I have two problems :-(

As the title says, I have two very distinct issues.

The first is that with the bike level and on stands I am seeing fuel dripping from the drain hole in the carb if I give the bike a bit of a shake. I have checked that the drain screw has NOT cracked the float bowel. The float levels have been set to 14 mm when they are just touching the shutoff valve. from my point of view, the fuel coming out of the drain hole would indicate that the fuel level in the bowel is too high.

The second problem is with the compression pressure. after warming the bike up for around 10 mins, I carry out a compression test. With the throttle wide open and plugs removed and grounded, I crank the engine for about 10 revolutions and I'm getting a reading of 100 PSI, this is very low from the 150 PSI in the manual, has anyone got any suggestions as to what the issue might be?

Thanks for looking.
