*** Moderators Note: Thanks to Oldbull8 for the write up. While not a tech article per sey, with the limited equipment available to do pulse method timing the "official way", this timing light method will most likely be the one that endures. Every IDI owner should have this equipment and know how to use it. - Mel *** Finally got around today to try out my new Ferret timing adapter. I did not change the timing. Just checking the timing on an 88 engine that was supposedly had only 75K miles on it, since running it for an hour+ , found the front and rear seals leaking. With the damper timing mark wandering could that indicate a weak IP or the injector itself? Tools needed. Digital timing light, Ferret adapter and wrench for IP nuts. Six pack of 16 Oz Bud. 1st Pic-- Wrench is a modified 9/16" bent and end ground down, digital timing light and Ferret. 2nd Pic-- Clean off #1 cyl. fuel line. 3rd Pic-- Ferret adapter mounted and Grd. wire attached. 4th Pic-- Timing marks on the damper and timing plate 0 degree mark. 5th Pic-- Factory marks on the IP and mounting flange. IP was advanced to pass side about 1/16". Engine has a knock when idling, but smooths out at about 1000 RPM. 6th Pic-- Idling RPM. 7th Pic-- Advance degree setting. 8th Pic-- 2080 RPM to check advanced degree. At that RPM the damper line goes all over the place, but most flashes bring the timing to the 0 mark, so I assume that the timing is advanced to 8.5 degrees. 9th Pic-- Ferret adapter mounted. I have no idea what that fitting is below the adapter, the hat shaped thing is plastic and slides up & down about 1/8".
