Just bought the great dane chariot last tues evening. with .5 hours on it. As of monday my bro and I noticed heavy smoke coming out of the exhaust and flame shooting out of the tip (steady not a pop). Took it to the dealer, with only just under 2 hours on the engine and we get a call yesterday telling us the engine has a weak cylinder, possibley the rings or what have you there were some other little things duscussed also. I cant beleive this I;m having nightmares of the 25hp kohler now. I knew i should have bought a diesel. Supposed to get a new engine put in we will see.
