Title: Fuel Bowl Screws
Post by: mass-hole on June 28, 2010, 11:11:19 AM
So I was trying to do a tear down of my carbs yesterday and I ran into a problem. I went to take off the fuel bowls, the first screw was really tight, I mean REALLY tight, but i did managed to get it off without damage. The second one on the same carb was even worse. I put the driver in and it just instantaneously shreaded the screw like it was butter. This is one try at getting it out by the way, not even a full turn of the driver, I didnt even get a second chance to reset the driver before the screw was done. Tried one of the screws on the second carb, same thing. So I gave up there to prevent more damage from occuring.

Today I bought a set of Screw-outs from Sears, those things that are supposed to to take out rounded screws, yea right, they just turned the one screw i tried it on into a crater, again in probably half a turn of the screw gun.

Has anyone else had this problem and whats a good solutions. I would perfer not to have to go buy a tap and die set to get the fuel bowls off these things.

Thanks for the help and sorry for the long post,

Jay

common problem.  Most people replace them with hex screws.  If you haven't totally cratered the screw yet, I've had good luck with just filing a notch for a slotted screwdriver, and using a driver with an L-handle to get better leverage.

Kinda like these, though mine has an interchangeable business end.

Cut a slot in the head with a dremel tool. Then grip ir across like a book and it will loosen the hold as well.
You could also drill em out. Then of course put in allen heads.
I sell em as part of my rejet kit ... along wiht jets for your setup ... $25 shipped for all years ...
Cool.

Good idea, I didnt even think about that. I got these things called Screw Extractors and let me just say, they live up to their name. I finally got em out. Good idea on the hex screws, I bought some regular stainless steel hex bolts after i realized how bad the screws were but i just put one on and realized that there are clearance issues for the wrench.

Thanks a lot,

Using screw extractors in a thin as an eggshell pot metal float bowl takes serious nerve, I'm glad I have never had to do it. I always drill if access is difficult and cut if its easy access.
Anyway good its out.
Cool.

I didnt have to drill much deeper into the screw than the head so i was not to worried. Those screw extractors dont take much depth to latch on.

I believe they make screwdrivers specially for those screws.  That might be something to look into for the others.  JIS Japanese industrial standard.  They are designed not to strip with the proper screwdriver where philips head screws are made to just pop out the driver as a torque limiting device
