Hello, <br /><br />I had two questions about my newly acquired Honda 10hp 4 cycle. It says Honda 100 on the hood, and it has a dark blue bottom with a white hood. <br /><br />Anybody know what year it is? The model is B100-1002738 <br /><br />I was told that it was really a BF100-1002738, although it really says the first number on the block of the engine and on the leg. <br /><br />What would be good compression numbers for this engine?<br /><br />With those goofy little plug threads it has, because of those little plugs, my good compression tester won't screw in the plug holes. So I am reduced to using my old busted compression tester with the rubber nipple. I know it isn't getting a good reading, as they both only come up with 65 pounds. At least they are even, but I am thinking that 65 pounds is not really the case, as it seems to have more then that when you pull the cord.<br /><br />So I am currently trying to find some type of adapter for my screw in compression tester, to fit these oddball size threads. <br /><br />Anyways, just wondering what would be good compression numbers for this engine, and what might the year be. <br /><br />It didn't have spark when I first got it, but now that I have cleaned the points temporarily it does have spark. I thought that might help in identifying the year. <br />What years did they make these honda 100 10hp motors that were blue and white, and had points? Anybody know?<br /><br />Thanks<br />Mike
