best way to set it is -start by pinching the fuel line about 2 inches up going into the carb and it should die after 4 to 5 sec. it is hard to explain because it takes a trained ear but, just count for starters. then the bottom should be set. then set the top for temps you can start at about 3 full turns out from closed on top. then get it up to about 230 or 250. it should smoke but not too much. if it seeems to baug out- lean the top out in 1/8turns. remember it is always better to run it FAT -rich first...
