How to test under load (dum question)

[spareparts]

other than using a prop shaft dyno, there isn't a way to load the engine. Check the accelerator pump function, with the engine off, have omeone pump the throttle while you're looking down the carb throat, you should see two streams of gas squirting into the throat everytime you pump the throttle, if it doesn't then theres something wrong with the carb. Check your timing, you probably have the automotive distributor based on all teh other auto accesories on your engine. Using a timing light, set the initial timing to 8 btdc, rev the engine on the hose and make sure the timing advances, the mark will move while being observed with the light on
