Hey I bought this sled a couple weeks ago with a fresh motor.

Problem is if it is outside in the cold its impossible to start unless I either pour mixed fuel in the spark plugs (pain in ass) or give a spray of ether in airbox (possible pain in wallet). After its started it runs like a top and starts half pull. Also if its in a heated garage starts half pull as well first time (not my garage).

I've tried turning off the fuel to see if it was flooding no help, rebuilt fuel pump still no change.

Talked to a guy he said he had exactly the same probs never did find out what was wrong.

Any ideas?? I'm stumped =[

hmmm... Anything??

Choke cables out of adjustment?

If the fuel pump was rebuilt, I would look to the chokes being set too loose. Not enough fuel when the choke is on and it is cold.

Thanks, I'll give that a try today.

Copied from my response to another thread:
What I did on my '94 XLT was to screw the adjusters out on all three choke cables until there was about 1/4" of play in the choke lever when it is in the off position, and then back one of the cable adjusters off until you get about 1/8" of freeplay in the lever. Then back each of the other cables back in until you can feel each one start to reduce freeplay below 1/8" at the lever, then back the adjustment back out to 1/8". Snug the jam nut on each cable so the adjustment doesn't come loose.

Maybe the chokes are actually seized in the open position, I have heard of this happening before, I'd check to see if they are actually moving first.

If you can't figure it out just install a primer and use that rather than the choke.

Yep,,that primer idea is a winner fella's!!
Another really good possibilty is low float level.. THe lower the level the harder for the fuel to move thru those tiny orfices.. I use an exterior clear hose on mine so I can see exactly how much fuel in the bowl.. Run them 1/8 inch below bowl seal line... Low float settings can also cause er to lean down at high r - not good for any motor especially a fresh one!!!
