Stuck Pilot Jet

[stephan]

This is just an informational post for the next poor sucker that has their GS torn apart in their garage and the last thing they needed was a pilot jet that was apparantly welded on.

A left handed drill bit can work well but watch the carb housing itself.  Remember brass is SOFT!  You'll be through the jet and onto aluminum in no time.

A screw extractor should also work.

I didn't have either of those so I used a small TORX (T10 I think) and lightly tapped it into the pilot jet.  Then simply press down really hard and turn and the little guy let loose - yessssssss.  I think just having the force of trying to loosen the jet spread over more points of contact helped.  At least that's what I tell myself!  

Search words:  carb, pilot jet, stuck, seized, torx,  super glue in carb, etc., etc.

Left drill is my favorite ... easy out's AKA screw extractors ... spread the damn thing ... of course I never had my lefties fail ... and once you hit the underside of the head the pilots has nothign holding itself really ... so lefties will work great ... The brass the jets are made of is harder then the cast aluminium the carbs are made from ... I have an idea ... nylon jets ... Yea they had them in the 90's, but unfortunately they made mains only and those were wearing out with fluid flow ... we must have better tech now, so we should be able to make pilots which dont wear but are still nylon ... so if you cant get the jets out ... show it over a candle ...  :lol:

Brass is soft?  Really?  There goes all my Materials Science knowledge...  Perhaps it's brittle and chips away easily under drilling?  That would make more sense to me.  Not to pick at you, just thinking that if the stuff looks like brass but it's soft, maybe it's a softer alloy... :dunno:
