Thankfully no need for Beno or Gas X for me at this point. But in asking the family what one thing they would change on the Coach. Without hesitation the CFO said "the Exhaust smell".
As it stands currently, Its a 403 with 120K miles. Stock Carb, stock distributor, good Manifolds, Lenzi copper gaskets, New mufflers, collector donuts, no leaks.
The smell is not leaching into the coach per se. Its the eye burning and choking fumes when idling that is the offensive smell. So much that we have to close all the windows in the house, neighbors too, and it sticks to my clothes instantly.
What I do know. The carb needs to be rebuilt. No question it lopes when starting up, has hesitations and I know its time. None of the PO paperwork suggests that it was ever rebuilt. The distributor is in good shape, and working properly. Timing was set by a shop per the manual specs.
So my questions, Do you think a rebuilt carb (Patterson) would help clean up the eye burning smell? Understanding that there are no cats on this, and no real emissions to speak of. Would it at least help?
In reading up recently on the FiTech set up from Mr. Work, I read that system helped clean up the smell just a bit. So thats a possibility on the table.
I am by no means a carb guru and will gladly pay to have that properly redone the first time correctly. I know enough to not know if its an air/fuel setting out of whack, or something else. So if it is a fuel delivery issue, would you have the carb rebuilt or go to EFI?
What say the masses on how I can make the CFO happy?
77 Royale, Rear Dry Bath. 403, 3.55 Final Drive, Lenzi goodies, Patterson carb and dizzy.
