Pictured are the tubes for your fuel vacuum activators. You might not have the horn in the center depending on your fuel tank valve.

In the back top, two vent hoses that route up underneath the shift lever panel.

Fuel feed goes in lower left near the bowl.

Tim : thanx alot ! i dont understand all the extra hoses? as they go nowhere ? venting maybe? jim

Fuel pump should be on the upper left frame fwd of the handle bars. It is the vacuum that operates the pump.

You might not have the fuel tank valve port on your carb. If your tank valve is the simple on, off, res, type, you don’t need this. If it is the on, pri, res, type, then there is a vacuum port on the back side of it. Vacuum from the carb opens this type valve to allow fuel to flow to the pump.

If you have the simple valve with a carb that has the fuel valve port, plug the carb port. It is not needed.

Do you have a manual for this machine?

Hi tim: i have another issue with the same machine! i cant get a spark,changed the stator,ign coil and the voltage regulator. checked and checked everything twice and still nothing? here is my question, the wires on the stator dont match whats inthe manual? can you tellme where ea wire goes using the colors? and also on the voltage regulator,there are 3 yellow wires,the manual does not say to what wire(color) they go to or does it matter? and does the reverse switch have to be connected for it to start? if so where do they connect to and the colors,please!!!!!!!!!!!! i have checked the cdi and it checks out ok. thanx jim

      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!!

      I WANTED TO UPGRADE THE CARBURATOR ON MY 1992 BIG BEAR 350, SO I ORDERED A NEW CARB FROM EBAY.  ACCORDING TO THE WRITE-UP IT WAS A GOOD FIT FOR BIG BEARS FROM 1988 TO 1996.  WHEN I REMOVED MY ORIGINAL CARB I NOTICED THAT IT WAS DIFFERENT FROM THE NEW CARB MY CARB HAD TWO THROTTLE  CABLES THE NEW CARB ONLY HAD ONE CABLE.  HOW CAN I MAKE THIS CARB WORK ON MY TWO CABLE THROTTLE?

      Hello I’m new here and was wondering is anyone knew of good replacement part numbers for front struts and rear shocks for this atv? I think I’ve found a new rear shock, that looks like the original but there is no dimensions or anything and was wondering if there are any afterMarket new front struts available. I know it’s a long shot but any help would be appreciated.

      1996 4x4 Timberwolf rearend width. Can someone with some knowledge of these machines answer this question for me please. Are all 4x4 timberwolves this narrow in the rearend? These tires are so close the right one actually rubs the muffler.  Thinking about seeing if there are any spacers out there for it. I need at least an inch more clearance.

      I have a 1988 Quadrunner 250 2wd. My brother in law sold it to my son for $20...had been sitting outside for several years. Got it home and had it running in about 30 mins. Ran it a bit and then went to looking at the carb as it was having trouble idling. Was getting it pretty close, then started losing spark...Also, it wouldn't start up every time...only about 1 in 5 tries. Anyway...now, it has what I can only describe as "intermittent" spark. I can get 1 light spark right when the start button is pressed and sometimes one when it's released...but none while cranking. 🤷‍♂️

      I have replaced the spark plug, ignition coil/wire, and traced wires best I can. I noticed a couple frayed wires at the pickup coil where it enters the case. So, now I have the cover off, stator and pickup coil out and trying to test the coil. I do have about 114 ohms resistance for pickup best I can tell. And I can read minute voltage when I drag a magnet across it. Could it still be bad? Can a bad ignition switch/button cause this? (I did have the switch off to oil the choke cable)...pulling rope makes no difference though...any ideas or help would be greatly appreciated!!! It's the intermittent part that's throwing me off!
