I take that back. WOW prices have really went up on certain products! A couple yrs ago the carb i bought was half.the price it is now! Same with the ncy heads. Thats sucks. So maybe you cant get it for 30- 40 bucks more like 60-80.

My Runtong cvk pumper carb has a multi peice jet or tube the jet conects to and this also has pinholes up the tube which alows the air to prematurely mix with the fuel, unlike your basic carb. So yes this is a true cvk carb and they are the same ones they sell on ebay. Also the piston on this carb is not directly connected to the throttle like your basic carb.

The only reason I do not like the cvk's well theres a few reasons. I dont like the auto chokes, I like simplicity and don't mind pulling up on the little choke if I have to ( i live in Florida ) so even in winter it is very unlikely I will need it. Everyone says the cvk's are easier to tune but I beg to differ, never liked them.
My 2008 ktm had a keihin fcr 39 and it was one of the easiest things to tune, but also I was thinking if this 37-40hp full mod 250 runs great on a 39mm do I really need even a 30mm to feed a maybe 15hp 150-205cc engine. I think the 28mm will work fine, ill get it tuned it for the stock engine and keep an assortment of needles and jets around to tune as mods happen. If I happen to get into doing a turbo ill look at the EFI system at that point or if I go 232 ill look at a 30-32mm at that time.

the CVK carbs are great. but the flatside carburetor is such a simple carburetor and its an instant throttle response because when you twist the throttle you raise the needle. unlike CVK or stock carbs. some prefer the flatsides some prefer the CVK pumpers.
