Answer to One of the Re: <VV> Two Questions

[Andy Clark]

Have never experienced this "bog" that so many of you have described. I have
the Dale P/R unit on the 180 and it accelerates from idle just fine.

One thing, though, I never did get ANY improvement in gas mileage when I
installed the P/R pot.

Anyone have any idea why?
Thanks
