If the 86 is injected, possibly a blocked injector.

All other cases:
a) failed plug lead
b) cracked distributor cap
c) fouled plug. This occurs due to burned oil, common on old engines
d) broken ring, see c)
e) worn out valve stem seals, see c)
f) failed head gasket.
g) burned or leaking valve.

First thing, identify which plug is not firing, and have a look at it. If
its carboned up, you have oil burning. Check the leads and inside the
distributor cap. Clean of dust and dirt with WD40.

A failed head gasket may leave the plug wet. f) and g) will require the head
removed and reconned.

Sorry Stewart i failed to mention that i had sprayed carb cleaner in and
around the carb before my problem started, actually down the throat of the
carb and up thru several pipes coming from the air filter and the little
thingy on the firewall which hoses also come from the air filter. So i am
thinking, maybe i have moved a little bit of crap into the carb or loosened
dirt which is blocking some thing. The dizzy cover, leads and plugs are all
new

Help  lol
