ACS Products A-790-20-0480. Length from panel to end of outer sheath is 48" - can be shortened. Solid wire end. Requires a cable end "b" nut (P/N 222-2 or similar) to connect to mixture lever on carb. Bought new last year, never used. This cable is NOT PMA, so good for experimental. Maybe OK for a field approval, but that's up to you, your IA, and FSDO.

Spruce sells these for $82.75 + tax & shipping. Asking $40 including shipping to the lower 48. PayPal & checks OK.
