A quick way to check for intake leak -while engine is running take a welder's
torch or a propane torch turn the acetylene gas or propane gas do not light,
run the nozzle around the carb connections and around the intake manifold
connections. If engine speed increase you have a leak.
Lack of power- check the pinch bolt on throttle pedal shaft to the linkage
first, then check the dash pots for movement up and down- they must be able to
raise and fall freely. Thirdly, check for timing advance weight in the
distributor- weights should move freely and correctly. You could also check
spark plugs- lean plug will have little carbon residue.
another area to check - air breather gaskets and air breather are not blocking
the carb vent holes where the breather attaches. Also check the vents to the
float bowls are not plugged. the carburetor requires atmospheric pressure to
move fuel through the carburetor.
