My snowmobile kart project

[Dang]

ok i figure it out like Ed said it is a fuel return. The fuel tank have 2 hole for 2 line connectin to the carb, the gas line connect to top carb piece and bottom gas line connect to bottom carb piece. I dont see why its made like that but sure confused the crap out of me. The engine i believe is a ski doo 340.

 

[Dang]

the engine has a high speed and low speed needle so anyone know the default setting for it?

 

[kibble]

Proper connections are indicated in pic.
Carb not identical to yours but is basically the same.
I use these almost exclusively on all my 2 cycles.
May have torn diaphragm/stuck needle.
Get the kit and meticulously clean guts before re-assembly.
Get a better camera. Very hard to tell what you have.

Russ, are you sure your pic is labeled correctly?

 

[Russ2251]

Varies, start with 1¼ turns out each to be safe.

 

[Kenny_McCormic]

I like to start with 1.5 or 2 turns out and lean it out just till it quits 4 stroking.

Russ, are you sure your pic is labeled correctly?

Swear by the hair on my chinny chin chin. All my HL's the same. Microscreen under plastic nipple for filtering.
I can post other pics if needed.

 

[kibble]

Holy crap, I thought it was the other way around! No, I believe you, I did see the little screen behind the plastic part.

 

[Dang]

i though H needle are lean out more then L needle so jus lean both the same?

 

[Russ2251]

Need screen for fuel. Pulse is just moving air to operate pump and needs no filtering of any kind.
Someday you guyz...nevermind.

Varies, varies, varies. I stand by my post. And never run a 2 cycle lean. Can even screw up a 4 cycle if left uncorrected long enough. Worse than running without back pressure.

They're not necessarily the same, you may have to play with each one until you get the response you want.

Someday you guyz...nevermind.

Hey, I didn't say anything about "I read somewhere"...

 

[Russ2251]

Sorry kids...got a short fuse today. Supposed to be vacation day for me but got dragged into work anyway. ...so here I sit...

 

[Dang]

jus when i tune the needle got it running the pulley cord broke had to take the whole crap out and spend like over 2 hours jus fixin the cord and i still cant get the darn thing to retract the cord back.....

Out is generally rich,just be very careful not to run lean and have a meltdown.

 

[Dang]

so my pull start rope snap and i took it apart and the pieces jus pop out. I was able to turn and make the rope retract again but after i had put all the top pieces together it wont retract maybe i am not putin the pieces order correct so help please. This is the order i had it on the paper. There is like 2 pieces that have teeth around it i took a closer pic to spot it.

 

[Dang]

these rope pulley system are so complicated to put together its frustrating......

 

[Kenny_McCormic]

Thats why electric start is so cool.

 

[2or3wheels]

dude get the manual for the engine, i would be lost if i didnt have one for my 3 wheeler motor(like a forigen country in the pull starter)

...of course you know, Dang... I'm watching this post like a hawk to see how it pans out. I'm also trying to strap myself to a Snow-Mo motor, but your set up is NICE! I've been trying to figure out your motor too, from the pix. Not a Rotax, maybe a Cuyuna or a Chaparral, like Ironman's?
