Ok here goes, I've got a 1975 Johnson 115 that last year ran great, Tried to crank it this year and it will crank and then go right back died. Took to the shop because I don't know anything about rebuilding carbs and had them totally rebuilt but still having the same issue. Shop told me that the power pack was bad, Had a old spare off another boat changed it out with that one and still the same issue. What's the chances of the spare one being bad? I've had it for quit a few years after I swaped heads out because of a ring broke on it but I figured that one was good. I'm thinking it may be a bad fuel pump that's causing it not to crank but not sure. Don't want to be spending $60 on fuel pump then still have to spend $130 on A power pack. Comprition is good at 110,113,115,110 accross the board. Thanks in advance for the help
