I did another re-check on the magneto and it is working fine-without the killwire attached! Mowernut and fast Grass were right. So I was back to the original problem. It starts then stops. I've done the Clean carby dance again and again. I noticed a little black stuff in the bowl from time to time. I decided to have a look at the fuel tank (plastic). The photo
shows some of what came out.[Linked Image from img594.imageshack.us]
It's like a black crystal. It must be the fuel tank wall.
I thought my problem would be solved but there hasn't been any change. Starts and stops. Do you think I will need to do this again? There is no fuel filter anywhere on the line. Is it OK to add a filter or does it interfere with the gravity flow?
