Re: dl-50 tuneing
Sounds like you could be a little rich on the low end. Any burble should clear up by 1/3 throttle if the carb is properly adjusted. Are you running the engine with the "factory" needle settings?

Re: dl-50 tuneing
Sounds like you need to vent the diaphram on the carb into the fuse.

Re: dl-50 tuneing
Here is a good thread that will explain how to do it. It is more prone to happen on round cowls with all of the open air up front.
