Son starting complaining that QT50 was getting hard to start and wouldn't restart after stopping. Wife said she noticed some smoke. I'd never changed crank seals on this one, so I did. First attempt after changing seals, it cranked perfectly, rode for about 5 minutes, it bogged and died. Watch the video. Spark is great, compression is fine, clear fuel line with good flow, spotless carb. What's the deal with this thing?
Bogging QT50
Bump. Could use some help.
Where's jack Rutherford when you need him ?
Kinda sounds like the CDI isn't being told to go from start to run on a 3 position ignition switch. So maybe bad connection somewhere or tired out CDI
I appreciate the thought, but does it matter that it's a 2 position switch? This is a 79 model.
Doesn't matter unless somebody put the wrong one in at some point.
Remove the muffler and it try again.
recheck your spark. in fact post a vid of your spark test
Tank not venting?
