How do i derestrict my lifan s-ray 50cc 4-stroke scooter please? forgot to add its a honda based engine and its a 59 plate thanks

Question edited heavily and to add maker.
Question moved from Cars and Trucks to model category.

This is a 4 stroke engine and gasoline doesn't freeze, only diesel goes syrupy. The most likely reason would have been condensation and damp causing the spark to short out. Another possibility might be old gasoline?

Engines only need three things to run

Fresh clean fuel.
A spark at the right time.
Compression

When was it last serviced, spark plug checked and gapped? Spray some WD40 on electrics.

to start with is it a 4 stroke or 2 stroke. If it is a 2 stroke the oil goes in with the petrol. If a 4 stroke look for a removable plug in the crankcase

It requires three main things to start the scooter:--- 1)Gas. 2) Spark. 3) Cylinder compression.---------- Any of the one is not functioning right so scooter is not starting.------------ Its possible that gas is not flowing till the carb and that is causing the problem.Either gas valve is clogged or faulty.Or gas line is clogged or carb itself is dirty and gunked up inside and needs to be cleaned.--------- Click this link below and follow the troubleshooting :--- http://whatisbyme.blogspot.com/2011/08/lifan-50cc-scooter-not-starting.html ----------- This will help.Thanks.Helpmech.
