Great job on your car, such a long time in getting it together, shows extreme perseverance on your part !

Try the insulator to see if it fixes the problem first, rather than pulling the intake off. You might also note that depending on the fuel, it may already be winter blend which will be awful for percolation issues.

Another way to overcome percolation is to install an electric fuel pump.

Good luck with it !
