Postby sim » Tue Aug 24, 2010 11:11 pm

Hi,I've recently bought a wd8,got the parts I need to finish it but need a diagram of the timing marks etc.I am getting the new book by Dave Edgington but am a bit impatient!!!
If someone could mail me this info or post it on this site in the meantime I would be very grateful!
Thanx,Si m

Send me your email address via PM and i will send you the page with the marks on it.

I hate to burst your bubble, there are no pictures of timing marks in the NEW book!!

I also have acquired a Wolseley lately, the designation on the engine plates read WD9 but it is very rude bolted underneath the nuts of the crankcase plate it more resembles a WD8 if I compare the pictures.
it must be a late production the oil dip stick nut is plastic ( white) as is the gear the magneto is driven by.

some one must have put this gear in teh wrong postion and I try to locate any timing marks, therefore I joined this forum and put my post where I think it is relevant.

by the way I am a moderator of the dutch solex forum and the members nick named me solexdoctor reason to register me here as such.
recently retired ( used to do failure analysis as a job) and started to collect vintage stationary engines, one of which a Wolseley "eierkoker" ( Dutch) a "must have" for a collector

I solved my problem, made a marker by bolting a stainless spoke underneath one of the crankcase cover plate nuts.
removed the head and put a white line (T for top dead centre) on the flywheel at the marker.
subsequently rotated the flywheel until the magneto "clicked" ( Sparks there at zero revolutions) als a mark "M" for magneto
way too much retarded, the compression needed to ignite already gone.
By advancing the magneto ( change the gear tooth by tooth in the direction of running) I did bring the "M" closer to the "T" but making sure there still is timing AFTER top dead centre to avoid at all cost a backfire which would crush my wristst when applying the starter handle.
Yes a RUNNER, which allowed me to use a timing light and check the ignition timing while running.
Not Too much of an advance so I gave it anoter go at the gear, another tooth shifted. I could do an extra one since there is stil ignition after TDC,
but for the time being I am satisfied the running timing now is "F" for firing some 6 centimeters on the perimeter of the flywhelle before TDC

Make sure if the slotted plate comes loose to mount it correct BOTH side have the groove a little bit off set ande the grooves are at 90 degrees to ech other to act as a "universal joint" compensating any machining misalignments
