At 15 Tanks your broken in. Hopefully it's still hard to turn over. Meaning with your hand trying to turn it over by the flywheel is difficult to impossible. A RB reaches it true break in after a gallon. This coincides with there long life characteristics. A RB #6 which is a med plug. Is a good all around plug for that engine. Keep temps between 220-250 and your good. Some run them hotter I wouldn't. 220-250 makes plenty of power.

some people still get this mixed up. when the plug is out and you turn it over and it gets stuck at TDC that is Pinch. when the plug is tight and you turn it over that is the compression. so to not start an argument as told to me by Rody of RB, when the metal Pinch at TDC is gone than the breakin is complete, it takes some longer than others so dont rush it. after the pinch is gone with the plug tight you should have a lot of compression. i used to ask the same thing, but even when the pinch is gone it still takes a little more fuel for them to be just right and most it is at the gallon mark.

right, it should have descent performance for the first gallon then after that all of a sudden its like woa! yeah!!. pinch and compression are different, metal pinch should be gone but compression should be around for a long while. i always ran the odonnell 99 plugs, bought one with every new gallon and never had an issue in over 4 gallons.
