K341 AQS question

[Darn Coyote]

Can anyone tell me what the letter "Q" stands for in the AQS designation? I think the "A" means modified oil pan,
and the "S" means electric start, but I'd like to know what the "Q" designates. Thanks for any help.

Q stands for quiet. Basically it means it is a shrouded engine.

Great! Thanks for the information.
