Picked up something called a blow brush. An interchangeable brush head blow gun. I have yet to unwrap it and try it.

I also picked up a compression gauge kit before I realized that I already had one. This one is nice though as it has 12" adapter whips where, with the old one, the adapters screwed in to the spark plug hole, then you connected the short gauge whip. So, one set for home, the other for work.

Time to put the Suburban in the garage and see what is making the coconut banging sound on fire up. Usually goes away once warm.
