all right ..
that's progress ...getting the goal to get da tools.
a half-decent screw-in compression tester at Harbor Freight can be had
for 20 bucks or so I imagine.
while there, look for an insulated spark-plug wire pulling pliers ...
so you can pull off one plug wire at a time while it's idling.
heck ..you GOTTA have an IR Temp gun ..
cheap ones might be $ 30 ..
REALLY a super valuable tool.
Heck ..with it idling warmed up ...
just shoot the temps of each exhaust header pipe ..
that'll tell ya in 10 seconds which cylinders are producing power and
which one or ones are not.
Don't even have to take anything apart for this basic and valuable test.
