Compression 140-160 1971

Taking into account all suggestions

1.Switched plugs as per B20paul...better...no Knock, less dieseling
2. reset timing at 13...reconnected vacuum advance
3. Changed to 195 mains...installed UEGO gauge for AFR reading

Reads 13.2 at idle (1000)
Goes "out of range" rich when first getting on it then drops into 15's and 16's if you stay in it...back to 14.2-14.5 at cruise.

I can raise the needles two more slots...or do I need a bigger main? Or do I shape the needle somehow to add more at 1/4 to 1/2 throttle?
