Thanks for the info. This is an 88' jug. I am familiar with a leak test, I do this on my turbo car occasionally but we call it a boost leak test. Could it be too rich with the jets that are in it? I just checked the plug and it looks blackened like it may be rich but then again the mechanic who put my  engine together told me to run the gas with a little extra oil while its being broken in. Would it break up on the top side if its too rich? I know my Raptor does this when its lean but not sure what happens when its too rich. Sorry for all the questions, again thanks for all the help from you guys. I'll do the leak test as well when I get a chance.
