Bubbling gurgling sound in engine after it warms up. Drained and flushed radiator and oil. Both normal no discoloration. Engine also cracks back at full throttle. Any suggestions or thoughts?

Sounds like the radiator is not holding pressure. Try replacing the radiator cap first.

It's holding good and snug, never had any problems with it. Doesn't leak or anything like that.

Richard Mallette “Engine also cracks back” could be a timing issue as well as a fuel delivery issue. The “Bubbling gurgling sound “ could be caused by air in the coolant system. You did not tell us if this all just started or if this has been going on for a while.

Just started yesterday
And is 49cc single cylinder
The coolant was kind of low when I dumped it and replaced it, but how do I purge it if air did get into the system?
