G'day Troppo,
Sorry, don't have any info on those maxi-dwell you got on ebay....
don't you just make sure you have 1-4 lined up by a static method, then 2-3 are 180 degrees after... there is a little timing/neon light attached ??
Just give the carbs a good clean up, and make sure all passages are clear after cleaning them. do it twice to make sure (compressed air is really good for small blockages)..
most parts/jets should be ok..
the rubbers are not easily resurrected... I just got some decent hose clamps... and made sure the rubbers I used had no cracks in them....
