I cleaned and tuned an '03 Viking that I recently bought for a friend. The internals were very drenched in oil. I'm surprised that the solenoid was ok.
After having a hard time looking for my pressure test adapter and gauges(found scattered all over the house) to get the viking dialed in. I decided to set my pressure test kit in a foam lined case. Still need to cut the foam for the adapter sections but waiting until I get a few more pieces.
