Not linear. Never tried to accurately measure it. Have changed chain and
mpg improved by 5+% but the numbers I've seen are ALL over the place.
Too many variables. I have moved the actual pump timing of a well
running engine by almost 4 degrees and seen ABSOLUTELY no difference in
fuel economy. In an engine not running nearly so well, a change of 2
degrees resulted in detectable improvement in fuel economy.

Marshall,
While looking through the 126 engine manual there was an exploded view of
the chain along with various tensioning and slide rails and a chain
tensioner. When changing the chain is there any of these other parts a
person should consider changing or is the amount of work entailed not worth
it.
