The pk xl is struggling to kick start when the engine is hot. I can bump it after running a few metres. It is fitted with new stator . Only had this problem a few weeks, Any suggestions where I should head first? Plug colour is bang on correct. When hot , pulling choke out or putting in makes no difference. I'm assuming carb issue, the cdi doubt been changed in years, I read this can play up when engine warm . Thanks all

CDI is a good starting point, easy to swap over and its always useful to have a spare if its not the issue.

Thanks guys. So being able to push start it gives a clue it's cdi? The scooter is 1987 electronic so that's a long old time if cdi never changed .

If it's flooding you will have an easier time to start after closing the fuel tap and kicking with throttle wide open for a bit. Flooding is a super common hot restart problem, usually means a float or float needle issue.

yes! compression check should be part of your diagnostics, and a pressure check of the engine is quite useful but a bit more work

Gonna try the cdi first as it's due for change. Got one on way. Then carb. The engines being split in august for crank, gear and barrel kit change so renew it all then . Power wise it flies and still hits 50mph as it's always done. Thx guys

Order a new float needle, too. It's super-cheap and easy to replace.

If the old needle is more than a few years old, it's probably not ethanol-safe and will fail, then leak and cause flooding pretty quickly.

The scoot is 35 years old and been driven in Barcelona heat since its manufacture. Thanks Chandlerman.
