Smelly exhaust

My 52’ Hornet twin H has very smelly exhaust. Can’t drive into garage without stinking whole place up. I’m getting poor gas mileage too. What size jets should be used?  Maybe has wrong jets. Exhaust pipe is very black inside.

    I would guess your choke is not opening.

    Could be too high a float level, causing over-rich mixture


  • When did this start happening?

    Maybe a family of mice crawled up the tailpipe last fall, made a home in the muffler, and was ultimately cooked to death....
  • Put latex gloves over tailpipe every year, I do !
