  • Hard starter!

    On-going saga of old King Quad.....
    harder 'n heck- no impossible- to start in the cold! Is this a common problem for the beast?
    Started fine in moderate temps. Battery is up and it turns over fine- just doesn't start. Had already put "Heet" in the tank, so don't think water in the gas is a problem. The choke (is it really en enrichener?) doesn't seem to rotate far back on the handlegrip... can it be adjusted? Would like to use this rig for ice-fishing, so would appreciate help.

    The saga continues............ )

    Once it does start, does it blow smoke for a bit like it was flooded? My 250 did that for a while and it ended up being the vacuum operated fuel flow petcock (a mere $80). The thing wasn't shutting all the way off when the engine turned off and it would flood the cylinder. When you crank the engine and generate some vacuum, it is supposed to open the petcock and let the fuel flow and completely shut the fuel off when there is no vacuum.

    The other culprit would be the choke. If it isn't fully rotating, you aren't getting full choke. You should be able to pull the air intake off the carb (or even pull the carb off for that matter) and actuate the choke while looking inside the barrel. I think the mechanism is visible, I may be wrong. If you are only getting 1/2 choke, then you know the cable is stuck or gummed up. If it goes full choke, then you have other problems.

    A couple of options here. I bought a cable lubricating tool which works so so. It clamps on to the end of any brake cable, choke cable, etc. and allows you to put the straw end of a spray lubricant into it and force lube down the sheath. It only really works if you keep up on a cable in good condition. If the cable is gummed up, it won't help much. The other option is to change the choke cable.

    Good luck!

      Yeah, Mud...

      ... "Once it does start, does it blow smoke for a bit like it was flooded? "...

      It does do that. Maybe if I just turn off the fuel petcock, huh? I have a Polaris snow machine that does that too if I don't turn off the petcock.

      I'm thinking that the choke cable spirals around a shiv inside a housing on the side of the carb...? If so, it looks pretty hard to get to w/o taking off the fender. I don't know if the choke cable is fully functioning. Maybe I'll try to take off the air intake to see if the choke is working.

      Thanks for thhe input.

        symptoms indicate choke sticking or malfunctioning. What color is the smoke, Sayak? If its black, its choke stuck on or partially on...

            Sound to me that you might need to clean out your pick up jet or you might have low compression and the temp really has something to do with it and gas up here in Alaska is totally different . Give me call (907)529-7633 I work on these thing all the time
