My fuel tank builds up a lot of pressure (I've read most of the "swoosh" posts). I've tried disconnecting the vapor line from the tank (firewall) to the charcoal cansiter and the tank remains pressurized until I open the gas filler cap. Is that correct? I'm wondering if the two-way valve on the tank is not functioning properly, I've read the test proceedure in the manual for the two-way valve which doesn't make sense yet, it would be helpful to know how it is supposed to work.
The main problem I am having is a hard re-starting (10-20 min) in warm weather. Once it starts there's a small amount of smoke and the rpms are very low an it runs rough for 45 seconds or so then it runs great (choke operation ok). I removed the line from the secondary fuel filter while there was pressure in the tank and fuel squirted out with considerable pressure until I opened the gas cap and relieved the pressure then fuel siphoned back with considerable vacuum. I'm thinking the pressure from the fuel tank is overcoming the float valve and flooding the intake manifold (?)
Any thoughts or suggestions would be much appreciated.
