That was going to be my next guess. There is alot of junk in these tanks that ruin filters but at least it had a filter. Like you said trial and error is the biggy with these quads but once all teh bugs are worked out they are great.

 

to me it still sounds like a carb adjustmentif you follow the guide by tomanytoys its a starting place you will still need to adjust a little more but not all that much sometimes alot of people overadjust to much...

did you clean the carb? you could have crap in it.

did you replace the fuel filter there cheap?

are you possible sucking some air at the intake ( where the carb bolts up) ?

ive been thru the same thing but once i got it.. it runs great.

what quad is it? 150 or 250 cc

the air cleaners they come with suck but...they will still run good with the crappy ones.
you can replace them with unifilter and then you will probably need to rejet the carb.

keep us posted we can help you. there is alot of trial and air like posted before but some here have seen it all you will get it going. and then you can finance a new one dont give up.

I know I am new to this, but I did check for possible blockage due to air in the lines, and noticed that once the line after the filter ran a bit slow I concluded that could be the problem. Apparently the dealer I got this from felt like giving me a crapped out filter to begin with. I of course "assumed" it had to be a bigger problem then what it really was. I was thinking it was a more problematic scenario, in the end, it cost me just over 2 bucks. I am more then happy with that. As for hoytultratec, try to take some idle out from the idle adjustment, once you have it warmed up. I did the step as you did and set it too high, just take it back a bit and find where it runs nice and smoothe. At least you know it's getting gas and able to run, the adjustments from their should be minor, of course this is just from what I've run into. I would take any adive 2manytoys has to offer. I have been browsing through here and the advice from him is honest and to the best of his knowledge. Good Luck.

 

khealy007 is having the problems, mine are running great. just need to pull a link out of the chain and all is good.

Ah, my bad, I was reading off the quote.

 

no problem, i really got them running good it took some tinkering but got them running good not bad little machines for the money my kid really has enjoyed them.

for me i will stick to my polaris.

I agree, they aren't really that bad. Plus I have learned, due to there being no other alternative. You get what you pay for. The machine is a toy for screwing around with and for the "kid",...... I enjoy it to of course. I would love nothing more then to get back to the good toys, but for the money, I can't argue with. Hey, there's always next tax season huh?

 

It's a 250CC Komoto. All that jetting and stuff you were talking about I've never done before. I got this for free and I would like to learn to ride on it. I mean, I can change the oil in my truck. Hell I even did the lift and exhaust myself but I've never messed with a carburetor before. Thanks a ton for all your help. I really appreciate it.

 

alright first thing i would do is.

take carb apart carefully and clean out with gumout blow out the jets they will run like crap with a tiny bit of junk in it.
do not touch any of adjusting screws yet. put it back together.

make sure air cleaner is clean.

put a new ngk plug in it.

start it up if it idles now you need to mess with the carb tuning.

this is where i would start its not difficult to do this just take your time. and make sure you have good not old gas in it.

keep us posted

CARB - taken apart, cleaned, re assembled and re installed.

Having taken this thing apart and put it back together I can tell you it's a complete and total piece of crap. The carb is missing bolts and the screws were mostly stripped. It was a complete and total biatch to do. Once I got all that done and put fresh gas in it and started it up it idled in the freaking RED. I don't know what else to do. Would changing the spark plug have that much to do with it? I didn't know what the NGK cross reference was so that is the only thing I didn't do. Any ideas of where I can go from here?
