That gaskets is thin, not sure of the actual thickness but I always use the real tecumseh part when it comes to the gaskets, I never was good at making one.
Some of the knock off gaskets are three times as thick as stock and that will effect the throttle buttterfly rods interaction with the timing advance cam (moves the carb out and away from the cam). I'm not saying a thick gaskest can't be used but to get the engine tuned to run its best you will need to pull the flywheel and go thru the sync procces per the manual or slightly bend the plate that the brass butterfly rod sets on up a little will work to, also on the thick carb gaskets you get some erosion around the fuel pump pulse hole , thats my experiance with them.
