Rare Scottish Tree Badger Posted July 9, 2005 Report Posted July 9, 2005 ok, so my compression should be close to that? 390317[/snapback] At your altitude (1000 ft) on a fresh bore you'd be looking at around 125psi. Don't pay too much attention to the actual figure that you come up with unless it's much lower, but what you don't want to see is a difference in compression between the two cylinders of more than about 10%.

Rare Scottish Tree Badger Posted July 9, 2005 Report Posted July 9, 2005 when it was running fine it had just as much power as ever. 390407[/snapback] I don't doubt it. ... I've only gone into detail about the air as you asked "what's that for?" about your altitude. ... It's allway's good to know what your compression is at as a reference for the future. As others have pointed out, your problem is likely to be jetting or an air leak. But jetting at sea level is very different to jetting at 5000 ft above, which is why you needed to state your elevation. It might also be a reed problem that only shows up at low RPMs. ... The compression test might show that one up. Another point about the air is that it also gets thinner as it warms up. ... Just to confuse you more! Rare. Quote
