CHRIS CRAFT COMMANDER FORUM ® .......A photo-intensive technical reference file and ongoing newsletter regarding the original fiberglass Chris-Craft Commander series. This is an independent not-for-profit and non-commercial web site, not affiliated with the Chris Craft Commander Club ~~ or ~~ Chris-Craft Corporation. Our mission here is to "have fun and share information" about the Commander series (and those associated fiberglass boats on the Chris-Craft family tree) for your individual personal use, and by doing so help promote the good name of Chris-Craft, and help preserve, restore, and appreciate Chris-Craft boats. The main reference feature is the ever expanding MASTER INDEX File which contains what we believe to be the world's largest collection of documentation photos and technical information on the Chris-Craft Commander line of boats, (like these original brochure scans, featuring the iconic first 38 Commander styled by Fred Hudson, and many of the great Dick Avery renditions that followed) , (a huge collection of Chris-Craft 427 tuning and specification information), and a few words about how to use the forum.

We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common ! Just start by posting a note introducing yourself to the group, that's all it takes here (we don't ask for or retain any personal information here, because our intention is to just "have fun and share information".

Response to Re: Opposite rotation

I guess one thing I would do is to watch the distributor advance by watching the movement on the timing light, and then revving the motor to the point where the advance is "all in". That is normally, as you stated, in the 25 to 30 degree mark. Then I would back up about 30-degrees to the point where it should be TDC, and then move to a point where you are around 10-degrees before that mark. That, in the absence of good markings to time to on the graduated scale or dimple, should put you right about the same point you would normally be if you did get the proper reading on the dimple, while at idle.

If that is the same general location as the dimple, then you know you at least have a baseline to work with. From there, if that is not working, I think I would run some in-the-water tests and tune by ear. I'm not sure if the motor is actually running and the cam is activating the valves as it should, that you really have anything to gain by pulling the front timing cover, but I can assure you it would be A WHOLE LOT EASIER TO DO WITH THE MOTOR OUT OF THE BOAT. I made the mistake of installing before I checked for oil leaks and had to wrestle with a nasty little issue for weeks thereafter.

I posted your dilemma on another source of information and we'll see if anyone can give us some pointers. Stay tuned.

best,
Paul
