I have dellorto 40s on my engine and they leak if I don't flip the pit cock. Over time I notice that my oil will smell like gas and my engine will stutter under load. My question is, are my carbs the only problem i have, or does fuel in the oil mean bigger problems? Also, how bad will the fuel in the oil screw up the lubrication of the motor and how quick could my rings go bad. Thank you for any replies that could help.
