Bluebird428, I am still tinkering to get it nailed down as I haven't had it out in a couple weeks, though it runs WAAAYYY better than it has for the last year. There is only a hint of the gassy smell so I just ordered the 1453 metering rod and 1427 secondary you suggested and they should be in tomorrow around noon. I thought I would give them a try as I want it to be right, not almost right! You have been a great help and I really appreciate it! Sad you went through the issue with the Q-850 but at least you knew the solution was within reach. I am sure you have a reason for trying to go that route but I would stick with what works.
