[QUOTE="BJ1, post: 583029, member: 355"] The big problem with single 34 PICT 3 carb on a large engine is the idle circuit. You can indeed increase venturi size and rejet the carb but you are still left with the problem that the idle ports (tiny holes drilled in the body next to the butterfly) are too small for an engine over 1641. So to get the engine ticking over properly is not easy without enlarging these ports. If you don't do this then the mixture has to be overrich to get the engine to idle, which means its too rich for the engine overall. I remember people in the States using these carbs on buggies and sandrails with big engines, by enlarging the idle ports with fine drills, but I've no idea what size they used. [/QUOTE]
