You're saying it stumbles when you let off the throttle? In neutral, deccel in gear, what rpm etc.

not a problem in neutral, haven't really checked the rpms when this is happening, all this started when I took it in for a tune-up a couple of weeks ago.

So what, when you're cruising normally and just let off the gas?
Does it idle rich?

Yes, it does it when I cruise, took it back to the shop and they are going to check the
carb on Monday.

It could just be a slightly rich idle and/or no dashpot.
