And if you don't mind, how do you run the test? I am sure tester comes with instructions, but I'd like to hear how you do it. Thanks.

I remove the hose that goes from the carb to the fuel pump preferably at the FP end and attach a length of hose to the FP outlet. You may need a nipple to connect the hose with. With that set up, place the other end of the hose in at least a 16 oz container. Start and idle the engine for 1 minute or until the container is full. specs are:
minimum volume: 1 pint in 20-30 seconds.
Pressure: 4-6 psi

I've come to the conclusion it is a dirty carb. Took carb off and started the rebuild process. Probably need to replace the tank as well, since it must be the source of the debris.

Carb cleaned, reinstalled and runs well. Having an issue with choke linkage though. Does anyone have a good picture of what it should look like or know a site with good pics?
