Baja 5T 3 weeks old pullstarter hard to pull

[motoadve]

Its hard to pull after the initail phase then doent pull out all the way.
I checked the mechanism of the starter and is clean and smooth.

Is more related to the flywheel?

Engine starts and runs good.
The feeling I get is maybe too much compresion, like if there is too much fuel.
So I took the spark plug out, pulled a few times to take out amy excess fuel , put the spark plug back and it was the same.

Clutch is free too

A friend told me to open up the gap clearence between the flywheel and the magnetos, what do you guys think?

When you removed the plug, did you turn the rig upside down to expel the excess fuel while pulling the pull start?
