Hi all,

Picked this bike up about a month ago, and started doing some work on it. I ordered a carb kit from China, but got tired of waiting for it so I went to the bike shop today and picked up a Shindy rebuild kit. Took the carb out of soak, it has been in there for a month, blew all the ports out, cleaned what I could with a guitar string, used air as best I could to make sure everything was clear. After I was satisfied the body was clean I out the kit in it. Got the floats set to 13mm as per the manual (well 12.87 on one side and 12.92 on the other, so close), set the pilot to a little less than 2 1/2 turns out (manual says 2 3/8 turns). Put everything back together and tried to start it, it started and had a week idle. I tried adjusting the idle screw and as soon as I turned it the bike died. Backed it out and tried again, same result. Left it backed out, started it again and gave it some throttle. As soon as the throttle is touch the bike dies. Changed the spark plug for a new one and checked the spark, good and really strong.

I am thinking that I have a bad petcock and am not getting enough fuel to the carburetor. So when I press the throttle I am increasing air but starving for fuel, bike can't run on air alone so it dies. Does this line of thinking make sense? I am gearing up a bottle with a fuel line in it, so I can try gravity feeding fuel to the carb, just have to wait for the silicone to dry so won't be able to test till tomorrow. 

If it turns out to be a bad fuel valve, I will most likely just replace it with a universal one. If I go this route, what do I need to do with the breather line off the carburetor that used to go to the OEM petcock? Block it off or leave it open?

Any help, answers or other ideas of things to check would be greatly appreciated. I have a fishing trip at the end of the month and would love to have my bike running by then.

Sounds to  me  it is  too  lean . Try turning the  idle air  screw out a little  more. You  might also  pull the  carb apart again  and check for tiny  posts on the side  of the  the  tube the  main  jet needle is in.  One or more of those tiny orifices  could be  plugged. I  is  not starving  for  fuel   instantly  when  you  give it throttle ,  it  isn't getting the  right  mixture. That points to  a  blockage of  or  setting > make sure there is no  hole in the diaphragm  of the carb and the vacuum line and any  breathers  are routed and connected properly .

Petcock issue as I suspected, going to order a new one tomorrow. Hooked it up to a reservoir,turned on the choke and she started right up. Smoked like mad for the first 30-40 minutes or so, gassed me right out of the garage. I don't think it has ran for quite a while. Let it run for a bit, enriched the mix a little bit and now she's running smokeless. I've got the vacuum lines sealed off right now and am running it in prime. Got the rear end all back together tonight and took it for the first drive since I bought it. Its not perfect, but it was solid for the short 15-20 minute ride. Got a few more things to clean up tomorrow and will give it a bit longer test ride then.

No I was just doing ten posts so I could download a manual

I get that. And if you want to bad my I would understand that as well. I was just given a old quad by my boss.  I'm not totally sure I'm going to get into that much but I hope I do. I apologize for the inconvenience.

      2006 LT-F400F stator/generator cover change: What is the best way to check that all is good with the transfer operation before reassembling?
      By middlebrookgt
      I have replaced the cracked stator cover on my non-running 2006 LT-F400F that I purchased recently, checked all the shafts vs the service manual and pics and advice here.  I replaced missing gears, bushings and washers, made sure that truth marks were all aligned properly, that the shift cam springs felt like they returned properly, etc.  IAfter installing the new stator cover I checked the transfer lever for proper movement from L-H-R and then cranked it up.  Happily, it runs and changes gears well in L,  but it will not shift into H or R for anything.  I have opened it back up and am going back through it looking for the missing puzzle piece(s) but how can I best check that I have everything right this time before buttoning it back up?

      1991 quadrunner lt4wd rebuild issue
      By Joeguy
      Did a top end rebuild, honed .010 over, new piston, rings, valve seals, etc. When i re assembled i only had like 30 psi of compression but then after it sat all night i now it seems to have gained some somehow, there is much more resistance pulling it over and i even got it to fire for a few pops. Issue i got is that it makes a loud squeak noise through the intake i believe (goes away when throttled so something with carb area) and it seems to not want to run well. I took head cover back off and timing seems fine so im not sure if something is sticky and that's why i got some change over time or maybe the valve lash is messed up after doing all this, i did get another cam for it but i wouldnt think it would make enough difference to need to re lash. Any insight on next step would be appreciated, i will be looking up how to do lash on these because it is a very weird angle to slip a feeler gauge in. 
      Actually cam is slightly off now that i look at the picture, thought it was good while looking in person. Hmm.

      2000 Yamaha Big Bear Quit Today
      By Gwbarm
      I pulled out my Big Bear needed to do a few things probably havent been started in a year. Gassed it up charged the battery started right up. I have been using it around the property for this and that. Went to hook up my trailer to pull up to the house while it was idling it quit. Went to start it turned over but wouldnt start. After trying a few more times lost all power. Pulled it up to the house with the John Deere, the first thing i checked was the Universal fit soloenoil from Amazon and it was only a 10 AMP fuse so it does not universally fit the big bear it should be 30 AMP fuse. At the time i remember noticing it but forgot, at the time i had other problems like wiring harness being in a box stuck engine and no spark. when i bought it, yeah i know, thats one ishould have walked away from, but if i go to the trouble of hooking up my trailer and going there, its following me home.
      Thats old news, i still need to check it all out see if it lost spark and see if the starter shorted out it was acting kind of sluggish, i replaced the fuse with the spare 10 amp and blew immediately. I will try a 30 and see what happens.

      2007 Hond fore 500 4x4 es trouble after top end rebuild
      By Ejwill
      I rebuilt the top end on my 2007 Honda Trx500fe. It ran fine right after the rebuilt. But now when I try to crank it it blows Bach through the carburetor. I held my hand over the opening for the intake air and it blew gas back on my hand. Can figure out what happened all of a sudden. It was cranking and was able to ride it running through all the gears. Now can get it to crank just blowing gas back to the air filter. Need help again. Starting to think I should have walked away from this one.
