The timing may be retarded a couple degrees, If there is no spark knock or afterrun you could advance the timing,I was unable to get the HES timed using the "audible Method" as I mentioned earlier. I searched and found a method using a volt meter. Set flywheel at TDC, locked in place, connect voltmeter to ground and orange wire from HES to positive(red) lead on voltmeter. Rotate HES plate fully clockwise. Voltage should be 0. Rotate HES plate counter clockwise until meter pops high. My volt meter was showing in the 12V range at this time. The position of the HES plate was very close to the position of the original HES. The only problem I had was when I secured the HES plate and rotated the flywheel 360 degrees the volt meter spiked a little before TDC. I repeated the procedure three times with the same results. I have test driven it at this setting for about sixty miles and it seems to run ok. The only issue seems to be a problem at idle. When cold it idles down and dies almost immediately. After it has warmed up to operating temp it idles very slowly, probably 750RPM.
