Massey Ferguson 35 has no spark, I have replaced the coil, what could be the problem?

Question edited for clarity.
Question moved from Gun Sight Optics.

1984. I think your serial number should be 702702, not 720702

I can't get the compreshion right on new sleeves, pistons and rings in my Massey Ferguson T20. I get about 35-60 when checking compreshion. I have taken them out twice and checked to make sure the rings are in correctly, etc. Your tips are greatly appreciated.

put a circuit tester on top of coil and turn the key to see if power is constants when key turned. If it cuts out then the key is wired up wrong somewhere. If that works, then check that power getting to distributor by leaving HT lead from coil attached to coil but unplugging from distributor. If no power there then the HT lead is stuffed. If that works, points should be checked. max gap should just fit a credit card width. Then condenser should be checked along with the HT leads to plugs and finally the plugs.

your breather is cloged and also check spark plug.
