I initially just shot a little starting fluid into the throttlebody, and it started after about 2 revolutions and ran just long enough to use up the starting fluid in the intake. Then I hooked up the wire to my fuel pump and took the 3/8" ID hose I bought from a marine supply house that has a squeeze type fuel bulb to provide initial fuel flow, and stuck that into a small 2 1/2 gallon plastic fuel can with added two-stroke oil. The engine immediately began firing, but would only keep running as long as the starter button was depressed. The throttlebody was in the closed position. Then, I noticed fuel dripping out of one of the intake holes in my TWM throttlebody. I opened the throttle a small amount, and the engine came to life immediately. Got the bejeebers scared out of me and shut it down quick. When I realized everything was fine, I started it again, a little less nervous this time, and without the white-knuckled grip on the fire extinguisher. Ran it for maybe 30 seconds and shut it off to inspect for oil , fuel and/or coolant leaks. I still had fuel leaking from just one of the two intake holes in the TWM throttlebody. I then disconnected and swapped the wires to the two injectors, and re-started. After this, the OTHER intake hole in the TWM throttlebody was leaking fuel. I think this eliminated the injector as the culprit. Possibly the wiring to one of the injector snap-on plugs is faulty? I should mention that I have a MicroTech ECU. The good news is that the engine started so easily. A little smoke at first from the WD-40 I had sprayed into the exhaust ports to keep the seals lubricated, but that cleared out after the first short run. Also good news is that so far, no oil or coolant leaks. However, I'm sure the thermostat did not have enought time to open, so I can't say there won't be any coolant leaks lurking in the woods somewhere. I was very pleased that the exhaust wasn't as loud as I had expected....It was inside the garage (read that as echo chamber), but sounded about as loud as a Lycoming. Of course I didn't run it very fast. Maybe 1500 to 2000 RPM's. For those who are not familiar with my exhaust, it is just the stock cast iron manifold with a short 10 inch straight pipe. I will have to try to figure out what to do next to determine why one throttlebody intake leaks fuel (after shut-down), and why it changes to the other hole when I switch injector leads. Gotta sleep on it. Fortunately, I will sleep well tonight, just knowing I can now make noise and scare my neighbors. Paul Conner, 13b powered SQ2000. yeah....really powered. Engine is no longer just an ornament.
