That’s great you and your Pops worked together. Create all the good memories you can and take none of the time you spend together for granted. I lost my Pop two years ago and really had no idea how much I was going to miss him. I’d give almost anything to have him back for even a few hours.
Love the sound of twin pipes!!!!! Classic!! So cool you working with your dad. I do the same with mine. We still ride as much as we can. Good times, keep it up!!
Pretty sweet that you kept your first mod sled after all these years 👍 My money is on the reeds, it shouldn't blow back through the the carb like that , I'd say check the case reeds and clean the carbs , if it problem still persists , check the crank seals , you can spray brake kleen at the clutch side seal to check same with starter side if you remove the recoil . Look forward to more in this series👍
Yea man bring the old mods back! I was just talking with old Bruno from the sled shop here in Edmonton just the other day, and he was showing me a couple of custom chassis Polaris wedge mod sleds he was building for a guy from the ground up. So cool to see interest in the old mod sleds coming back.
Oh man now you're going to need to get your tough boy bearing kit for the crankshaft, some special high-altitude heads! Don't forget the Boost bottle. LOL that has to be 3 to 5 horsepower with the Boost bottle After riding the new sleds the old ones getting stuff done is that much more amazing! I poured it out and 800xp origin to go into a gen 2 Mountain sled. I will tell you what that thing went! That engine have so much bottom end and flat power curve with the low gearing. Such a drivable engine. Granted back then on stock pipes we only had 175 horsepower with a power curve from engagement to wide-open there was no peek. Unlike today's engines where they get that monster has 165 horse
The PTO cylinder didn't seem happy but it's hard to tell over video. If you brought it to me I would just go through the carbs but the rack slides very rarely had issues but I would still put the 6 pounds of air pressure to the inlet and make sure that with the carburetors upside down make sure that they could shut off that 6 lb. Maybe a choke plunger is hung up? With a full tank of gas I would pull the pulse line and see if anything drips out of that overnight
Needle and seats in the carb not sealing correctly or stuck, possible even float that isn't controlling in the bowl. Plugged pilot jets/pilot circuit if it won't idle on its own without throttle. Pull carbs, full disassemble, ultrasonic clean everything. Once back together, check crank seals.
@@turcotte16 I think those carbs had a TPS system too. But im just working off the way back memory machine. The mods on that thing may have eliminated it
on that era of carbs they had a plastic needle and seat assembly. the assembly has an o ring that fits in the fuel inlet of the carb in the bowl. when they sit for a while the o ring goes bad. usual symptom is the sled gets the case flooded. replace the o ring and good to go. polaris PN 3131231 for thew whole plastic assembly. you can look up in the polaris parts browser by the part number and see where its used. but replace that o ring maybe. prob got it figured out by now though.
First step always clean a carb first on a sled tht is sitting it take 5-10 mins to drop the tank and pull the carbs out and then it’s two screws and 2 drains and two jets each
You eliminated that the impulse hose was allowing fuel to go into the crankcase, and I think float sticking as an issue also. I would still pull carbs, pressure test needle and seats. Check reeds for the petals being warped or the rubber delaminating if they are v force. Also confirm the chokes aren’t sticking on.
It's figured out now but I'm sure it was the idle circuits being clogged I'd change the reeds and check the intake boots as they have probably dried out and if they Crack it goes lean runs better than ever right until it pops ripping old school SWEET
My Dad still has a 72 skidoo that was bought new and my first snowmobile I ever rode. My brother still has a 99 polaris xc 600 that I broke my arm on ditch banging 2 decades ago
Wait. Why bother firing it up now, you don't even have the Turbo on yet? I bet you have one of those adjustable compression squish head gasket kits lying around somewhere.😉
If only you could rewind time and have old Larry rugland and the Pro 5 team build you a watercraft engine. Or since you're out in the mountains maybe a unionbay
