Just acquired a Wombat 94 with no spark. Have NOT yet checked points. Would the rust around the ignition coil cause no spark or is it most likely the points. The bike has been sitting awhile.

Change them, points and condenser. I swapped out mine on Wombat and recently a Honda CT70 with success where there was no spark before.

Rust not likely to cause the issue, but of course clean it up (and clean the mount points for the coil and engine bolts)
Also, it would be good to do a quick check on that ignition coil - very simple, use a voltmeter - well described in the shop manual
Basically, connect a lead to the black wire and a lead to the blue - should read around 1.9 ohms. Then connect a lead to the black wire and a lead to the spark plug lead, should read around 4.6-5.7 ohms - if not, pull the spark cap off and check the bare spark wire itself - often the problem is corrosion or a disconnect in the cap/spark wire connection. All replacement parts can be bought at SH.

Ed, the rust would not cause the no spark problem. The ground is in the plug, but I would clean around the bolt holes so you have a good ground to the frame at that point.

Jack,

That was the other bullfrog who started this thread (one "l") - but the advice is good.

The two wire plug (black and blue wires) which lead to the coil provide (technically) all the ground needed for spark and good running. But, I too, like to have a clean/positive electrical connection at the coil core frame mount bolts.
