no info on specs but you might turn the can CCW 2 turns with a 3/32 allen wrench (I'm assuming this is part throttle pinging climbing a hill, disregared if WOT), otherwise I would note your initial and your total and at what RPM it maxes out at & likely will need to first loosen/turn the housing to be able to see what springs are in there (OE combo is light/heavy with elongated loop on one end). Older (non Mallory) I am assuming.
