Pilot screw

Post by gipsy42 »



I took the carbs out of my 95' Aspy, apparently it has never been openned, but;
On the right carb the pilot screw is frozen, no way to move it, I'm afraid to force it (it's a D shaped shaft) and round the head to the point were there is no return.
Have any of you had same experience? how did you solved?
I put some thread loosener, whit no avail. Thinking in heating with a torch (a little) the carb body next to the screw, since aluminum (body) will expand sooner than brass (screw) and then pry it off.
Any sugestions will be greatly appreciated.

A little time in the ultrasonic cleaner might help. Then heat and shock, tappy tap tap.

There are two holes in the bore below the throttle plate. A large on the outboard side and a tiny one on the inboard side. The small one is where the idle fuel is drawn into the engine, get some penetrating spray in towards that small hole, right close to there in the cavity is where the idle mixture screw tapered point resides. Also with carb inverted correctly spray down into the idle mixture jet, it will also work its way down to tapered point of mixture screw. Do use a little heat after some soak time but remember there are rubber O-rings on mixture screw proper. You should be replacing all those seals and O-rings anyway for a trouble free outcome.

This is an update:
The pilot screw is OFFFFF!!,
First I cut a slot in the head of it, applied heat close to 150 ºF, and while I was holding a firm CCW torsion with a screwdriver , my friend was lightly tapping the end of it; after several tries it started moving very slowly, then it gave up and I removed without any damage.
I’ve done many carbs in the last 20 years with Gl’s, but first time with such trouble.
Will be replacing all gaskets and O rings, I have the Randakks kit.
I want to thank you all for your valuable help.
