Thanks.....I think I am just going to break down and take it to the shop......Sick of throwing parts and nothing sticking Replace everything from the tank to the engine with new parts made to withstand ethanol fuel, then attack the root problem: Your carburetor is full of the goo that hardens.... from the use of ethanol fuel. After you get it fixed, never burn ethanol again. Also, if it is a 2-stroke, ethanol in the fuel can not only cause phase separation, it can actually cause the oil to come out of solution with the fuel... so your engine can seize, due to the fact that it is oil starved. |

Interesting never knew ethanol can cause the oil separation. I have replaced Tank Lines Filter Fuel pump Water fuel separator so I know it is the carbs at least I think it is.....Gonna take it have the carbs baked and cleaned and see if that fixes it.....Compression is still good and have strong spark so I know it is in the fuel system.....I only us ethanol free but I am not sure what the previous owner used....also put sea foam in last time I worked on it and did not seem to help |
