Game on then 
How do you tell it it is a Harmonic type - or do you mean they used the same one on all engines?

Harmonic ones have the rubber insert.
I think the early ones and small bore ones have a all steel pulley with no rubber damping...

nar - to do with odd harmonics that the big bore engines generate.
i know that bearings seem to fail quicker when not running the damper-pulley on 1275s...

The damper's there to absorb the twisting vibrations of the crank when it turns at around its natural frequency. A 998 pulley will get you mobile but I'd still keep looking for a damper one.

That is the plan.
Need to get it all together - then whip the one of the engine thats in it atm

Wilson, I'm sure you know I've been looking for a damper pulley for a while too and found on eBay the other day that had the title mispelt.
It was listed as a 'pully', might want to search for that as well as pulley/puley? People spell things wrong and they don't come up when you search spelling things right.
Hope you find one soon!
