Re: 90 pounds compression, good spark cleaned carb
Greetings:
What scooter?
I have a 300-mile top end kit for "sale" on fEeBaY. You'd be hard-pressed to find a cheaper solution. Compression was 144 last time I checked. Very low compression might start if it can get fuel, but there has to be enough vacuum to activate the auto-fuel valve if it's not sticking. 90 might not be enough to open the fuel flow to the carb if it is.

Most of my money is spent on scooterparts. The rest is just wasted.

90 psi is not serviceable. 144 is excellent compression. That's a 54# increase.

When you do a comp test make sure throttle is full open.
some people dream of speed, i own your dreams!
