I used part of the intake, most of the exhaust manifold, stock crank angle sensor, the ignition coils with the stock plugs and the stock fuel injectors. All Tracy's electronics also. My engine starts within 2 blades rotation every time. My procedure: Turn on fuel pump or pumps, crack throttle a small amount, hit the prime button 3 to 5 times - hear the injectors fire each time, adjust mixture full rich - press start button for starter. If engine temp. is 50 or below I turn the cold start switch on and off as necessary to keep it running during the first 30 seconds of warm-up. If hot - I try to start without any prime. If necessary I will use one or 2 prime shots when hot. I suspect you are not firing the plugs when trying to start the engine. I'd remove one plug from each rotor - attach each removed plug wire to an ignition tester - neon light in line (from Harbor Freight $1.99 sometimes), place the plug against the engine, leave the fuel pumps off and turn the injectors off. Crank the engine in the regular fashion. You should see each rotor plug wire firing the neon light and a spark across the plug gap. One more thing to check before you run it - I had no water being circulated in the cooling system at first. The water pump had an air bubble trapped in it. The only reliable way I found to get it out was to add a radiator drain valve at the top of the thermostat housing. Open it when filling coolant and leave it open until coolant flows out! Hope you get it figured out soon!! Dennis Haverlah RV-7A, Renesis, James Cowl --------------050402090507040308070903 Content-Type: text/html; charset=us-ascii Content-Transfer-Encoding: 7bit Don,
