Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical faults. Thorough inspection of grounds and connections is essential.
Carburetor Tuning:
Weber/Dell'Orto carburetors require periodic adjustment and maintenance to ensure smooth running and optimal performance.
Transaxle Clunk:
The transaxle layout can sometimes exhibit a 'clunk' when shifting into gear, often related to wear in the driveshaft U-joints or differential mounts.
