Question for the carb guys !!!
what are the correct jet and metering rod sizes for a Rochester MV single barrel carb.... Ive got a 106 jet and a .073 rod... my prolem is only bout 13 mpg with the straight six (250) and 3.73 gear with 3 on tree... it runs and idles mint with 22 in/hg vaccuum... i looked up figures in my haynes and got .080 for the rod and 95 on the jet... something doesnt make sense... it also is a hard starter, both before and after the rebuild on the carb AND when i take the airhorn off the carb after sitting a night the fuel bowl is dry... any xperiences??? this is puzzling me.... thanks in advance for the help...
