So the issue with my 2 stoke outboard is that i can pull start it just fine without the spark plugs in, as soon as i put the spark plugs in, i cant pull start it, as in i pull as hard as i can, and the thing moves a little but thats all. I checked the exhaust and its not blocked by anything. Does anyone know what could possibly be wrong with this? i looked at the manual and cant seem to find a solution or whats going on. please help, im planning on going on a boat trip/fishing Sunday with my father whose not going to be a round for much longer, please help!!!!
