Back again... Can't get engine to fire up??? Changed out plugs, new impeller and oil. Since service got engine to fire up and run like a champ, 3 days later went to adjust carb needles for proper adjustments and can't get engine to start. I'm down to a couple of troubleshooting options that I need help with. Does the plugs come properly gapped? Should I clean the carb? And last how do I know if I'm flooding it? Engine kinda fired but I wasn't quick enough on the throttle to get her going. One more thing is can the prop nut be too tight for engine to fire up?
I know it's a lot of questions but I'm lost? I've had this engine purr in a trash can over the last couple days but now I'm gettin nothin .....

Did you replace the coils, points, condensers, wites and. Boots?
The carb should be pulled. Get a carb kit and give the carb a good cleaning. Motor should be a one pull motor after that.
