Sounds like a couple of things are going on. You really need to know what carb you have, clean it and tune it with the right jets. Amal and Mikuni jets are not interchangeable. Can you get us a pic? Check out this Mikuni manual for tuning: http://tinytim.forumcircle.com/viewtopic.php?t=1604&
True. The manual (3rd link) is for a VM and it won't match the CV carb. But there's lots of good basics there on how a carb functions, regardless of type. For the CV carb, check out the gallery and search for ucal. To me the video sounds like the carb needs a good clean and tune.
I just bought this battery and after 200 miles it seems to be working great... it's ten bucks on amazon with another ten bucks shipping.http://www.google.com/search?client=safari&rls=en&q=YT4B-BS+AGM&ie=UTF-8&oe=UTF-8It's a battery for a little 50cc scooter, but it seems to work just fine for kick-only motorcycles.
Too late. The en-ess-ay already logged it into their data base and will forever know you want to change your battery.
Update--Pulled the carburetor off today for cleaning, and to see just how it was jetted. Continuing on the odd train, it looks like the main jet is a 130 (!). Didn't get a good look at the pilot jet. Honestly, I'm not even sure it was marked. Thanks guys,RP
Update--Idled fine after I pulled the enricher (choke knob) out all the way. Thanks guys,RP
Update--Tried messing around with the airscrew (little flathead screw under the brass throttle plate, right?) to get the idle to sound right-- it didn't like that and died with a bit of dusty smoke from the air filter. Huh. Thanks guys,RP
Update--Also, in regards to the air screw, how tight is tightened all the way? When I tighten it to where it feels like it was before, seems like I hit a small spring (bit of a creaking sound). Should I keep twisting until it's locked down all the way before backing it off, or is the spring the extent of how far I should screw the airscrew in?Thanks guys,RP
