I see your point Rev. Also I've seen posts by you and know that you know what you are doing. Sometimes I buy new parts in lieu of testing also. I should have said that in my "treatise". It IS a viable method for a DD if parts are cheap and easy to install and you don't live out in the woods.
Fuel delivery issues may the problem. Also condenser or coil or points (the spring not closing), new or not as others have mentioned. Jerry's flow test is how to test a pump. I prefer to see if it starts when HOT by putting gas down throat. I quickly know if it's gas delivery or not. Carry a little bottle of gas around your neck, when driving, for this purpose. Jerry's test is too messy and not safe.
I know all this stuff is hard to do out on the road. Try to catch it as you get home or leave it run in the driveway. You really need to pin it down to vacuum lock, fuel blockage/filter/pump or electrical/spark. As Carl says: seeing gas squirt from pumping throttle tells you if bowl is dry or not. Pouring small amount of gas down carb and it starts is good news.
Please let us know after you replace some parts.
