ok, got the manual open.
It's a 496.7cc Rotax motor with Mikuni VM36-83 carb. It doesn't have CDI ignition but it has points or "ET".
If you suspect the points bad, I do have a bolt-grip puller to remove flywheel.
Just looking through my manuals.
Maybe throw tarps on these things and play online pc games for the winter. hehehe
I can call you if you want and answer and ask more questions if you want.
later........

thanks Vic! i will check that switch. also will take more pics. what would the function of a tether switch be? i have a short, thick piece of rope wrapped around a bolt laying by my chaincase cover that i have no idea what it goes to?
as to your issue, is the compression good? make sure spark plugs are gapped correctly (i couldnt believe mine were .016--never heard of one that small). i'll
get the trailer ready...i worked with a guy from Milwaukee who went on and on about how good the food is there

So you got snow and drove it around? I am confusing myself because I am looking at 2 different posts and having beers. Recoil works good?
sorry, probably should get off computer.........

If you hook a rope to both ski loops you should be able to pull it across the yard with a tractor or atv. I do it all the time with my sleds. Clean the points if you havent all ready a lot of times with sleds that have been sitting the points get rusty. Points should be gapped to .014-.017. I would give them a quick file with a points file and clean them with a new dollar bill or slip of clean paper. Don.t use sand paper on points it leaves a residue on them. Disconnect harness at engine. Are the plugs good/new? How about the plug wires?

txmnjim

i was wondering if this could damage/break the track or any mechanisms?
i will check the points. plugs are new and plugwires seem fine. i have a buddy
thats knows much more about these things than i going down w/ me next week, so maybe he can figure it out? now, if this weather will stay good...

If you are pulling it over smooth ground it should be fine. Might be good to lift the back end and roll the track over just to make sure it is free. You should be able to turn the secondary clutch by hand after you take the belt off.

Viktory2k1

so your not going to call or come over with it? PM me your number.

txmnjim

thanks for the ino SB49! i will try it next weekend.

Hey there,
I'm new to the forum, I was actually searching for anyone else with one of these sleds as I just finished restoring mine!

I have a parts sled available that some pieces may come in handy for ya.

More to the point, I fought a no-spark issue for quite a while on the PTO side of the engine. After replacing condensers, and checking timing over and over again, I finally found that the PO had replaced the points and put one of the ring lugs on the points bolt the wrong way allowing the lug to contact ground, not allowing the condenser to charge... Once it was "bent" away from grounding out, she purrs like a kitten & starts on the first pull every time! (or from just a "bump" of the starter).

Kill switches on these certainly throw a wrench into the mix! While I was trying to diagnose the issues with the engine, I tested everything with NO connection to the chassis. This removes the possibility of a kill swx causing issues (just make sure your green, Yellow, and black wires from the stater plate are wrapped with electrical tape to prevent shorting!

I have had this sled sitting in the back of my barn for the last three years after refreshing the engine. When I tried to get it going back then, I threw up my arms. After testing the coils over and over, I finally ordered new condensers. When I got around to pulling the stator plate to replace them, I saw the ring lug touching the mount. Once I bent it out of the way... voila, full fire! It kills me since I work on point-ignition systems all the time, just one of those "duh" moments I guess..

I have completely rebuilt the harness in my sled now and have put on a larger carb. I think I could probably build one of these things in my sleep now! The only draw back is, living in Indiana, we might get 1-2 good weeks of riding weather But, thinking back to the mid '70s around here... Anything is possible!!

Let me know if I can be of help!

-Nick

thanks for the info Nick! i will definitely check those points. problem is i'm fast approaching the limits of my mechanical knowhow will also definitely check those wires that went to the starter...i think its just kind of flopping around now.
