My King Quad was running fine and then decided it wouldnt crank again. I can spray fuel into the carb and it will crank and cut off. I removed the fuel line and could blow thru the line into the tank but couldnt pull any from the tank, also I removed the top of the carb and pulled what looks to be the diaphragm out and sprayed cleaner into the carb, placed it back and again it fired for a couple of seconds and cut off, it would only idle, couldnt throttle it none. everytime i messed with this it would idle for couple of seconds and shut off. other than that it will not crank at all.

Im guessing maybe the diaphragm or something but I dont know, any ideas??

thanks in advance

Fuel does not come out at all of the fuel line, i can however blow thru the line. Nothing was done except changed the air filter. The engine turns over fine, nothing electrical seems wrong with it. Its like its not getting any fuel to crank or run unless you manually give it some!

Could be your fuel pump. It should pulse when you take it off and crank it. Check the vacuum hose to it for holes. Also check if there is fuel in that vacuum hose. If there is, your diaphragm in the pump is shot. Also be sure there is enough fuel in the tank to be above both inlet screens

You can check the fuel pump by disconnecting the fuel line at the carb and hitting the starter. Gas should squirt out of the line in small pulses. You can check the vacuum line at the front right side of the carb by removing it and looking to see if it is wet. Since it is a vacuum line it should be dry as a bone. Also look at both lines for cracks. If you have to replace the fuel pump, it is on the left side of the frame below the handlebars. You will have to remove the front rack and fenders to get at it. You might also want to ask oxidized_black for a service manual download. It has a couple pictures of the fuel pump. They aren't real good as far as showing the location, though.

And as oxy says check the petcock. If you pull the line off at the petcock, gas should run out of the petcock when you turn it to on or res. The gas then goes forward to the fuel pump. then down to the carb.

      How did you get into Quads?
      By Mikey69
      Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

      TRX350D fuel pump problem
      By semicolon
      Hi, I am having issues with my TRX350D fuel pump.  It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals.  I have fitted a new pump, fuel cut-off relay and rectifier.  Still nothing!!  The pump runs when attached to a battery.  The engine will start on the choke and the filter fills with fuel but it will  not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine.  Any ideas where to go from here would be very much appreciated!!

      2005 Bruin 350cc Oil pumping into airbox
      By BruceG
      Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

      Help with 1987 Yamaha Big Bear YFM350FWT Carb
      By ResQ91
      Hi Guys!

      New member and could really use your advice. I would have to believe this has been an issue for others but a search here came up with nothing......? (Probably me not doing search correctly)
       
      I have an 87 Big Bear 350 YFM350FWT
      The OEM Mikuni BTM carb is shot and would rather replace than rebuild.
      It is no longer made and I have had good luck with NICHE carbs so I ordered a #K-CRB-0006 This was what they said was replacement when ordered. This Carb only uses 1 Throttle cable. The Slide is linked so it uses one. (OEM had 2nd cable coming through top to move slide)
       
      Problem is when I ordered a replacement Cable from NICHE (#C-CBL-0061) the Cable wire is a little short, not allowing Throttle to return all the way down to Idle position. I called NICHE and they are at a loss. Haven't gotten back to me after 2+ weeks.
       
      What would you recommend other than a carb rebuild?
      Can I just use 1 of the OEM cables (It is the right length) and snip/disconnect the other that went to top of Carb for Slide?
      Or ??
       
      Thanks in advance for any advice you have!!
       
      Dave
