Backfire turned bad day

His shot isn't all torn to hell, but wasn't the original question why it wasn't starting and just popping through exhaust? Pretty easy to suggest a compression test. Bout the first thing ANYONE would do! Still dont explain why it doesn't start though does it? All these engines you build and all the stuff you do, how do you have time to be on here running your mouth about how stupid every one else is on EVERY SINGLE thread and how no one else's stuff is worth a shot and you know EVERYTHING? Seems pretty childish and arrogant to a bunch of guys just looking to share ideas and info!
