Putting new gas line on as I have had lots of trouble with gas leaks. anyway gasket fell off of carb. can you send a pic of how it goes on? the gasket that is

It sounds like maybe you tore the gasket that attaches the carb to the block. Check that, Also make sure your screws holding the carb. in place are tightened.

you havent said what engine you want the gaskets for!! the serial number is fo the machine only. Im guessing that it has a honda gcv135/160 so i have attached pics of the carb and gaskets and the order the go in. make sure you get number 15 the right way round or you will block up air transfer holes!!!

I own an Andretti M50 and I had 2 different gas leak problems, and neither was a stuck float.
- the gas filter that comes with the bike is a 2-piece screw together unit and the gasket between the 2 pieces leaks gas down onto the cylinder!
I replaced with a $3 one piece from Pep Boys.
- the second leak the gas just poured onto the ground. It was caused by poor design and tight tolerances where the fuel line attaches to the carb. The fuel line would get guillitoned every time you hit a bump by the engine swinging the carb tight against the frame. I rotated the carb in its manifold away from the frame. (you have to cut the nubs off the carb manifold to rotate it).

fuel line goes from gas tank to carb. and from carb. to primer bulb and back to tank.
make sure you put a new primer bulb on it.

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

Carb gasket will most likely need to be replaced. Good idea to pull apart, clean and soak carb and floats anyways in the process.

double check your carb as it should have a screw for the fuel mixture. some carbs have a plastic piece over them that only lets you move the screws so far if you need more extreme adjustment they pull out about a 1/8th of a inch then you can turn in then push it back in, same principals as making a flame on a bic lighter bigger, if you cant find it take some pics of your carb and email them to me @ [email protected] and i will point them out

Replace the fuel filter. Sounds like you have the primer lines hooked up backwards.
