the sled has since started flawlessly and will idle all day.

What I have been finding recently is that the machine will run fine for about 3-5 minutes after a cold start, but then starts to bog down when I’m on the throttle. It will putt along at about 20-30 km/hr but any more throttle and it really bogs down to the point of not going anywhere, but the engine still fights to stay alive. Adding a bit of choke kills it outright. I have changed the spark plug and the problem persists. I’m wondering if it is a belt issue, and once that belt heats up after sitting all night it stretches out and effects the clutching. Thoughts?
