I will try this again, ask earlier, but was kept hanging with no resolve. Have a 1971 Glastron completely rennovated with Mercruiser 165 inline 6, everything in her new except block and alternator. At first I thought I was vapor locking, put Phlenoic spacer on Rochester 2jet carb, but kept stalling after running for about 30 to 45 min, acting just like vapor lock. Boat will Idle but when you engage throttle will sputter and stall, but will start again, but will sputter and stall, takes about 20 mins floating around, then she will be ok. Has new gas tank, with new vent, and new gas line in her. After trying the spacer, heat wrap around fuel lines and more motor vents, I decided to crack open the gas cap to see if there was a venting problem, and this seem to cure the problem. Now I have put a new vent in with 5/8 vent hose, its not clogged, I have checked. Why would opening the gas cap and running with it open solve this problem? What do I need to do?
