Zenith 26 VF

I dont know if the Ford carb has a gasket or not but for carbs with the idle adj on the lid the lid should fit neatly to the top without significant gaps. Although usually shows as idle problems. A large compensator is usually more likely to assist than a smaller one. For a similar siamesed port 4 cyl engine, the jets relate more to the venturi size than any other factors so what works with the 8hp Ford is unlikley to be wildly wrong for others.
