Obviously the problem is that the color is all wrong - shouldn't it be French Blue

There is a nice one on eBay right now with your name on it...

I had a similar problem with my mothballed '71. After 20 years in storage, I was able to get it fired and idling in short order. But it had absolutely NO power. Rogerspeed picked off the issue: I had the firing order 1-3-2-4 instead of 1-3-4-2. Swapped wires and it ran like a top.
Regardless, I'm with John - you should do a complete SPICA tune up. It is so important to do every step in order. I heard Wes Ingram say that the motor actually runs worse as you step through the procedure until the final adjustment of the FCS and then it all comes together. That used to drive me nuts - I'd be half way done and it would be running like hell...
Also, as John mentioned, if the motor wasn't properly stored there is a big risk that the pump looses it's sealing ability. The real killer in this is that the fuel gets into the oil, lubricity goes out the window, followed by bushings, bearings and rings - not a pretty sight. So it is a good idea to carefully examine the oil for gas. I think I read that the simple way to do that is to draw some out oil and put a match to it. It there is fuel present it will readily ignite. If that is the case, don't run the motor. Send the pump to Wes.
Finally, I would be a little nervous if the PO just started it once a year. Just enough to promote condensation to collect... I think a properly pickled motor should be left alone (Certainly proved to be the case with my '71). Hopefully not the case for you but something to worry about if things are going too good so far...
Good luck and lets see some pics...
