1909 Regal backfiring Issue.

Recently Thomas and Joyce Edfors had to hop over to a steaming Stanley after their 1909 Regal Tourer started producing hick-ups. It is one of those nasty little problems one can run into when touring an old car. We give the word to Thomas: "The problem with the car mystifies me and many others on our tours. It starts when we are either doing a steep grade, a long uphill but slight slope and/or a long straight road on a warm day (at about 30-35 MPH). Everything is fine but suddenly it makes a 'gurgling' sound, backfires (actually a series of backfires), power is lost and finally it typically blows water out of the radiator but always shuts down. If one waits for a few moments, or takes the time to add a little water, it starts up again and we can drive away. What is also strange is that after this first episode it may not do it again for the rest of the tour or, it will do it again in the next few minutes, five minutes or an hour later but sometime down the road it starts doing it again it will do so over and over. I have only one thought so far about this. There is a heat tube that fits to the exhaust pipe and connects to the air intake on the carburetor. While this heated intake air may have been needed when the car was new, due to poor gasoline at that time, I fear it is now boiling the gas in the carburetor when it is under such a load and causing vapor lock and fuel starvation. Having a thermo-syphon cooling system, this would appear to also cause the engine to overheat to the point that the some of the water turns to steam and it blows water out of the radiator overflow. I think I should remove this heat tube. Also, there is an in-line fuel filter which also could be helping starve the carburetor when gas is needed under load. This is a gravity feed system, as was typical in 1909. This may also need to be removed. "

We are eager to hear from you. Can you give Thomas some advise?
