1993 Arctic Cat 440 L/C -- New Owner Help?
I just recently purchased my first snowmobile, so am extremely inexperienced with these pieces of equipment. I've worked with engines, but never a snowmobile.
I'd like to have this up and running by snow seasom, but need to get some work done. The ignition has the key broke off in it, so need to order a new ignition for it (had to use a jumper wire with the harness from the handlebars disconnected). It hasn't been used in awhile, so I am starting by removing the fuel tank to remove the old fuel. I also need to remove the 50:1 injection oil and pick up more. What other fluids should be changed? I also am planning to rebuild and clean the carbs -- what carbs are on this? Also, fuel lines... 1/4 ID?
I was able to start it, but ran very smokey, sort of rough and would die when given throttle (thinking because of old gas).
Other than dumping tank, oil, changing fuel lines and dealing with the carbs, what other things should be done? I'm hoping these issues are what were causing it to run the way it did.
Already having fun removing the seat to access the fuel tank... 1 of the 2 screws in the rear is stripped so now need to find a way to get it out of the cramped space.
Thanks in advance and I am looking forward to learning as much as I can.
