Guy's, anyone out there who can tell me what the proper dwell setting for this engine is? <br /><br />Also want to verify that I do or do not have a water seprerator on my engine. Someone mentioned this but I don't see anything else in the fuel line.<br /><br /><br />Thanks!

It should be around 30. That would be the dwell, not the gap. Trace your fuel pump back to the tank and look for a cartridge.
