Thanks for the information on the contact breaker point gaps. Concerning ignition timing. We agree with KenG's conclusions that a 2 degree advance was not enough, 20 works better. We are now wondering if there may be a misprint in some of the manuals. Thanks for the detailed write-up, appreciate the time you spent responding. LShort

BINGO, you were right .017 is the winner (per KBeach .022 - .025 for plug gaps) Thanks for your help. LShort

We found the breaker points gaps to be .017. It is a dual-ignition and the points are synchronized. Found the firing order on a plate on the valve cover, so thanks for your advice about another method for determining the firing-order - hadn't thought of that before. I'm currently reading "The Splendid Stutz" and read that in 1929 it's estimated 1,000 6-cylinder and 250 8-cylinder Blackhawks were sold. Thanks for taking the time to share info and suggestions, what a great forum for communication this is. LShort

KBeach (member) called and had a manual identifying the breaker points gaps to be .017 and we found this setting to work very well - resulting in increased horsepower. Original breaker points gaps were .025 and .032. As for ignition timing we agree the spark advance is more like 20 degrees vs 2 degrees. We learned, through trial and error(s), that greater timing advances did result in greater power output. The original timing was too delayed. Thanks for responding. LShort

What is the gap setting for a dual ignition, 6-cyl 1929 Stutz 2 passenger Blackhawk? Also, what is ignition timing? Spark plug gap? What is the spark plug firing order? Where could I find owner and technical manuals/info? Appreciate any assistance. Stutzgal
