Idle Screw Install Catastrophe!


RV00GT

Recommended Posts

I was eliminating my TORS today and everything was going fine, but when I went to tap the hole for the idle screw the tap broke off in the carb! I can get another stock carb fairly cheap, but are there any aftermarket carbs worth putting on a fairly stock shee?

That aint good.

You might be able to work the section of tap loose or break it out or something, but with my experience in aluminum, and taps that have galled up or siezed due to either the tap being dull, not enough cutting fluid, or I didn't back it out to relieve the chips, you're done.

 

How much is a new carb???

Also, see if you can put up a picture of the broken tap in the carb so we can see if its fixable.

IF you can get the tap out without messing up the bore of the slide, and that's a BIG IF, the way I see it you have 2 options:

1) Fill the hole with metal epoxy, re-drill and tap.

2) Take the damaged carb and idle screw to a machine shop and asked them to turn you a new idle screw, one size bigger and drill and tap the carb to match.

Any machinist should be able to spin that little screw in a few minutes.

 

Try to post a picture if you can.

 

Good luck man!

post a picture if you can. like cotton eyed joe said.

 

 

breaking a tap in alumin is one of the hardest things to remove with out damaging much of the thread. was it a 2 3 or 4 prong tap?

 

 

i dont know if "prong" is the proper name but, its the cutters on the tap. if its a 2 or a 4 you might be in luck. you would have to brows through sears or something to find some vise grips or locking plyers that will grip it and you might be able to shake it loose. im not to experience with that sort of thing. i dont do all that much taping at work. also a small pick and a hammer works some times putting the carb in a vise "carefully" and kinda tapping on the flanges of the tap on equal sides at a time, then using very small plyers.

 

 

 

im sure you could also just buy a new carb if the worts comes to it.

If there isn't anything to grab to pull/twist it out, maybe you can drill it out. Then JB Weld the hole and retap or, better option, take to a machine shop and tap a size bigger for bigger idle screw like they said.

If you're not up to doing any of the above suggestions, check to see if the pointy end of the tap is not protruding into the bore of the slide, if the slide can clear the f8#ked up hole and there are no burrs to interfere with the slide, just putty that hole up good and proper so no air leaks in.

 

She won't idle too well, but you can still ride, alternatively, sync the carbs by adusting the slack in the cable at each carb top, once they are in sync, take up the slack at the throttle until she starts to idle.

 

Let us know what happened!

I tried to drill through the tap when it first happened, but I gave up kinda quickly, because I was aggrevated. Is there any aftermarket carbs that I can upgrade to that come with idle screws?

Yep, any one of them. The stockers don't have idle screws on the carbs becuase they're incorporated with the TORS crap. If you upgrade carbs they'll be normal.
