Just realised what i had in my yard - Page 4 - Snowmobile Forum: Your #1 Snowmobile Forum

I personally would get it to turn over freely before i started fixing the other stuff. Becuz why go through the work and money getting the wire fixed when it wont turn over or run? Then i would work on the other stuff.

TwinsofMLB · 08-02-2009, 09:29 PM

Oh and the right ski isn't turned as far as the left. That could need a kinspin or spindle. Do they both turn as they should when you turn the handle? Boy she's a dirty little thing isn't she? lol

I noticed it's a single carb and there's no airbox connected to it. Do the older models have no airbox or something? How do they filter the air???

YamahaSS440 · 08-02-2009, 09:49 PM

snowmobiles generally dont need an airfilter because theres not much stuff in the air to get in the carb. Really the only reason id have an airfilter/airbox on a sled is to keep the snow out.

It's definitely not the original carb. Looks like a kehin slide carb. And it looks like a 1973 lynx 440. It's got the green fan shroud which they used in 73, the 72's had red stripes on the shroud. If you don't put 2 cycle oil in the plug wells you can also try marvel mystery oil that stuff's pretty good too.

no the skis are fine its just when i lifted the front end using the lil metal piece that sticks out to move it back ma leg kinda moved it a lil when i set it back down and i was to tired to move it back, no i persume there was a air box on in befor emy uncle from i herd from m father today got it to run liek 3 winters ago but didnt idle just started and died also sat for a long time prior to this so yea carb prob dirty. Also about how to get the clutch moving agian what do you guys sugest like poor a lil move it back and forth until it will do a full roation

YamahaSS440 · 08-02-2009, 10:09 PM

maybe put some oil and let it sit in the cylinders over night

catfan · 08-02-2009, 10:13 PM

yeah try and put oil in it and let it sit overnight or longer and cross ur fingers it comes outta it.

deozpester91 · 08-02-2009, 10:19 PM

i can dumb alot in there and let it sit for 2 weeks dnt bother me lol ill pore it in go back home coem pack there in 2 weeks to cut the grass and do a few quad races lol how much am i looking to poor in this is the first time im working on a motor that inst turning so freely or mostly at all lol

other serious note what to do with the gas tank

YamahaSS440 · 08-02-2009, 10:35 PM

see if you can remove the tank and swish new gas in there to get the old stuff out. thats what ive done

deozpester91 · 08-02-2009, 10:51 PM

Removing the tank easy or so i need to finish my college summer classes so i can take a week of and just play with this thing

YamahaSS440 · 08-02-2009, 11:09 PM

Ive seen numerous arctic cat gas tanks taken off and they usually are pretty easy

catfan · 08-02-2009, 11:17 PM

if the tank is rusted u can take pea rocks and put them in the tank and shake it around for prob an hour it should get rid of the rust, then dump the rocks out and rinse the tank out to make sure there all gone. ummm idk i usually put about 1/4 the quart in each cylinder u cant over do oil.

deozpester91 · 08-02-2009, 11:38 PM

i read that wrong thought you sais pee rocks i was gunna start peeing on rocks and throwing them in there lol so many problems so little time

TwinsofMLB · 08-02-2009, 11:51 PM

Lol I'd like to see someone get the tank out of my mach 1. In my case syphoning the gas out is the only way because it's the front of the seat and there's a LOT of stuff that would need to be removed to even be able to reach in to look at it. Btw, I don't think that the clutch situation is that abnormal... mine won't move by hand. The drive pully does but not the clutch. Mine starts and runs good though.

deozpester91 · 08-02-2009, 11:54 PM

You just made me think of how hard this is really going to be for the gas tank lol :'( its empty inside other then maybe less then a cm of fluid on spots its the rust that i wanan remove argh this *** **** sled all theses problem with 1200 miles lolol

TwinsofMLB · 08-03-2009, 12:17 AM

Not unless the tank is buried in the seat lol. No your model isn't as difficult, the 1991 mach 1s were built to be IMMENSLY difficult to work on lol. Probably to get more money for the mechanics I'm guessing. You should see the difference of how everything under the hood compares to yours. You would know why I call it "the beast" lol.

YamahaSS440 · 08-03-2009, 12:18 AM

well, if a sled sits outside, thats what happens.

You're probably right about the model year, but the carb is a WahlBro Pumper.

deozpester91 · 08-03-2009, 02:01 PM

So pretty much the same with the cleaning of the carb that the site shows rite? when i give the cylinders oil and let it sit for 24 or more hours lets says do i want to move the clutch sly back and forth or just try to do a full rotation

TwinsofMLB · 08-03-2009, 03:39 PM

Idk if you know this, but my grandfather stressed it on me so much that I think you should hear it too lol: never lubricate the clutch or you will have PROBLEMS. (This doesn't really apply to what you're doing now, it's just in case you think of doing it on your own.)
