Lovely machine that had been attacked by an incompetent. Having trouble w/ cold start (long cranking + need starting fluid) + having to crank and use fluid for restart when warm. It has almost new "Ristance" spark and coil wires. Are these ok? Spark test just does not seem to be as big and hot as it should be. Have new engine temp sensor to install. Would bad sensor cause no-start? Good fuel pressure, new filter etc. Runs awesome once started.
