NO on the perry carb thing.
If you have a fuel pressure issue, it's not the carbs fault.
Try positioning the fuel tank correctly...ie: tank centerline level with the needle valve. A little (1/8" -1/4") above or below is OK.
This should be detailed in the engine instructions...again READ THE INSTRUCTIONS. The engine cannot be expected to run correctly if the tank is siphoning fuel into the carb, or...the engine is trying to pull fuel uphill.
Larry...put your checkbook away! You do NOT NOT NOT NOT NOT need a new carb.
