WHY DOES NOT WORK

2004 MODEL 206 I have gasoline cylinder with SW tube.
after the vehicle has cooled down the engine
It works for 3-4 seconds with 3-5 starting force and stops again.
then it works again with 5-6 attempts. and this time it stops as it passes into the tube
It works after 3-5 attempts. (By the way, the starter prints flawlessly.)
No problem when the engine is hot.
After the cold, again trouble.

First of all, welcome to us. Sir, the probable problem seems to be related to the gas pump or relay. Of course, you need to solve this as follows. When was the vehicle last serviced? A racer 100-200 km in gasoline use of the same problems are in progress. In short, you need to fix your vehicle to run on gasoline. We even have the subject of a member who has a similar problem.
