Re: Souped-up flathead problem solved
Robert, I had the exact problem with the paper filter elements on my dual carb set-up. It took me many hours of frustration trying to figure out why the engine was running so poorly....didn't dawn on me that the new filter elements were restricting air flow. Each time I tweaked something with the carbs, e.g., power valves, jets, etc, I replaced the filters before starting the engine. Luckily, one time I left them off, and the engine came to life. I forget where I purchased the filter elements....no doubt they were an off-shore product. Lesson learned. I don't use any filter elements now. Just the louvered style of "air cleaner." I figure the limited amount of driving I do does not pose a problem running without filters. Richard
