Thread: carb spacer

    carb spacer

    Hello all. Am putting the 263 back together and have come across a dillema. I ordered a new carb spacer and the one that I recieved was one half inch thick. Seems larger than the one that I remember taking off. Does anyone know if this is correct. How much of a crush factor is involved? The spacer is made up of what appears to be seven layers, and the old one seemed more like four layers. Can I peel some off? Also do I still need to use the gasket I recieved with my rebuild kit along with the carb spacer? I know, very needy right? Thanks in advance, Doug.

    Carb spacer

    If you have room under the hood for the extra height, use as is. The spacer acts as a heat sink, and keeps the gas a little cooler. If too high,
    certainly take off the ones that make it too tall. I think they would just peel off.

    Straight Eight is correct.Thicker is better.The more you can insulate the carb from the heat of the exhaust manifold the better.I've heard of guys making them out of 1/4" hardwood like maple.Wood is a poor conductor of heat so it helps keep the carbs a little cooler

    Yes, thicker is better. I replaced the ugly and flimsy 5 or 6 layer spacer/gasket by an 1/2 inch thick, milled from a block of good old bakelite. This stuff is resistant to heat, gas, oil and most other solvents and is a very bad heat conductor. Went as thick as I could go without having to change the intake-to-carb studs. On my '48 248, I had to put an extra washer under the intake silencer pan, so that it was not meeting the carb at an angle. That was all. In case you use the original 263 silencer, check that the fastener on the valve cover has some adjustment range to provide for a variation in spacer thickness. Otherwise the silence might not sit tight on the carb.

    Good luck
