Cool Dave’s 1973 Dodge D100 Club Cab
Alright so small update..
Pulled the EGR valve, it actually had a hairline crack between the two ports. Cut out a metal block off plate out of some shim-stock, sandwiched it in with a skimming of high-temp silicone.
Then over to the distributor side.. moved the vac advance line to the ported vacuum on the carb.
I also managed to craft a new connection/wire for my choke assembly so I repaired that and got it back on.
On the timing I do not have a functioning tach or a timing light that reads RPM. I set the idle timing with the vacuum kinked off to right around 5-6* initial. I’m not sure what RPM it is at but the mechanical maxes out at 28-29* according to my Harbor Freight timing gun.
With these numbers locked down I unkinked the vacuum line, it didn’t seem to make any noticeable difference to idle but it did certainly help the low-throttle driveability and idle temperature. I still need to replace the can on there regardless.
One thing I did notice with my timing gun, is that sporadically I would get a timing jump of 3-5* but only for a split second and then it’s back in line, not consistent or engine speed dependent. Typical culprits to check?
