No issue when running slow or fast. Just started doing it today. Ideas?

Fuel pump maybe not pulling well at low rpm.

you give too much info about your engine and end up getting weird answers lol
clean the spark plugs clean carb or throttle body . mix fresh gas from shell or exxon with your old gas. cold weather is hell on idle speed.

Rglide is probably on top of this, could also be stuckopen thermostats and engine is too cold and spitting back thru carbs . Fuel pumps diaphragms are pretty common also

 

[Ronnie Redwing]

Has one of your buddies adjusted the lo speed needles for you? May have then too lean

What was it in the shop for?

 

[pick44]

overheat buzzer. one side was clogged with stuff and they cleaned it and acid washed it and put in new seal on that side.

 

[pick44]

since they did that, the motor has a deeper sound. almost like a car without a muffler

 

[Ronnie Redwing]

Did they have the gearcase removed during cleanup? May have left the exhaust tube seals out

 

[pick44]

I will ask them about exhaust seals. Thanks

Engine was pop and die on idle while not in gear. Today, it did same when in gear at 1,000 rpms

a pop or puff sound, like missing. So it is progressing from only doing it in idle and not in gear to being in gear at 1000 rpms. When I run it, it runs great.

Nechanic has not responded. Probably closed for the new years.
