Timing my old crossflow

I just got back in the house a few minutes ago, from being down at the boat dock timing it with a test wheel.<br />The wheel I borrowed had several numbers on it, 321210, 387388 and 135 stamped on it also. Accordant to Peetie-pie, (she was at the throttle,)our engine would only spin that wheel up to 4750 rpms. At any rate, setting the timing by my method and Joe Reeves method of 27 degrees did not work on my old war horse. It was 27 degrees up to about 3500 rpms but over that she would creep up to 30 degrees at 38-4000 rpms and about 32 at 4750. I made several clock-wise turns on the timer base stop to get it down to 28 degrees at 47.50.<br />It seems as soon as it reach over 45 the timing would just start increasing electronically. After finalizing it at 28 degrees for the number one plug. I tested the number two. It was only about 26 degrees. Is that normal? Remember this my time actually timing with a test wheel and timing light. I am going to buy or even make me some kind of test wheel for future test. I love to tinker. <br />OBTW, my engine is pure stock, # E 150 STL COH, J 057 8813, cylinder head #329772 PS, #329773 SB.<br />The only thing ever been replaced since new is the spark plugs, timer base, stator, both power packs, voltage regulator, OMS & oil tank, flame arrestor, recirc valves, re-glued all the magnets, cleaned and rebuilt the carbs, and replaced all hoses and fittings. I believe that is about every thing I done so far.<br />All work done was done to wake it up after a long sleep from 1988 until late fall of 2002. I would love to see an E-Tech top that long of a spell of not being winterize. :) <br /><br />Regards,DoferGofer & Peetie-pie

Hi, if the test wheel wasn't designed for your motor 4750 rpm's might be all you can get with it, at any rate those rpm's should be sufficient for timing purposes, all hooking the timing light to the number 2 plug would do is confuse the process,<br /><br />Sounds like you,ve replaced 'bout everthing that might need it, ought run like a champ.<br /><br />Mike :p

I will probably give a test run down the river tomorrow. It did sound good though. Hooking/checking the #2 cylinder is a recommended procedure in the manual for my engine.<br /><br />Regards,
