What is the valve on top front side of the engine (circled) and should there be air pressure in it? Also should the red plastic piece (also circled) be pointed in any particular direction? Picture attached. Any help is appreciated thanks!

That is the wonderful electric primer valve.-----Takes the place of choke flappers.------You push the key in and hold it in during cranking for cold starting.-----The shreader valve allows you to inject storage oil or engine tuner products.-----The red lever allow you to manually open the valve should you have a dead battery.----Yes this motor will start / run with a dead battery.----The picture shows the red lever in the proper RUN position.-----Get an owners manual before starting this motor.----Determine if oil injection is in service or bypassed.-----Replace impeller if this motor is new to you.-----Test overheat horn.----Do a compression test post the numbers here and keep them for the future reference.-----This enough to confuse you for now

Oil injection is by passed as I have to add oil to the gas when filling up.
What/ where is the impeller & overheat horn located?
