With spring time temperatures making it a little more comfortable working outside, as of today, March 14, the Merc has ignition spark. It took a little filing of the ignition points (remember those?) and some cleaning of the distributor and coil terminals but now there is a good healthy looking spark when it cranks so that is one more step. With compression on at least 7 cylinders and spark on all , there is a chance the engine might eventually run. I did not shoot any video of this but here is some from earlier in the winter showing a brief compression test.
