Honda PA50 II engine sounds

After a long-overdue carb cleaning, I was quite pleased to have the engine turn

over quite easily. But I am just a little concerned about the sound it's making...

I'm unfamiliar with what a properly tuned two-stroke should sound like (anyone have a reference audio recording they want to post?) , but I don't think 'putt putt _miss_ putt putt _miss_ ' is the correct sound an idling engine should make, and 'vroom vroom _putt_ vroom vroom _putt_' is right at high RPMs.

Now, it could just be due to splash fouling - I did a plug chop after running the engine slightly above idle for 5 minutes or so, and the plug was definitely splash fouled - and if so that should go away after a good long ride and a new plug, right?

Any pointers on how a moped engine should sound when properly tuned up?

Especially what idle should sound like.

PS: Easiest way to get to the carb is the "remove the hanger bolt and drop the engine on a block of wood" technique. The hardest way is to follow the machine shop manual and do a full separation of the front and back halves. Guess which one I tried first...

PPS: I discovered the hard way that the carb can be reassembled in two ways, one of which (reversed lower cover) leads to the float valve being stuck up and fuel spilling out the overflow. Of course, I found this out _after_ having put the engine hanger bolt back in...
