    Truthfully, I don't think that compression is my problem. That's just one of the first things you check. So that's my idea behind it. I really feel like it's an air or fuel problem. February of last year...fuel pump, coil packs and fuel system all replaced and carbs were completely rebuilt. I've...

    Doing a compression test and something isn't right. When I have the throttle closed, or off just on the one cylinder, i'm testing right now.I'm getting 90. When I have the throttle wide open, i'm getting heading up towards two hundred!! That's definitely not right! What am I doing wrong??

    Question... How am I supposed to heat the engine up and to pull the spark plugs? Doesn't that make the spark plugs easier to break? I'm also going to check today to see if maybe my carbs are out of sync. I'll go ahead and check spark too.

    Had a little stutter at WOT and found a loose plug. Changed the plugs and made sure all were tight. Now motor is bogging down, struggling to get from 4500 to 5000 rpm's. Acts like it WANTS to go but takes a good minute or two of surging to get to 5000 and full speed. It was running fine except...
