phatline

I forgot to check back for replies. Thanks folks! I just ordered a Mark 82 and will try that out. I haven't seen fouling of the plug but we also haven't had much snow. I've barely got 20 hours on the machine in the last few years. It's a real shame that our dealer here has no clue about this part. It probably means all of the thousands of Honda snowblowers running in our area (6200' and up, Lake Tahoe) are burning rich. Given the service life of a Honda I expect all of their emissions controls are long gone!

We just bought an HS928TA from our dealer in California. Dealer and our house located at 6400 feet.
I asked them if I need a high altitude jet (as per Honda manual, page 69) and, depending on the individual asked, they responded with:

* "No" (no reasoning)
* "Honda ships it with the jet it needs" (sounds reasonable... but somehow I doubt this)
* and my favorite: "That's silly--it only snows at high elevations."

I prodded and they said they can order main jet Mark 80, 82, or 85. But they have no idea which one would be appropriate for our altitude. I couldn't get through to anyone at Honda.

Does anyone here know (a) if Honda really does ship units with the proper jet for the dealer elevation, and if not, (b) how to pick the right size? I think I can install it myself but I don't know which jet to get :(.
