I have a 52 CA that I recently repainted. I installed a new stanley muffler with a rain flapper. I am getting a lot of soot on the hood. Before I painted the tractor it had a straight pipe with a turn out away from the tractor. I never recall getting soot on the hood, but the tractor looked so rough I may not have noticed. I like the way it sounds now, but I need to get rid of the soot. Does anyone have any insight? Thanks Lynn

Put a turn out on the muffler would be the only solution. ------------- When someone tells you Nothings Impossible, Tell them to slam a revolving door |

May also wait until the "new" wears off the muffler?

I had the same problem after I painted my WD45. Sometimes starting, I'd get a little blown out and deflect down on the hood. I went to NAPA and bought a 90 degree exhaust pipe and cut it to blow off to the side. no more soot. http://s1359.photobucket.com/user/dmckinney45/media/100_1085_zps846ece23.jpg.html" rel="nofollow">

Lean the mixture out a bit and run some Seafoam thru it. If there is soot coming out, there is soot inside for whatever reason.

| If you don't run it very long, it might be condensation, carrying the soot out. Always run long enough to get to operating temp. Might also want a turn out on it, for running cold... |

I have the marvel carb with only idle mixture adjustment. I will double check the adjustment. Has anyone ever found the need to run a smaller main jet on a stock engine? |

| One thing i have never touched is the timing. Its always started and ran good so i never fooled with it. I replaced the points condensor cap rotor plugs coil and wires just never adjusted the timing |

| Nice lookin 45 there Dave, big rears and especially those big multi-ribs on the front really set her off. |

Condensation. On a cool day with plenty of humidity it's going to happen for a minute or so until the muffler warms. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian." Henry Ford |
