Bought a CS .28 to see if it could be used for speed limit combat, as an R/C engine this thing is complete garbage I say that because the carb on it did not function at all, it leaked air so bad that with the needle closed tight it still ran rich...lol I kid you not
So I replaced it with LA carb and it ran beautifully, ran two 6 oz. tanks through it and now it starts in 1 or 2 flips every time, next I need to mod a LA .25 venturi by drilling a small hole and installing a piece of tubing so I can use a remote needle other than that so far so good but boy I feel sorry for anyone who buys this thing as an R/C engine.
