I just can't get my 3W50 primed. Even after 70 or 80 flips there's still no fuel in the carb. To get my engine started (only for the first flight of the day) I have to remove my spinner, prop and cowl. Than I eject some fuel direct into the carb. After that the engine starts good. After it has run for a few moments I stop the engine to install cowl, prop and spinner. (A lot of work eachtime). For the rest of the day the engine can be started. Does anybody has any idea what I'm doing wrong. To prime the engine I close the choke, throttle all the way open and flip the prop. Please let me know how you prime your engine.
