Re: Odd Dyno results

Is that bung through a "wet" part of the exhaust? I can't really tell from the inside pic.
I just got to studying the picture of my manifold (above) and there may be enough room on the riser, just...

Re: Odd Dyno results

Thanks Doug,
That is a good read.

Re: Odd Dyno results

Float levels are good, idle transfer slots are "square".

Put my motor back on the dyno today, mainly to check Air/fuel ratio and to test some carb spacers.
