2 1994 SP in peices
#1
I am no stranger to technical work - boats, antique mopeds, cars of all vintages, old outboards. I was feeling brave and pulled home 2 94 SPs with the carbs removed and a box of parts. The story checks out - guy and friends went in on them, run them around, guys buddied let him do all the work and storage, and the guy said heck with it when no one helped him take out the carbs for rebuilds. He sold them to me super cheap, new carb kits included.

So I need some advice - I rebuilt the one carb last night and tested the popoff pressure, and all seems well. I put the jets back the way they were when I started the rebuild. The high speed jet was about 3/4 turn before I rebuilt it (the plastic cover bit was forced past it's stop. Now that I have rebuilt the carbs, should I turn that one in all the way for the factory "0" setting, or start from where it was?

Read the carb rebuild thread at the top of this section to get good insight into the carbs.

As long as you have the stock main jet then set the high speed screw to 0 and set the cap on so you have the 1/4 out ability. The references I have seen show the high speed screw as a "bypass" of the main jet that will only allow extra fuel into the motor. Something I wish the would have built into snowmachine carbs.... Turning the screw out will only richen the top end, all the way in it relies on the main jet only to meter fuel flow at WOT.

The carb kits were Genuine Mikuni correct?

Hmm. The carb kits are 'winderosa' but seem to have all the specific buts (red dot on diaphraphm, etc). Am I going to regret things shortly?

Oy, these carbs are a pain to get back in. Grey fuel lines are fairly stiff, but I don't see any green goo....why do I have the feeling I'll be changing them out anyway?

Well the Winderosa are junk and one of the worst. Get genuine Mikuni or do it twice and still end up getting Mikuni.

If the fuel lines are hard and especially gray replace them with standard black 1/4” automotive fuel hose.
