Gas Mileage???

@rmchrgr I think you understood me wrong.. I meant 10 deg @ idle...and 25 deg. advance on top...so 35 deg. all in.. at 4000 rpm.. ( yes I know the curve is slow..but the enginge pulls very very strong .. sadly the vacuum canister... only works well under WOT and off the line. The 50-60 mph ratteling is still there.... ( Made some test runs today )

@all
Next I changed the VC from Ported to Full Manifold Vacuum.. Great for a smooth idle..( 20 deg )
but that it... 50-60 mph rattteling...

So I changed the set up again.... 16 deg. @ idle and 18 deg advance...all in @
3500 rpm.... still a little rattleing...at 50 -55 mph without load... Frustrating !!
Beside this "50-60 mph problem " the engine pulls strong also...

I know now...that the engine doesn´t want more than 25 deg of advance @ 2400 /2500 rpm....

Is that normal ??
