ive heard of those and some refer to it as (oh no)
unsure what they mean

[jplltz50]

you should know what they mean, you sold me one of those p.o.s carbs last month when i posted "wtb a sunworld 16mm carb" still waiting for my money back, paypal has to sort it out cause you wont do the right thing.

i posted back in january for a sunworld 16mm carb, in fact the ad said wtb sunworld 16mm carb for drr 50, fomospeed replys with i have a 08 pull off little use etc, now because he responded to my ad, i can only come to the conclusion he has a sunworld carb. i waited 2 weeks for delivery because" someone forgot to send", when i open the box it was a oko 21mm carb. i emailed as soon as i saw it and ask if he sent the wrong carb by mistake and the response he gave was "it what i said it was an 08 pull off". why would you respond to an ad for a carb that you dont have to sell!!!!!!!!!!!!!! i tried to work with the guy and told him ill eat shipping back if he refunds my carb cost and shipping, but he thinks for some reason this is my fault and wants to give partial refund. paypal has the dispute now.

watch this guy hes shady

Ok, don't know what the p???ing match is about.all I want is info on starting point! I'm just putting together a practice motor together. Bought two used cyl., borrowing the carb, to see if I want it or buy another pwk. Don't have my motor or carb it's being worked on for nationals. To get an idea were to start, pwk on other motor is 19mm though.
Main is 90, pilot is 35

i would try a 120 or the fatest main you have and work your way down thats the saftes way and keep an eye on your plug

which pipe on that 50 with the 21mm carb? if its the 90cc DRR pipe, then start with 120 main and 40 pilot.

Apex 70- 90 pipe. Going to have to wait till Monday to get more mains put 125 in, and no bottom end.

are you just puting the motor together with a bigger pipe you may have to change the wghts also if you are i would throw that 90 main jet you have in it just to see how it feels just run it a few feet dont leave it in long it may be to small you dont want to over heat your cyclinder plus your weather will play a big factor in jetting also check out www.roost.si they have a tuning procedure and you can go under www.miniQuadsRacing OR HOTQUADS FOR tech help thery also have a carb tuning
