I really like Perry carbs, especially when replacing a basic, non metered type of air bleed carb.

The original Perry Pumps were built into backplates for each specific make and model of engine. The instructions were very specific about having to use a Perry Pump Carburetor. I never had great luck with that combo and eventually returned to using suction for fuel feed and the stock carb. You can't use the Perry Pump Carburetor without the Perry Pump, or something else that boosts the pressure way up there.

To add insult to injury, what is probably a great product when properly handled and setup was ruined many times by the owner inadvertently using a petroleum based after run oil, which promptly destroyed the pump diaphragm.

If you need a pressurized fuel system, buy a YS, or other brand, pumped/regulated engine right from the start. You'll save money, airplanes and a whole lot of prayers begging for forgiveness at having lost it and cursed at the flying field. BTDT.

The Cline Pressure Regulator and the Iron Bay Pressure Regulators do work well, but both, the last time I heard, are out of production and can be difficult to find. Good luck.
