Re: WOT timing
both of the two previous posts tell how.<br /><br />for clarification and terminology, when I mentioned the neutral lockout, I meant when using the remore control lever. Of course, you do not need to do that. Use the throttle/ignition advance lever at the block itself.<br /><br />please read again carefully ...<br /><br />you are NOT ever running the engine at all during the test! <br /><br />The spark plugs are out and each one grounded. The test speed is while cranking, not running. With the engine thus "tricked" you are spinning by the starter motor at 250 or so rpm (plugs out) and with the ignition linkage artificially MECHANICALLY advanced, so it thinks it is "linkage" WOT, minus an "ELECTRONIC" 4 degrees <br /><br />Why? because when the electronics sense crank speed, a later timing is appropriate, so a default late timing of [mechanical advance minus an electronic 4 degrees] is automatically performed. So, for example, timing adjustment by this method for WOT on my motor is not for spec 19 degrees, but for 19-4=15. Yours will likely be different spec per your manual.<br /><br />Hope this helps.
