  1. Boy, this is a tough one! Reminds me of a snowmobile I worked on once. The small wire that fed the external ignition coil was breaking up inside, while the insulation looked perfect. Intermittent issues are the worst!! Hope you get it figured soon.
  2. I'm a fan of the Japanese made quads, especially Honda and Yamaha. The others, not so much. Stay away from any mods, even with the good ones! stock is best....
  3. All I can add to this story is it's an Arctic Scrap....not a fan!
  4. Moving the choke lever in the direction of the arrow is "enrichening" the mix, moving it forward/away from you is the normal, run position.
  5. Good eye Frank! It looks like it's twisted alright....screwing the main jet back in will hopefully get in back in alignment.
  6. Sounds like you've done your best to get it out but if it's that stuck you'd better leave it be. Normally they're not that bad to pull, that's why I wouldn't be surprised if there's corrosion involved. I've worked on many King Quads over the years and this part often needs replacing. Once the needle wears into it enough, they will run rich and make the sparkplug get black. You will know if that's the case pretty quick.
  7. I would recommend removing it to clean/inspect/replace if worn. They usually pop out with very little effort.
  8. The needle jet is removed toward the slide, just like it's shown in the parts diagram. When you say "downward from float" I assume you mean with the carb turned upside down.
  9. It goes up to the top, the main jet screws into it from below which keeps it in place.
  10. https://www.ronniesmailorder.com/oemparts/a/suz/50d0a5aff870022c2c534c07/carburetor-model-x If you refer to the parts diagram, the piece you're trying to remove is #6 - the needle jet. These often wear out and the inside diameter increases causing a rich condition. Carb kits don't include this part but it may be required to get the carb working properly.
  11. The tube that's threaded for the main jet can be removed, it needs to be pushed upward and may require a small punch to loosen it. There are small holes in it that I believe davefrombc referred to. I didn't see any pictures of the needle & seat (aka float valve) that is retained by the phillips screw - did you replace the o-ring on it already? The plastic piece in #6 & #7 is necessary for the spring to rest on - it looks like you've got it on correctly.
  12. Something to bear in mind: if the adjustment screw is on the engine side of the carb (like this one) it is a fuel screw, so turning it out richens the mixture. Most 4 stroke carbs are this way. If it's on the airbox side, it is an air screw - common on 2 strokes. This works opposite but really does the same thing. It just fine tunes the pilot (slow jet) circuit in all cases.
  13. Start with the simple stuff: pull apart any connectors you find, check for corrosion, spray WD40 in them, remove plug cap & cut back the wire a bit for starters.
