ALCOHOL DOMINATOR , WHAT IS A GOOD JET STARTING POINT???
 

HI EVERYBODY , I HAVE A 555 BBC NESSBIT MOTOR , 15-1 COMPRESSION, I EM GOING TO USE AN 1150 ALCOHOL DOMINATOR, THE MOTOR MAKES ABOUT 820 HP AT THE CRANK IN MY ALTTITUDE ..WHAT IS A GOOD START POINT FOR THE JETS, WHAT SIZE OF JETS SHOULD I START WITH TO BE SAFE . I DONT WANT TO MILK THE OIL AND ALSO DONT WANNA LEAN IT OUT , ANY IDEAS WILL BE APPRECIATED, THANK YOU :D :D

What brand carb? I ask because I know each builder is a little different. For instance with my Rupert carb that is very fat on the idle circuit I have 161's in my carb. With the APD carb that is lean on the idle circuit I would look at 196-200 on the jets. This would be a 1250 on a 582.

THANK YOU SHAWNP , MY CARB IS A ---- J.E.R. ---- JIM EVANS RACING 1150 , THANKS

178's, Idle mixture screws out 2.5

thanks for all the info guys, got ahold of jim evans of jim evans racing , he guy who built the carb. he said start at 218 jet ,,and go up from there ..i guess every alcohol carb is different. :D :D
