Does any one know the proper adjustments for all the jets in the carb., I just replaced all the jets and I'm getting a lot of backfire also it seems like it isn't getting fuel or bugs down while idling and or riding any help would be great. Thanks

Hey gator man. Are the new jets oem parts or aftermarket? The jets as far as I know are seated until tight and just a small bit of pressure to make sure they will not come loose. Now as far as adjustment I believe there should be only two screws for adjustment.  1 is the air/fuel mixture screw.  This should be turned until snug and then bring it out about 2 and 1/2 turns and leave it there.  The next one is the idle screw and that should be adjusted once the bike is running.   

The air/fuel screw should be slightly adjusted once the bike is running  maybe a quarter turn more out or in and can be determined after you take a ride and see how she runs. 

Was the carb in bad shape and dirty? 

Also with regard to the jets and  mixture screw were the springs and o ring in place  on the air/fuel screw ?

      Hopefully someone can help me out, I purchased a 350 moto4 2wd while I'm trying to fix a dying honda. I can't see the vin number as there was damage and a bar has been welded where I think the vin should be, The decals say 350 moto4 Huntaway, it has the square gear change low, high, reverse up on the left of the handlebars and it has three rectangle lights up on the dash. after googling I'm struggling to find anything called huntaway, Any ideas? Thanks.

      I get it, turn counterclockwise will decrease, turn clockwise will increase.  My question is what exactly am i increasing or decreasing? Is it clutch pressure? In many videos i've seen it's always "turn counterclockwise" until you feel resistance then back off. Why is it always to decrease? 
      I'm just curious as to what exactly is going on when i turn that screw right or left. And, since there's no manual clutch to engage or disengage, what is going on inside? 
      Reason why i'm asking is while going down a hill in 1st gear, it appears to pops out of gear, but no neutral light, and if i stop, it's in 1st gear still. BUT, (always a but) if the engine is warmed up, it stays in 1st gear. The hill is too steep to use any other gear, so 1st with the brakes is the only way to go down.

      Just aquired this Honda 4514. I had heard of them and seen them but had never really looked at one. Amazing machine from the 90s.
      It has a 14 HP inline 2 cylinder engine. A cute little fan like the old school cars had and a little radiator. It has a timing belt on the back of the engine running the cam and a water pump. Just like a miniature car engine with  electronic clutches to turn blades on and off. Pretty hight tech for the 90s not a small thing and built like a tank weighs in at 600 pds hydrostatic trans. I have found out that almost anything you have to do to it the engine has to come out starter timing belt water pump. Very expensive parts i think most got junked for that reason, i did find out they were built by John Deere except for the honda engine.
      Does anyone here have any expierience with these.

      My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area. 
      Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.
