Muffler gasket install direction - fixing a loud cart
Does it matter which side of the muffler gasket faces the engine and which side faces the muffler (I know...probably a STUPID question)?
It seems that the gasket has something different about each side. Does the "side with the flat ring" go to one side or the other..or does it not matter? Also, can you over-tighten the gasket? My cart seems very loud and the old gasket was really hard and black so I figured it was a cheap replacement and we can see if it fixes anything. Other ideas to check when the cart seems loud? |

Re: Muffler gasket install direction - fixing a loud cart
Two strokes are inherently more noisy than four strokes as on the power stroke the piston passes the exhaust port whilst there is still an active explosion. This will result in the exhaust gasket being subject to much more thermal stress.
Picture 1 should go against the pipe and picture 2 against the cylinder. 1 has a bigger mating suface as it has to crush up against the rolled flange of the pipe whereas the mating surface of the cylinder should be flat. It is possible to over torque the nuts on the union and if you break the stud (especially if it shears flush with the cylinder) you will be in a world of misery. Just snug them up and give a little extra push. Dave |

Re: Muffler gasket install direction - fixing a loud cart
Dave,
Thanks for the reply. I will install the new gasket and see if it helps any. Just as a point of clarification, you talk about 2 strokes...but my engine is a 350 robin which is a 4 cycle. Were you just adding that for clarification of anyone reading the forum or am I missing an important point in there somewhere. Ed |

It appears that I am missing an important point ! For some reason I read that you had a 2 stroke. Sorry, need more coffee.
