scrutinizer postlude and 440 timing
This is the c3ntral scrutiniz3r again. Hi, its me again.... the c3ntral_scruuuuuuuuuuuuuuuuuuuuuuuuuuutiniz3r....
Joe has ruined his SQJ37 nuclear powered roto plooker, and he's going to pay for it. The golden shower Must have shorted out his master circuit.

In efforts to discover why my RR was hesitating/bogging down under medium to heavy throttle, under load, I checked timing and vacuum to see what it was at. The motor seemed to be running fine, and gave no problems with acceleration under light load (slow acceleration through the gears was ok; getting on the gas caused car to trip and stumble). Unsure of what previous owner did to car (including any engine specs, other than its a E440 w/ cast iron intake, edelbrock carb, and has headers) I dont have a lot to go by.
I checked timing with the vacuum canister hooked up initially, and saw timing at idle that appeared (no timing tape on balancer, will be corrected next weekend) to be 30 or so degrees BDC. Removed the vacuum canister hose from the front right of the carb, idle dropped a bit, and timing now appeared to be right at 5 degrees After DC. Plugged the vacuum gage into the carb port that was connected to the distributor vacuum adv, and witnessed 15" -fairly steady, but ocassionally dropping to 12". The timing did not seem right to me, so (and obviously not knowing the right way to tune these monsters) I adjusted the distributor for roughly 6 degrees BDC at idle, with vacuum line removed. When I plugged vacuum canister back into the carb, idle raised several hundred RPM. Took the car for a test ride, and it felt Much better. The stumbling under load mostly disappeared. Now, I know it is not set right where it should be - the timing tab is somewhat hard to see, and with lack of tape on the balancer, its not very scientific. I have a timing question: I see lot of reference to "total timing" which seems to be in the area of 36 degrees for a 440 motor. Can someone enlighten me on the correct way to check, and adjust for this?
I have tried manipulating the capacitive reactance of the non-ferrus cavity in the elevation sub assemble (which looks just like a Telefunken U-47) to no avail. Apparently, the inverse relationship between altitude and capacitive reactance is not a factor in total timing.
