Bruce, Have you checked to ensure it has spark after it stops?  Once warm it is possible for a coil to fault but still be OK when cold. Also, on these small engines everything is so tiny in the carburetor.  A tiny drop of water that finds its way into the filter or carburetor can cause problems.  SOme fuel screens are so fine that water can block them.  While this my sound heretical, I actually find a ethonol gas great in small 2 stroes early inthe season when you are sure to use all the gas up in a month or two.  It will handle a bit of water in the system and keep on going. I'd try putting a few Tablespoons of the Red HEET, (Isopropyl alcohol) in the fuel.  It mixes with both the gas and oil and can help clean out any moisture. In a climate with hot humid days and cooler night it is hard to keep moisture out of an unpressurized fuel tank like those on the engine since they will breath the humid air in and out as the temps change and some water can condense in the tank.  ALso, if your tank cover has an air vent that closes be sure to close it when not in use and be sure to open it when starting the unit.  If you didn't open it that could also cause it to starve for fuel since I guess it is a gravity feed system. All the best, Gary Hagstrom

Thanks, I'll check them out. lots of good suggestions.. will be on it this weekend.. maybe with a followup report On Thu, Jul 9, 2020 at 4:01 PM Gary Hagstrom <ghagstrom@yahoo.com> wrote: > Bruce, > > Have you checked to ensure it has spark after it stops?
