If it starts on spray down the the carb throat and can be kept running for a minute or so with repeat SHORT shots down the carb then you have a fuel supply problem which includes a big air leak. How serious is this?Ģ) I checked the spark plugs, it looks okay, also I thought if I can start the engine with starter fluid, the spark plug in theory should be okay?ģ) the carb choke closes but not like a perpendicular (complete?) close in the carb, is this normal? It closes with a slight slant.Īny ideas/help would be appreciated. I am now out of ideas what's causing the engine not starting.ġ) the carburetor gaskets are out of shape, 2 of them are slightly teared when taking them from old carb to the new carb. I was expecting the engine to work, but when I tried to start the engine, again I found only the starter fluid works. This means at least there is a correct flow of gas to the carburetor from the gas tank after the initial repair. After installing everything back with the new carb and fuel line, I checked that gas is flowing out this time from the bottom of the carburetor. Since the fuel line to the carburetor got stuck I couldn't take off the fuel line from the carburetor, I bought new carburetor and fuel line to replace them both at the same time. I can start the engine with starter fluid. The fuel line is clogged somewhere by taking off theīottom bolt on the carburetor, no gasoline is flowing out. I first identified the problem in fuel flow.
