70 Johnson Starting issue

[Steele329]

Hi, I hope someone may be able to give me a little insight into a little problem I encountered yesterday. I launched my boat, started it up and found I had a very bad gas leak on one of my hoses. I pulled the boat immediately and went right to the store. I replaced the hose and went right back to the ramp. Problem cleared up and she ran great. Then after beaching up for a little while, she had a Huge problem starting. I choked it and primed it and got it going, and just brushed it off as I had been sitting too long and went on about my day. I stopped again and it happened again, only this time after a ten minute stop, engine still warm. I had to choke and prime it again, and yet again the next time I stopped. It runs fine once it starts, no issues or complaints. Prior to my gas leak this issue didn't exist, and I checked my connections and it looks good. The only thing I can think of is that its loosing its vacuum when I stop. Anyone have any thought? All help is appreciated thanks!
