need 48ida tuning help. 13b 4p 1/2bridge
Hey guys, car is running well but REALLY needs the carb tuned. running rich right now with a 48ida from RB for a bridgeport 13b i bought from another member hear. I figured it would work but knew it wouldnt run perfect on my engine
ran well enough to get me to and from the east coast rotary classic this past weekend in VA beach. rather run rich than lean... at least for a little while until i get her perfect
my engine:
12a irons
gslse housings
half bridgeport
s5 na rotors
48ida obviously...
full dual RB exhaust
i "think" it has
Fuel Jet - No. 235
Air Jet - No. 165 •
Emulsion tube F-11
when i got it i was prepping for a show so i just threw it on there and was excited since my engine was done. Putting in a aem a/f gauge today. i'll have 2 bungs on the dual exhaust and only 1 gauge so i'll be switching it a good amount to confirm both rotors are running the same (i understand one is bridged so they will require some different tuning).
my question, to start with the tuning what size jets should i order ? i was thinking around 220 fuel and 155 air or somewhere in that area? maybe an F-7 or should i stick with the F-11? thanks for the help!
here's 2 pics of her
1) no it doesnt get hot, i have a shield around the exhuast and the carpet was removed over the weekend.
2) loud? naw it's not too bad.

Don't guess. Wait until you get your A/F meter working. Once you have your meter working, then pay close attention to your foot (throttle open amount) and the rpms at which you get your A/F readings. Then we can figure out what to do with your jetting.
