• I am getting worn out moving your "For sale" threads, including loosely veiled sales pitches for "How much is it worth) or Wanted to buy to the swapmeet.

    I will no longer be moving them for you as I have been in the past.

    Some days are 20 per day.

    If I see it, it will get deleted.

    I try to help you...please try to help me.

    Thanks.
  • I've received emails and PM's asking me about "Group Buys" and promotions.

    A Group Buy here on SnoWestOnline.com would be a situation where a normal member (non vendor or mfg) personally collects orders from other members. That member then uses those orders to negotiate a better price with the Vendor/Mfg for HIS/HER "Group" of buyers.

    Here is an example of a viable "Group Buy"

    http://www.snowestonline.com/forum/showthread.php?t=269222

    A promotion that has the words "Group Buy" in the title is still a promotion, and from the rules that were handed down to me by Harris Publications is that non-advertisers cannot run promotions or open sales programs on the forums outside of the swapmeet.

    If a members wants to become a group buy manager, maintain a thread and collect the funds and negotiate a group buy... as a member, you are welcome to do that as long as you are not attached to the business of the vendor or Mfg.

    If you are a vendor/MFG and you want to offer an EXCLUSIVE "SnoWestOnline ONLY" promotion that is exclusive to snowest readers, please contact me and you'll be able to put it up in the Polaris forums.

    Also, before any vendors/mfgs get all "riled up" over this know that the moderators are strictly volunteers and do not receive a dime from any advertising $$ spent on this site.

    As ALWAYS, since DAY ONE of me becoming a moderator, I have pioneered, supported and encouraged vendors and mfgs in getting the word out to our readers with "New Product Announcements.

    Have a great season.

    From this point on, all vendors/mfg's promoting Pre-Season tiered sales programs, in the Polaris Forums, that are not paid advertisers will be appropriately moved to the swapmeet section of the forums.

Mikuni TM40 Carb Rebuild Question

I am accustomed to purchasing rebuild kits before tearing carbs down. I am having trouble finding a kit for this carb. Do these carbs rarely need rebuilding or what? Is this an uncommon Carb? Should I Upgrade?

Mikuni flat slide rack carbs?

They are very common and a very good carb. Alls u really need to do is pop the bowl off. Make sure u use a good correct size Phillips head on the lone screw, and spin the drain plug off. Take the main, pilot (careful of springs and washers) and starter jet off. Choke plunger out, fuel screw and crab cleaner through everything.

The bowl gasket is o-ring like and easily re-usable. The plastic float assembly isn’t really adjustable, just make sure needle holds pressure.

That’s it. Shouldn't need to go further

Yeah, unfortunately, they don't have a carb kit like you'd find with a common automotive carb. Not sure why since it'd be nice to be able to refresh all the rubber pieces. You can get the pieces through Polaris, but they're expensive.

The TM40 was fairly common on snowmobiles, Polaris used them on the 700s and 800s, several other makes used them too. It's hit or miss whether they need new pieces or not; given the prices, I'd say the best approach is the tear the carb down and see what things look like. If the rubber pieces are intact and not completely hardened up, you should be good to reuse them. A regular cleaning should be all that's necessary (especially if you avoid ethanol) until the pieces start showing signs of distress.

There aren't any upgrades, practically speaking; changing carbs around on 2-strokes, while possible, isn't as straightforward as an old small block.
