Hi,

I have a problem tuning a Ryobi 31 single ring.

It has CH electronic ignition.

It starts fine, ad runs about 5800 rpm with 18 X 10 prop, but runs for about 30-45 seconds, then dies.

I remixed new fuel, charged ingition battery, and still the same thing. I know it is getting plenty of fuel.

Could it be getting hot from a timing too advanced perhaps? It ran fine on the bench with the ignition, but I have since had things apart and back together.

Also, on the stock carb, where should the needles be? I think the low end is out about 2 turns or so, and the high end has been in and out trying to get it right, to no avail.

any ideas? I'd love to test fly it sometime

thanks

Bill
