getting ready for the season to come. For the last 2 seasons I have been trying to figure out why the sled is getting so cold blooded. It used to be 2-3 pulls done when it gets cold. Now I could pull all day and nothin unless I use some good ole either.

I have had the carb rebiult and the fule filter replaced. all the fule lines look good. What else could be wrong?

Thanks in advance for the help!

Could be a small crack or hole worn through the impulse line from the crankcase to the fuel pump causing the fuel pump to work incorrectly making it hard to start.

Thank you for your input, I am wondering if this Impulse line is a fuel or a vacuum line? I was thinking of replacing all the fuel lines and cleaning connectors thinking air may be getting in the lines. But once the sled is started all is good. I would think if there is a fuel or vacuum issue I would get backfires and irregular throttle?

The impulse line is the hose that goes from the crankcase (usually on back,carb side) to the fuel pump. If the impulse line is cracked or has a small hole in it, the sled will be extremly difficult to start. It may still run after you get it started but if it's cracked the fuel pump won't operate properly making it hard to start.

When is the last time u had the carbs cleaned, usually the pilot jets will become plugged or the choke circut will be restricted with old gas varnish , this is a common problem with todays poor gas, cleaned hundreds of carbs over the past 23 years as a sled mechanic, also check your compression, should be 130-150 if in good shape.

    • Now that the corn is out and the ground is white the birds are really showing themselves. Three times in the last month I have seen 50-60  birds on a short day. Nearly every one was in a group and they are concentrating in dense thickets of plum brush.    And there are literally next to no hunters out and about going after them which is a big change from even a decade ago
    • I too remember these stupid punch cards in High school.  All the Nerds in the Computer class did stuff with um! 😅
    • I remember those stupid punch cards.  I was in junior high and had to “program” em in class.  I hated em and thought I’d just avoid using computers altogether! 😀
    • Good hunt in SD today: 
    • Had the day off so hit some public land around the Mitchell area today.   Did well, my favorite upland gun is my O/U and is currently broke. Busted a firing pin and waiting for gunsmith to get a knew one made on a lathe. So today I brought out the old 870 which I haven’t shot in at least 5 years or more.   Thought it would throw off my shooting but to my surprise managed a quick double on 2 shots lol. it’s always amazing how fast a day in the field can turn around. And I really enjoyed shooting this gun again. It’s amazing how something so cheap and simple is so good.   Day started out really slow I couldn’t find birds anywhere and then found the motherload. Shot my 3rd bird, put it in my vest and bumped birds all the way back to the truck.   Good late season hunt just wish we had more snow. And this warm weather isn’t helping ice that’s for sure.  
    • Looks good!  👍 Lets see no work gloves, may be a hat?  Do you have a coaster under that hot pan mister? 😊
    • Steak fajitas tonight.
    • The window on AIX that I read Usenet News on was....   I started on computers with punch cards, then moved up to a 2260 and MTMT (multiple terminal monitor task) which was an IBM Rochester homegrown thing for running terminals attached to the 360/65 we had at the time.   Actual first computer I ever used was a CDC 1604 at the U of MN.....
    • There I might have made it a little easier to read😁    Hope we are all still around in another 10 years!!
