    Yup, I wanna know what the squish is and exactly what octane fuel you were using when it was backing plugs out. My guess is going to be poorly designed domes. I am assuming these are trinity domes, and that does not give me the warm fuzzies.

    There are many variations of viton. Yours is too soft I am guessing. 

  3. Are these off the shelf oring? As in are you guying at Zatkoff are someplace similar? Is it possible you need an oring of a different durometer? That is going to be my best guess is you need a harder oring. Also it is important if this is not a mono block to torque the head before torqueing the base gasket.

    That was some very good advice and knowledge you shared there brother. Thanks for the advice and I will definitely look more into this before I think about attempting this.

    Not so much on the good advice. He is overthinking the hell out of it. Do a little research on snowmobile fuel pump systems. All you need is a port in one of your intakes for the pulse, a fuel pump ( most any 2 cylinder snomo pump will work) and the proper needle/seat assemblies in your carbs. Its that simple.
