New carb and possible upgrades
Working on getting my son's buggy back going.
I'm pretty sure it is a Roketa GK-28A-150. It has been sitting up for 1-2 years and the carb is going to need rebuilt or replaced. Is it worth stepping up to the 30mm carb, or should I just stay with the stock size? (26mm?) The jets are rusty, I haven't tried to remove them but I'm afraid they may strip. I have a high output coil, and was looking getting a new iridium spark plug, CDI, and UNI filter. It is all stock now. Where is the best place to get these? How do I tell if I have a AC or DC CDI? Thanks. |
A 30mm carb will be too much carb. Get you a can of Berryman carb dip from Wal-Mart or Oreilly's for about 15.00. Disassemble carb removing all rubber seals, put it in the dip and let soak overnight, remove rinse under warm water while scrubbing with a old toothbrush then blow out all orifices with 20-30psi compressed air. The CDI has 2 pigtails going to it. One will have either 3 or 4 wires the other 1 or 2 wires. If it has 2 wires it is AC if 1 wire DC. Give me a call 662-301-1563 and I'll tell you what you will need to get more power out of your buggy without having to buy parts that will not make a difference in performance. If I do not answer make sure you leave a message and I'll call you right back.

Thanks.
It has 1 wire so DC. I'll give you a call next week, I've got a lot going on over the next few days. |
A couple of pictures I took.

I saw several <$25 carbs on ebay.
Are these as good as the OE carb? Not worth buying? Or????? The carb dip recommended above is ~$20. I think it may be worth just buying a spare to have on hand. |
Also I was able to get the jets out.
It wasn't nearly as bad as I thought it would be. |
form what I know those are pretty much same as stock carbs I found a 26mm one with intake manifold for $27 though I decided to go wit a 26mm oko D slide, now about the oko and pretty much any slide carb from what I had read and heard and I am experiencing at this time is that they are hard to tune, however once tuned their performance is unmatched...

I would just buy a new replacement carb for the $30 bucks.

If your jets are that bad what about all the other small orifices that are brass, differently not worth the headache of cleaning each one out, I second the buy another carb motion. Can save hours of time and carb cleaner lol, Ive tuned lots of slide carbs on atvs n street bikes, but if you clean out carb and set air adjustable all the way down, then start turning it out till it idles right, warms up , then give it a run, see if it bogs, continue tuning screw for desired plug color. Long process but real snappy throttle.
