Anyone know if the pcv vac port on this carb will work or should i try to put a 90 on the air cleaner and let the carb pull vac for the pcv valves. This is on a 350
Not sure if that port on the carb pulls vac at WOT or not
so i need to pull it from the air cleaner or flame thing. I dont have the money at this time but i'll start to price one asap. I need this one to run till i get the other tho. Maybe i will run my blower at all time now when its running
Does your GM 350 have a pcv valve or only a dual vents? Most, especially Mercs, were only vents. Hooking one to the vacuum port on the carb, will be like a big vacuum leak, and make that car carb, which is jetted lean compared to a boat cal, even leaner.
The stock vent elbows look like pcv valves, but there is nothing in them. They don't pull any measureable vacuum connected to the flame arrester. It is just to draw in the blow by gases, mainly at idle.
If you do have real pcv valves, it is likely your 350 came from a car/truck.
