I just got in a new saito 91 fs engine and i can't get the glow plug out! Engine never started or even cranked on a starter! I have a screw driver type glow plug wrench but i can't get it out!! Please help.

Get a proper X type plug wrench.

No need to take it out until you need to replace it.

Try heating up the head a little with a heat gun

if you can't get the plug out with your wrench . you can't get a new in in tight enough.
