The thing sat since Christmas 2018 and while I decided whether to replace the starter (which I finally did today). I am not sure if I added fuel stabilizer or not but chances are good I did. I kept the one year-old battery well charged during the winter. It turns over well but won't start. I have a blue spark on a brand new plug. When I pour a bit of fuel down the cylinder, the engine starts and runs for a few seconds (once for as long as about 8 sections) and then dies. Even before adding fuel to the cylinder I noticed that the spark plug was wet with fuel.
The air filter looks a bit dirty so I removed it just to see if the engine would start better but it made no difference.
If the fuel did not contain stabilizer then the carb may be gummed up. I don't really want to remove the carb to do a thorough cleaning. Is there a product I can spray into the carb while the engine turns over that will clean the carb?
Any other suggestions?

Recently, Jonathan has been repairing & reassembling a client's 1983 Big Red Honda ATC200E. In this video, he gives an overview of how he approached diagnosing the ATC and creating a plan for the project.
I wanted to share an experience and a fix.
Headed out was following a pole line, was looking for a cross track that may take me to this speckle trout looking spot on a creek. All paths and semi paths... failed. Second objective was to reach a speckle trout lake that has been recently stocked... followed 1 trail to dead end, followed second trail to dead end.... while investigating options on foot and the quad idling it died.
It wouldn't start. eventually it did... and when it did … it was essentially a pinned idle. activating the throttle did seem to speed it up but it wouldn't knock out of the racing idle. couldn't put it in gear at that idle speed. got towed out.
when I first got the quad, I ran it off a trail and buried it pretty good in the soft snow... eventually winched out. It wouldn't start. eventually did and it was fast idling. not as fast as this last time. but still fast. it eventually seemed to settle and I got it in gear and by the time I was back to the truck was acting ok. chalked it up to the bike being at a bad angle in the snow.
My investigation last year lead to the throttle position sensor TPS. how to jumper the diag block to see the sensor position on the display,. I focused on this nearly sure it was a detuned sensor or broken sensor again this time.
I tore down the front plastic and stuck my head into the TPS area to see what I could see. What I found was that the throttle body assembly had actually come out of the mounting area (not sure what it is called). the ring clamp was loose I could move it easily. Hopeful, I tore down the air intake assembly above it (air filter...etc) removed a sensor clip and a hose.
I backed off the clamp some more and was able to reseat the throttle body assembly. put some blue lock tite on the clamp screw. When I was cleaning off the air intake assembly to ensure I dropped nothing down the intake, I noticed the underside of the air intake "box" also had a clamp. this screw was completely missing.
I went to the hardware store, bought a metric replacement (brought clamp with me), seated the assembly, settled the clamp blue lock tite that as well...
quad fired right up, idled normal, idled up without hesitation and dropped right back off. Cost of solution $3.87 CND for a pack of 5 metric screws. moral of my story was don't assume an idle issue is a throttle position sensor problem... there are a number of other factors including air pressure, which I believe was my issue.

I just recently bought a 1994 Yamaha Timberwolf 4x4 from a buddy who had the wheeler sitting in his garage for 7 years. I got it home and fired it up pushed it out of the garage and tried to shift it and it wouldn't shift. First it would click like it was shifting, but the wheeler wouldn't move and when I hit the gas it revved up like I was in nuetral. After trying some more it became stuck in 1st gear and wouldnt shift at all. But it later broke loose agian and acts like it is in neutral again. I took the motor off the machine to make it easier to work on.After asking friends they were convinced it was a clutch problem but after opening up the casing for the clutch I don't see anything out of the ordinary and am concerned that it may be a transmission problem. Any help would be greatly appreciated thank you.
Hi all, my second post here
I got an old Yamaha 88 moto 4 and I have a problem with my overflow hose from the carb.
When I put the gas switch to ON a big amount of gas is leaking from the overflow...so I start using my quad with the gas switch to RESERVE wich is also leaking but less than in ON position.
I dont ride a lot..but in a week I empty my gas tank.
I never clean my carb because Im new to quad world and dont have the service manual...so I need you point of view.
Life got the best of me this year and to make a long story short my '11 Grizz 700 has a half tank of gas (w/ no stabilizer) and hasn't been started for around 9 or 10 months. I have apologized to it and promised this will never happen again, but in the meantime I'm faced with what to do to remedy the problem. Ideally I suppose I should get the tank off and drain the gas, replacing with non-EtOH gas (which thankfully I just found in my area).
Any advice on how to get this done (draining the tank) or how difficult it might be?
hey I'm dave westfall I'm new I just became an official member of this site a few minutes ago. Ive been crazy about quads and bikes since I was about 3 and ive always done my home work on them figuratively speaking. I would say for comparison to the common man that I am pretty knowledgeable about them. its been my passion about most of my life. I love talking about quads and bikes so if anyone out there would like to talk with me about mechanical subjects or about person experiences while riding or just shoot the breeze please feel free to chat with me. I'm looking forward to it.
