Unit starts on first turn of the ignition switch once unit is warm. If unit sits outside 3-4 hrs, or inside overnight, it takes about 20-30 seconds for the engine to catch. It has an Asian electric regulator which I rebuilt over the summer. Both solnoids on the regulator were replaced, as were all the gaskets/diaphrams inside the unit. Engine is equiped with the ECS system & the serial number is 65353. Any help would be appreciated- Thanks.
