i know on Yamahas the float level is about a 1/2" ... hold the carb in level position with the bowl removed, measure from the bottom of carb where bowl attaches to bottom of float, floas should drop to measurement and if it needs to be altered, the metal tang where the float pin is can be altered to the right height ...

      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.

      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?
      Thank you

      Our 1988 Yamaha Terra Pro is finally seeing the finish line of becoming our new bush hogging tractor! I've had the terra pro for almost 2 years... we had great intentions, but after removing the fenders, fuel tank, and the carb, we let it sit up. Shame on us! However, the terra pro is cranking today. We cleaned the carb, figured out what goes where and where did that screw go! She smokes like there's no tomorrow, but that's okay! The only issue right now is getting all these lines hooked back up to the carb right! There is 5 lines to hook up to this thing!! And in our moment of drinking and removing parts, we cant remember how they go back on. I've found several diagrams online, but none showing the overall schematics of all the lines! If anyone has a service manual, or any way of helping us figure out what goes where I would really appreciate it!! I can attach pictures later if it'll help!

      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.
      Strange.
      I never clean my carb because Im new to quad world and dont have the service manual...so I need you point of view.
      Thanks guys!

      Thanks if you could help me with that.
      Im new here so if I did something wrong, please tell me.
