On my way back from town, the hobbit started to sputter. Meaning I could be WOT and it almost would sound like it was 4 stroking, then not even fire for a short period, maybe 1/4 second. Spuddered all the way back, barley maintained 25mph. Every once in a while it would get a second wind and wind out, then start to spudder again.
I noticed on the way to town, it seemed to 4 stroke down a hill.
