sorry to double post.. but i thought of a few more things i'd like to add and i can't edit my last post : )
Quote:
The carburetor has three fuel openings (jets): Main, Pilot and Idle. It sound like the Pilot jet is clogged or there is a vacuum leak preventing the needle to move properly. Someone more familiar with your carburetor can give you specific information.
I drove it around some more tonight and really paid attention to how its responding to the throttle and i'm pretty certain theres some type of vacuum leak or one of the jets are clogged. The engine sounds good, but its laboring way too hard for the output. I really have to give it some gas to get it out of my garage. somethings just not right with it. The low end isnt converting, and sputters quite a bit and its not as noticeable when i give it more gas but there's something just not right. I have a turbo eclipse and it's acting similar to when i have had a vacuum leak in that. I checked all the hoses again and the only thing that I can't make sense of is the carb (pic below). I'm really hoping someone can show me a diagram of that particular carb or something similar to make sure its hooked up right. How do i check the jet to see if its clogged up? Thanks again, really trying to just get this thing running right : )
Your carb set up is the same as mine on my 2007 joyner 250. The two nipples that are disconnected (viewed in your first photo) are used to pass some coolant water thru the carb. The coolant is supplied by the capped off line coming from your temperature sensor housing. One disconnected nipple is water in, the other disconnected nipple is water out. I can't remember for sure where the water out line reconnected to the coolant system, but I think it is somewhere on the temperature sensor housing also. We suspect this set up was used to meet some emissions regulations, and most people disconnect it anyway because we don't want to heat up our carbs which reduces performance.
The coolant not passing through your carb would not cause the condition you are experiencing, but the bigger question is who disconnected this line on a brand new buggy? This is not a part that fell off, it is a modification. It is quite likely that this would be a modification that voids the warranty.
As for the poor running condition, look at the air intake housing where it attaches to the carb. The intake is very poorly constructed where the rubber sleeve is glued to the plastic housing. Consider taking the entire air filter assembly off and replacing with a K & N filter attached directly to the carb. Of course this may also void your warranty.
I suggest you look all over the carb and see if you can find the manufacture's name anywhere. It looks just like the standard carb that came on mine. I really doubt it's a Mukini. Also the 15 hr. thing sounds like a line of muck muck to me. If such a device exists, why has only one lonely chinese manufacture decided to use it, and not all the major manufactures like Polaris, Honda, etc.
If in fact there has been a modification made to the buggy prior to your receiving it, I would demand that the dealer allow you to return the buggy, and that they pay all shipping costs. _________________ JEHM 150, Joyner 250, Roketa 800

Thanks for posting those pics BIGE. I'm unable to tell if its the same carb I have or not.. It looks similar in the first one, but i can't really tell from the second pic. Regardless thanks for posting them.

I took the airbox off to get a better look at the carb and found "KF Standard of Japan" Which is of Keihin Fuel Systems. And it has HE13JL14 stamped on it. The only constant velocity carb by Keihin I saw was the CVK40, but i'm by no means certain this is the model. However I am pretty certain it is a Keihin and not a Mikuni carb... I called gokartsusa and he tried to tell me keihin is manufactued by mikuni? Yeah right. If its a mikuni carb why doesnt it say mikuni? He was rude and directed me to the 'technical support' portion of their site which submits a 500 character ticket to their 'technical support'. He promptly 'thanked me for calling' and hung up.

I definitely didnt take the hoses off and put the screw in that other hose.. Who would have done this? The factory?? Why?? It sounds like the dealer hasn't even seen this kart, and it was just drop shipped from the factory so I dont think they did it. Didn't sound like i was going to make much headway with the guy i talked to on this issue..
If it isnt a mikuni carb I want them to send me the one they advertised, have someone install it and make sure everything is running perfectly on their dime.
Disconnecting the hoses is definately not something the factory would have done. I would say that the buggy was either sold before or used by the dealer you bought it from. This dealer is giving you a big line of CRAP. I would demand that they take the buggy back, with no expense to you. Let them know that you are posting their actions on Buugy News, which will not kill there business, but sure won't help. Contact the BBB in your town and the dealer's town and file a complaint. I would also let the dealer know that you will be contacting the State Attorney General in their state to let them know that they are selling used equipment as new, or making modifications that void the warranty. _________________ JEHM 150, Joyner 250, Roketa 800

what rockrunner said would probably be the best thing to do. I do not think you have a mikuni carb, the stamping on the side just about says that. _________________ Blade buggies,Carter buggy's, ams (manco) , joyner, parts for almost anything

Whats weird is it 'seemed' new.. the tires and what not, there wasn't any ware or tear on anything. I believe there was some reminance of gas in the lines however.. And coolant in the radiator. I assumed they had just tested it at the factory. These guys seem shady, and i doubt they're just going to 'oh we're sorry we'll take it back for a full refund' which is why i was kind of hoping to just get a new carb and have them pay to get it put in and have everything checked (because i do like the buggy..) but you guys are right.. its just wrong. and i'm pretty sure after the guy hung up on me that he knows i'm on to him and hes probably prepared for me to call back tomorrow and let him know that i didn't forget they gave me the wrong carb... so my guess is they'll say they did nothing wrong and i really will have to take it to the bbb and the state attorney general.

exactly.. once i told him it wasnt a mikuni all he could say is 'i dont know what to tell you. its a mikuni.' 'why doesnt it say mikuni' -silence-..
