thanks for the tip
my muffler tip was bent, I opened it up, but alas, no noticeable difference.
Earlier today I made an attempt to remove / clean my carburetor. Man, that was a bitch.
I got the engine separated from the frame, only to find out that my screwdriver can't get a grip on the semi-stripped screw heads on the intake manifold. I decided it was time to just leave good enough alone.
Maybe another day I'm feeling more ambitious and have a screwdriver with a larger head, my carb will get clean.
Of course, I'll also need to take my carb out if someday I upgrade my exhaust.
That techno circuit looks like It would be great adapted to a hobbit.
