FoxBansheeRacing Posted January 30, 2004 Report Posted January 30, 2004 I have a 35mm 2 into 1 carb that I will be installing soon and I have heard that the power jet makes them run inconsistant. Should I shut it completely off and just run bigger mains? I am 500-1000ft above sea level in 30 degree weather, so how should I jet it. I got a 178, 180, 185 and whatever main is in it right now. Will one of these work or will I be ordering new ones? Quote
Banchetta Posted January 30, 2004 Report Posted January 30, 2004 Start w/ 185 and work down, better to start rich... Quote
sredish Posted January 30, 2004 Report Posted January 30, 2004 I'm trying to remember, and I'm fairly certain I have a 180 main in my machine. Its a little rich for this time of the year, but the weather fluctuates so much that trying to jet for the conditions would be a weekly occurence. I can handle a little smoke now and them. Like Banchetta mentioned start with the 185 and work down if need be. I'd imagine the 180 will work for you given the time of the year. I wouldn't doubt over the summer needing to go somewhat richer, maybe 185. Good luck and keep us informed. Quote

sredish Posted February 2, 2004 Report Posted February 2, 2004 Yeah, sorry. I always get this winter/summer crap confused. I've still got it backwards. I run a 180 in the summer, and the change is so minor here that I left it in for the winter, and mixed a 32:1 mixture (usually a 40:1). Quote
