1997 Yamaha Timberwolf fuel line clogged

Recommended Posts

I'm new here an hoping for fast help. I have a 1997 4x4 Timberline 250 that is my major helper here on the farm. We have had a tough winter so far and the machine is already struggling (another story) with a terrible oil leak (the case is cracked...I will need to find another engine this spring).

After cleaning the last round of snow last week (deeply sub-zero) I pulled the ATV into the barn. It has been in here during the recent extremely warm weather until last night when I pulled it out to get ready for this current and fast approaching weather. The temps dropped day before yesterday to normal below freezing and my son-in-law thinks condensation could have frozen in the line. I could not get the ATV to start at all and ended up pulling it out of the barn by hand, rolling it down to the front gates in preparation for work (I assumed I would eventually get it started!). My son-in-law was just here to get his son and said no gas is coming through the gas line (from the tank). He has added a full bottle of HEAT and changed the spark plug but had to get to his family while he can.

I am about to be hit with up to 15" of snow and the ATV, while covered, is at the gate and the only method I have of cleaning the coming blanket. I am alone here for the week and may not be able to get out of here within the next couple hours.

How long will the HEAT take to open a frozen line? If this is not the problem, is there anything else you can think of that I could do? I cannot get the ATV back in the barn and I am certainly not qualified to do major gas tank surgery. My neighbor was just here and said to get on the ATV and jump up and down -shaking it liberally- every now and then in order to dislodge any ice crystals or debris. HELP!

Welcome to QUADCRAZY. I have seen on some Yamaha atvs, corroded and stuck float pins in the carb causing no fuel flow. If you could get to the carb and remove it enough to take off the bowl, inspect the float. I suppose it could be a frozen fuel line, but it would have thawed out when you had the warm weather.

* Moved thread to Yamaha forum and added year and manufacturer to thread title.

Take the line off at the petcock and see if fuel will come through the petcock when you turn the vavle to the on or reserve position. If it will come out of the petcock, but won't come out the other end of the line, then I might try blowing compressed air through the line, or just replacing it. Fuel line is cheap. If it won't come through the petcock, try blowing compressed air through the petcock into the tank with the valve in the on position and again with it in the reserve position. Make sure the cap is on the tank when you do that, and be ready to shut the valve off incase the fuel starts coming out. Also, check the tank for debris floating around in there, if you see stuff in the tank, you will want to drain it and clean it out.

I did remove the line from the petcock and moved the switch but nothing came out. That is a very good idea about the compressor though. I'll get the compressor and extension cords on the sled and down to the ATV and try that!

don't run pump gas anymore- it has so much crap added to it that it is actually hygroscopic.

Here we can get non-ethanol super at the gas station pumps- it works great and is cheaper than race fuel, which is not gasoline at all.

regular pump gas will dry out any rubber part it touches- it's a bad deal for anything that's not brand new.

You can pull the screws out of the petcock and drain the tank if nothing else- this way you can examine that petcock and hopefully clean it out.

Grab one of those $2 inline fuel filters next trip to the bike shop- try not to run anything with ethanol in it- often available at the bulk plant but take a gas can cuz they generally pump it out of a drum. With good fuel you'll notice an increase in performance too- it made my pickup run better! LOL

try fuel injection cleaner- it is more $ but usually works a lot better and faster than HEET.

Hope this helps!

      Hey, I just bought the kids a LT80 and noticed a small puddle under the machine after they were riding it for a bit. I'm wondering if anyone knows why the fluid coming from the fuel shut off is a red colour, and would have any ideas of where this issue is coming from? I haven't had a real good look at it yet, thought I would ask first.

      Hello all, I’m working on my sons 99 Yamaha Warrior 350. When I pulled the plastic cover off left side of engine, I can see oil leak at the seal. I pulled the bolt out and then the starter boss(I guess that’s what it’s called?) I can see that the boss doesn’t make contact with the seal. Is there a spacer of some type that slides on to the boss, to make contact with the seal? This seal is held in place with a plate with 3 screws in it. This boss slides into the bearing in the stator. I have been to parts websites and I don’t see what I’m needing. Maybe it’s just the wrong seal?

      Hey I'm new to the Forum but I just wanted to talk about my Scrambler I just picked up and when I first picked it up I thought it was okay but after I got home and everything I noticed it's very hard to shift into drive neutral reverse it is possible to shift into those gears but it's very stiff like and it takes a lot for it to actually engage to move forward. In Drive when I press on the gas it takes a while for it to actually start moving in the RPMs go up before it starts moving I inspected the belt it looks fine to me I checked the transmission fluid and it was low so I put some. I just hope transmission is not out just curious if you guys have any ideas

      My 2005 Arctic Cat 500 started leaking fuel from the top right hand side of the carb. It looks and feels that the fuel is coming from under the throttle cable housing area just above the primer pump. I have not had time to take carb off. Has anyone had a leak on this side and area of their carb?

      HELP, i have a 2009 yamaha grizzly 700 yfm7fgpy special edition with a defective fuel pump and am wanting to know how to test it to know if it is defective or not

      I have a timberwolf that I love. It sat and the carb got gel from this wonderful ethanol. I cleaned it and put a new kit in it. it always started right off. now it cranks forever before it hits and then it will not idle. set according to instructions 23mm float, 4th notch on the pin, 1 1/2 turns out on the AIS. I have tried tweeking all of these some but nothing seems to make a difference. The biggest problem is that I got it back out because the wife has claimed this bike and now it will not run for her. Any help would sure get me out of a bind.

      Alright so excuse the ignorance but this is my first carb break down. Got it broke down and cleaned good. But now my problem. I am not sure where to start on adjusting my jets and air fuel mix. Any help on factory settings as a starting point would be great. I have a general knowledge of how it functions and terminology I just need to know where to start
