RE: Falcon starting question, has anybody else gone through this?
Mark,
I built a propane adapter using a BernzOMatic torch head ($12.97 at Lowes with a tank).
I unscrewed the torch tip and chased the threads with a 1/8" NPT tap, I then had to drill out the orfice in the tip of the tourch. I then bought 1/8" NPT Tee and screwed it onto the torch head, I had a bunch of gauges from freon refill adapters (Advance Auto) and used a 1/8" NPT barbed adapter to interface with the hose.
The cool thing is if you keep the pressure in the blue zone on the gauge the engine will light off with no extra flames with the new larger orifice.

You might consider these if you want to utilize a Festo Tee coupler

or these with barb fittings if you want to insert directly into the hose

One note about using a regulator valve, the best pressure I was able to get out of mine on the high setting was about 12 psi., although my regulator was from a gas grill.

Follow up question... I build a similar setup using an auto tire air valve with festo fittings. When measuring with the regulated valve, I get 10-16 PSI. Good.
When using the benzomatic torch, I get one of two things: A) if the gauge is connected directly to the bottle, I can see the pressure slowly rising, matching how much I opened the valve. However I continues going up, no matter how little I opened the valve. This seems correct as eventually the pressure must match the one inside the propane valve. B) if connected thru a tee, no measurement at all. Of course the gas is escaping, but I was hoping to still get some measurement.
What am I doing wrong? How can one measure the pressure during startup?
Thanks

Hello Edgar,
You are correct, if you measure with just the gauge, like your first photo, the pressure will climb and equalize, no matter where the needle valve is set, your second photo will work to measure the pressure during the start sequence due to the fact that there is a gas flow with some back pressure,(i.e. in line orifice) therefore the needle valve will regulate the gas volume (pressure) as long as there is a flow.
