I was working on my friends eton 90, but we cant seem to figure out whats wrong. It runs only at full throttle, once you let off it will stall when you give it gas, when running it puts out blue smoke. The oil level is low, is there a way we can check the jetting, and block off the oil tank and add mixed gas from now on?

 

If you quit using the oil injection be prepared to rejet. Check the easy culprits first though. How are the reeds? probably not them, but hey, might as well look [img]i/expressions/face-icon-small-happy.gif[/img]

 

Try steping down the jetting a little bit on the pilot or needle circuit.

 

eton... hahahahahahahhahahahahaha
