if it does that might indicate too much carb if the flat spot move up in rpms
when it occurs.
I tend to agree with this one. If the carb is pushing too much air into the engine, it will crap out. One thing you can try is putting a very restrictive air cleaner (read that small) on the carb and then drive it. If the condition gets better, then you have found your problem.

That carb could just be pushing too much air for a mild 351W.
