Also, the more an engine gets carbon deposits, the compression will go up. There are two types of compression test. The dry test, which is where you just hook up the guage and measure, and the wet test, where you put a teaspoon of oil in each cylinder just before the test. If the compression is low on the dry test but is up on the wet test, then you have a ring problem. If it stays down, it is either a valve or something the oil is not reaching to. I heard a trick the other day on PBS Tv for getting rid of excess carbon in the cylinders without taking the head off. Get a windex bottle full of water and squirt it in the carb of a hot engine while at fast idle. Supposedly it will flake off the carbon. It usually will muck up the spark plugs, so they should be replaced/cleaned after doing this trick. mikey at trsvax 55, it's not just a good idea, it S*CKS!!
