300 power (or not)
My truck is an 86 f150 4x4, 4.9 six cyl.
I feel that it is down on power, but others I've asked say it's not. But climbing the mountains it often cannot maintain the speed limit.
The compression is good. The iginiton is all new, plugs wires cap module etc. I even checked the cam timing and it is good with minimal play.
It is a California spec vehicle and has the one bbl carb.
At first I was looking for a crank sensor that would be used for the timing control but cannot find any reference in my manual on on the engine.
I did record 16 mpg at best but it is usually more like 12mpg.
Is this just the way these things run? What am I missing?
