Dick....
Get out the manual and do a major tune-up. This will get you started on the
right
foot to begin with.
On emissions removal......how far have you
gone in this respect and how far do you plan to go?
Engine crankcase intake air comes from the
charcoal cannister into which the fuel (tank)
system vents (closed loop system). This air
enters the crankcase via the valve cover
takeoff, which has a specifically sized hole
("graduated orifice") in it's tip.
Since you've removed this "feed" according
to your post, "clip" the end off this valve
cover "takeoff" as it is now acting as a (1/2")
crankcase "vent". Attach a rubber hose
to same and run the hose vertically down
the side of the motor clear of the road
surface by a couple of inches. No need to
cap this hose with a filter, as even though
the crankcase will breath through this hose both ways, there is sufficient
vertical travel to prevent ingestion of foreign matter.
Have you removed the feed to the carbs
from the flame arrestor/oil separator mounted on the timing case cover as well?
And the air pump with it's manifold injecting air into the exhaust ports??
Since the engine is no longer "pulling" air/vapors from the fuel (tank) system
via
the charcoal cannister, replace your non-
vented fuel cap with the older, vented type.
As otherwise, the circumstance exists wherein the engine will die under heavy
load (acceleration) due to possible fuel
starvation caused by a vacuum within
the fuel (tank) system. The "vented" cap
will prevent this possibility.
