Re: 93 octane fuel
Shouldn't need that high an octane fuel unless you are running a high compression ratio. But to high an octane shouldn't cause a driving issue. How about bad fuel? I have seen several cases where the fuel (at the supple station) is contaminated with something, like diesel or water, etc.

Re: 93 octane fuel
The question, as asked, cannot be answered. Please define what "chugg" means? Running octane much higher than the requirements of the engine can cause some performance issues but I would not refer to that as being a "chugg".

Re: 93 octane fuel
The chugg description will need further clarification. At what rpm is this chug and is it when the engine is under load or no? Engines will miss and rpm fluctuations can happen under certain conditions but the only thing that chugs is a steam engine in my way of thinking. Stuck valves can cause after fire in the exhaust and a lean fuel mixture can cause backfire through the carburetor. These would be like the definition of "chug" when related to motor vehicles.

It doesn't have any more energy or higher performance. In a flathead it is a waste of money.

Re: 93 octane fuel
I run non ethanol fuel which only comes in 93 octane in my area, no problems in my ‘41 or the snow blower, lawnmower.
