The setting the initial idle by the transfer slot worked great .The engine idled at near 600 rpm.Problem even with new 3.5 pv's it loaded up and fouled the plugs on a ten minute drive.When I got it into the garage the front primary carb had gas fume clouds inside and appeared wet.I can check the diaphrams and they don't leak. The old original pv's leaked vacum , a slow vacum leak ,less than perfect. How can you check to see if the valve is actually sealing off the gas flow?
If it isn't the pv not sealing than I'm lost. I'm going to end up going to a pro.I'm not rich and allready have a load of parts.
