SBF 347, mild cam ...
OK, I think I figured out the linkage where I can now get cyl 2-3-5-6 sync close. Not perfect, but at least the car is running and all throttles look to be operating in sync. Bell crank connects to Driver front carb (#4), which connects to Driver rear carb(#3), which connects via hex bar to Passenger Rear carb (#1), which connects to Passenger Front carb (#2)
New plugs, Autolite 24. Tried to hear "best lean", not easy on cobra/daytona's
Used my timing light w/ tach on each cylinder to highest RPM. Ran car for 30 minutes, not too bad, no pops or major issues. Set the idle screw to 2000 RPM and tried the "best lean" using timing light w tach. Ran car back home and it started backfiring. Readjust again at 900 RPM using timing light/tach (over 1 hour of running time and 40 miles). Took car for drive on Sat, ran good after warm up, no pops, and seemed to respond well up to 6500rpm. Here are the plugs 1-4
#1 and #4 are dark and sooty. Should I lean out a bit (turn mixture screw in 1/8?)
#2 looks the best, but still a tiny bit lean. Leave alone?
#3 looks like white lean. Should I richen a bit (turn mixture screw out 1/8?)
use Autolite 24 vs ??? Tried Autolite Racing 13, Racing 25, and others.
Will pull drivers side plugs - got busy and a bit of a PIA.
Anyone ever hear or use the Colortune tool?
Thanks for your input
