So I swapped the carb on my p200 recently to have the stock 2424 on it, definitely no issues with fuel, jetting, gunk etc.
Ride for approx 15 minutes then park it not running for five. Will not fire back up unless it sits for about half an hour or so. I took the plug out and noticed it is kinda oily and also noticed a small amount of oil coming 'up' from the exhaust flange towards the cylinder when running. See video below on that. Could this be too much blowby fouling the plug with oil due to wrong sizes ring gap or possibly oil pump sending too much?
