STIHL Intellicarb Carburetors

[bwalker]

Old sled: 1994 enticer 2. Pulled plastic skis and paddle track off low miles RMK 700. Choke circuit on the tekei carb is so good, it'll start at 40 below, no primer kit needed.

Bout the only significant carb issue ive had was a polaris trail that sat in Valdez in salt air for years with 1/4 tank of fuel. Fom the tank to both carbs needed cleaning.

Polaris jetted the fan cooled 488 way richer than the liquid-cooled fuji 488 in my widetrak lx. Was a total fkn gas hog till I re-jetted it near how the liquid cooled engines came.

Miss that polaris trail and my widetrak lx with the fuji 488's such bullet proof motors:

I had never heard of an Enticer 2 until now. We had a XLV back in the early 80's and that sled was bullet proof as those Yamaha fans are stout mills. It had the same motor as the VK 540 work sled, of which I am sure your are familiar. Still made globally too, just not sold in the US.

Yep! Right now, it's -20 below and my utility sled is crisp as a mother fker, pulling sled loads of wood. Somewhere around the positive teens, she's a smidgen doggy till hot. I dont change a thing.

I've owned about a dozen different 2 stroke utility sleds from about 1995 until present day. Arctic Cat, Polaris, Ski Doo and Yamaha.

Rarely has jetting ever needed changing. Especially the ones with carb heat, like the yamaha I currently run.

Oftentimes, in april, ill adjust idle air/fuel ratio ratio, is about all.

Driven them off the show room floor and they will indeed run just fine even when it's bitter cold. That doesn't change the fact that they are pig rich when warm.

Yah weird sleds, but well built. Almost a "mini vk 540". Geared LOW. The enticer 2 has coated pistons. Some sort of proprietary yamaha ceramic coating. The case halve sealant and the crank seals last forever. Koyo bearing all over the darn place. The rubber parts too, like the fuel pump diaphragm and the carb boots never get brittle. Think I'm bout 4700 miles, all pulling wood, slabs or trail groomer.

It's caught on fire once. Knocked a hole in crank case, gear oil turned me into a fkn fireball when it hit the muffler at 45 mph.

My food cache fell down on it and crushed the engine. Split the sparkplugs and bits of spark plug had to be fished out the cylinders.
Still fkn runs. Like every "stable Indian", I have a parts sled!

The newest vk540's, they went a little too EPA lean on the carb jetting, right from the dealers. Sht, even guys down Valdez (sea level) were reporting fuel economy figures I've NEVER heard of pushing a 156"x20" widetrack.

Then in places like Aklavik, Dawson, Ft. Yukon, they were burning pistons on the clutch side in that hard below zero. No fault of the sleds, just too lean when pulling weight.

Had to run that frog skin over the cowling openings, keep that moisture off the belt. Or the engine-shroud air passages from getting plugged with powder during full throttle teleports. They set kinda low.

Then there's that funky tillotson on my 1976 Elan deluxe twin with custom pipe muffler:

Fuel filter, fuel pump and butterfly carb was all stacked vertically! Easiest fkn thing to work on. The high jet was finger adjustable while u were full throttle teleporting!. How fkn cool is that in 1976?!

After a complete restoration, was tuning a fresh tillotson on 20:1 mix. Out of nowhere, 2 massive German shepherds were chasing me down. Anybody who knows elans, if it was a single cylinder, I would've been mauled to death. Slug bugs.

The more aggressive german shepherd tore a chunk out of my parka lunging at my back. Was only topping 25 mph. Tuning high jet under pressure, reached down, went half turn lean, and fkn teleported 35-40 mph.

Try that with ah round slide mikuni....

All the old sleds had a tillotson or walbro on them with stacked fuel pump and exposed jets. Polaris was one of the first to bring mikuni on the market in 1970 or so. Cat was running Kawasaki till 75/76 then on to Suzuki Kawi was fast but they peeled the chrome on the 440 real easy if not run fat. The 340 was nearly indestructible compared to the 440 and the 399 was good also. Only stupid thing kawi had was a center seal on crank that was put on before pressing crank together to make the two sides charge individually. They would go and it would not run well but eventually they made a 2 pc replacement for them that could be installed without splitting the crank. All the snowmobile manufacturers that survived the late 70 early 80’s had Japanese engines for the most part. Polaris used Fuji, cat Kawasaki and Suzuki. Yamaha used their own only one that didn’t was ski doo. Polaris quit Fuji late 90’s early 2000’s and now Fuji has sold the robin 4 stroke engines and the two strokes were stopped they now concentrate on their Subaru cars. Yamaha bought the small 4 cycle stuff and started into the lawn care business. About the time Yamaha bought robin from Fuji they made a run of 700 grizzlies that had Fuji designed engines that were larger than the Yamaha one but only lasted couple years. Done with my useless knowledge novel, don’t want people comparing me to some others on here that can’t shut up.

The newer VK's have the 1 carb into two cylinders setup?

Yep, newer flat slide carb with heating element. Single carb. Completely different from the old ones. I'm trying to pick up 2(a 2021 and a 2022), for a remote commercial timber sale.

Nother weird issue: they upgraded to a 1.5" lug track. Most awesome, but the old tunnel design was unchanged. U can't run studs, not enough tunnel clearance. Some guys are getting into over flow or on glare ice and literally can't get anywhere without track studs

Studs long enough to deal with a 1.5 lug track are pretty tough on track durability. I have this problem with studded 1.25 tracks. All that leverage of the long stud eventually tears the rubber.

So a suggestion for next years OPE GTG is to add a snowmobile grass drag event,. And if there's a pond nearby maybe even some water skipping.

I totally agree.
