I am debating buying this 1985 RX7 with the 12a engine. It has been rebuilt around 8000 km ago, and has been street ported with a 45dcoe weber carb and some other upgrades. It has this squeal at higher rpms, is this something to be worried about or just a bad belt/pulley? I haven't seen the car in person yet so just have this video to go off of.
