17-18 with a fresh 22r
is it rebuilt and did you bore it or otherwise rod the engine???
i see this pattern with rebuilds getting worse mileage that old originals so i'm curious
yup, total rebuild with max bore pistons. 10:1 c/r. mild cam, header,weber carb. recrve dist. over sized exh. valves. hummmm, thats all the big stuff.
I know I could do better on MPG if I drove slower
