My specific question is regarding the throttle body for my YF carb which has a cast 788 on it. The holes at the bottom of the throttle body which meet the insulator are approx 11 o'clock and 2 o'clock whereas most photos and the gaskets in rebuild kits put them at Appx 11 and 1 o'clock.
When I took the carb apart I noticed the gasket actually covered the hole at 2 oclock and there is no groove in the insulator to allow fuel out this hole and into the manifold. Should I make a custom gasket and use my dremmel tool to open this up or just slap on the gasket and cover this hole...
