1989 mercury laser 220 starts but won't stay running

[mr shag]

Hello, this is my first post so I'm gonna try to keep it short. I have a 1982 Glastron seafury with a merc laser 220 xri that ran great all last season. Due to no time I put her in the backyard since Oct. I started her up a few times just because and had no problems. Now when I'm ready to fish I tried to start her and she sputters out after a few minutes. My guess is something with the injectiors? It has old fuel in the tank so I ran it on a reserve tank with fresh gas and a Lil seafoam. It stayed running a Lil longer after that but still not good enough to consider towing down to the water. All suggestions are greatly appreciated Thanks

Drain tank, change filter on engine, drain VST tank and flush and see if it runs(not on water) if not pull the injectors and send to Brucatosvs.com and have clean,flowed and balanced. If you run it with stopped up injectors you can lean it out and cause damage and plus if dont have enough fuel it dont have enough oil.....
