12/23/2023 0 Comments Starting fluid lawn mower![]() On the other side of the carb there are 2 or 3 small holes which the front gasket is cut to avoid blocking them off. Take the float bowl off and turn the petrol onĬheck that the float drops & you get a good flow which will sop when you lift the float but stop before the float touches the body.Ī genuine Honda carb should have a tap on the side No air in the float chamber = no fuel out His has to line up with a hole in the gasket so air can get sucked up the curved slot. The back of the carb has a hole in the flange which is the air vent to the float bowl 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.

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. ![]() ![]() I have a MTD honda lawn mower (Model # 12AV55DQ713) with GCV190 engine. ![]()
