Conquest Timing Marks

Post by Bonzodog »

The ignition timing marks on the DJ Range (Conquest) are on the rim of the fluid flywheel where, especially under the effects of fifty odd years of grime and corrosion, they are practically invisible. Can anyone suggest a method for accurately determining TDC and the timing mark of 9 degrees BTDC?

Richard,

Never used a timing mark in all the time I have been involved with cars, both modern and classic.

Slacken off the dizzy.

Get the engine running and set to a fast idle with the hand throttle

Swivel the dizzy to a point where the engine runs fastest. (check on Tacho, or by ear)

Get in, put in top and depress throttle. If it doesn't pink, job done. If it does, notch dizzy back a couple of degrees and get to the most advanced point where it doesn't pink.

Tighten dizzy.

I agree that the timing marks are difficult to see through the small aperture even if they're not rusty! However several of the bolts on the fluid flywheel casing are visible. Perhaps someone with an engine out could verify the distance from a bolt to the timing marks and we could then time to the bolt (after making said adjustment)?
