55 mph & low comp? 1997 spx

[imron13]

First I want to thank everyone with the answers to the problems I have had.
Changing the (grey) fuel lines and cleaning the carbs made all the difference in the world. Went from hardly running to a touch of the start button and a legit 55mph with hand held gps.
I did check comp (cold) and have 100 on both cylinders. I read that 130 is low. Should i take the time and do a top end rebuild? The way it starts and runs has me wondering if I should bother? Or am i about to have problems and maybe nip them in the bud this winter?
Thanks ahead of time!

i'm not sure it would even run on only 100# of compression, did you hold the throttle wide open when you checked the comp.? 130 is low, 150 is better.

Checked 2x's... wot... cold. I doubt I have a bad gauge....

100 psi wouldn't make enough power to run at 55, and it wouldn't idle.

I would double check the gauge, and check the O-ring on the part that threads into the spark plug hole.
