New X-Tream Clean Product Dealers

Have a carb off an '07 Big Bear 400 that sat a couple of years, probably more.  Friend asked me to clean it, which I did, soaking the jets and spraying out all of the ports with carb cleaner as best I could.  Replaced o-rings, needle valve & seat, tweeked float level.  Bike starts and idles well but doesn't want to pick up above 1/4 throttle.  That would appear to be in the slide needle range.  Main jet is clean, needle is clean and straight, diaphragm good.  It seems I saw (in a diagram) a port that comes into the slide needle area from the side.  This would be in the carb body between the main jet and the throat of the carb.  I would like to soak the carb in Gunk Carb Cleaner, the gallon paint can with a little basket.  Curious what Mikuni uses for bearings and seals in the throttle shaft.  I'm guessing HDPE or Delrin, or maybe brass; not sure what effect Gunk would have on the polymers.  Has anyone actually soaked a carb in Gunk??  First hand knowledge, please, and what effect, if any, on the carb.  Pulling the throttle shaft out would be a last resort.  Getting the butterfly screws out and staked back in would seem to be a nightmare.
Thanks
Jim

Also in which parts should I use it?  

Okay, so I have a 2002 Rubicon 500…bought it last year and it sat for several months until I put a new rear axle in, FINALLY got that done and was super excited to finally have my wheeler going, just to notice a strong gas odor. Popped the seat off and sure enough, pouring gas from the carb overflow. Fast forward a few more weeks and get the new carb and get it in, no leak! Yay. Except now I have no spark. 😒 I’ve tried another plug and checked and am getting no power to the coil pack. I’ve read and read and mostly what I’ve found is ECU, which is fine…but I like to exhaust all avenues before buying the more expensive parts just because I don’t wanna spend the money and it have ended up being something simple that I overlooked because I was trying to rush. 😂 I don’t know if it’s relevant, but I read on another post that someone had similar issues with theirs and it was the sensor on the side of the carb, just a thought since this literally happened after I put the new carb on. It also displays “- -“ on the display screen where it should show the gear position.

so I bought this raptor from my bubby because it sat in his garage for a year or suck long story short the guy who lost worked on it didn't know what he was doing can just did some of the worst work I've ever laid my eyes on but I recently had the thing running and delt with a lot of problems getting the damn thing to spark need new stator/ cdi and wiring harness and I had finally got the thing to run and drive had a blast omg I love this thing but sometimes I pray it would just stop giving me problems I've road the quad 2-3 time and found there was a huge leak and I took the head off its new btw its black and shiny but the last guy who worked on it did a horrible job and lost parts any ways I fix his mistake and bought oem parts and gaskets but when I when to put the piston back in I could not find a good thread on the orientation on all the rings on the piston and it is a bit confusing how people describe each ring I need a layman's terms like talk to me like I'm slow lol but don't be rude and I need help 1 in the orientation on all the rings and also my engine stopped sucking threw the carb can it be the valve is not seated on intake/exhaust should I reopen the head and redo the rings on the piston or can it be the valve spring gap idk I need help all I know right know is I need a break from the bike and collect information for now can I get some help without people pointing me in all kinds of direction 

was thinking most of us on this forum would have another ride, so to get the ball rolling...........
MY MAX 4 6X6 2009, now this will actually go anywhere including across the water. In the 3rd photo I had gone up the river about 30 meters then climbed up the bank, 6X6 owners call it "swimming"
