Hey y'all
I have been doing a tune up on my '62 Falcon with a 200 in it. I have Duraspark 2 and a YFA. I can tell it's been running rich,
When I installed the engine a few years ago I set the timing. For some reason it was at 18 degrees initial. I think this is because the balancer I had at the time was off.
So now that I've replaced the balancer and also have an advance timing light, I thought I'd revisit the timing. I set the initial to 12 degrees as I've read in the tuning info published on Classic Inlines and in the Mustang shop manual I have. I used the advance function of the timing light to check my total mechanical advance and total advance with vacuum added.
Total mechanical advance is 23 degrees at 3000 rippems. When I add the advance canister to ported vacuum on the YFA, the total advance is 42 degrees at 3000 rippems, which seems pretty high to me as those are FE specs and I always heard that timing was proportional to bore diameter. I was thinking to start at maybe 36 or 38 degrees and see if I needed to add any from there. I tried to adjust the canister to take some advance out but I can't feel an adjustment screw inside with a 3/32 allen key. I can feel resistance when I put in a 1/8 allen (almost the size of the tube on the canister) but I'm not sure if it's an adjustment screw. Turning it doesn't seem to have any effect.
Does anyone have a source or a part number for an adjustable vac advance canister for a DS-2 distributor? The only ones I can find are listed for v8 applications. I can find 6cyl vac canisters listed on Rock Auto but no mention of whether or not they're adjustable.
Thanks!
