Carburetor Trouble

Postby stevenstrack » Mon Jun 14, 2010 7:00 pm



I need some help advice. I'm in procees of rebuilding my carbs and I got down to tearing down my last carb #4 and wouldn't you know it the idle screw just snapped off. I would like to try and remove this screw but don't want to screw up the carb in the process. The manual that i got for rebuiding states that it is almost hopeless if the idle screw brakes off. Has anybody had any luck with removing one? I don't want to drill down too far as there is only about 1/4 inch of meat that can be drilled into and i dont want to snap whats left off and have the remainder part of the needle hopelessly stuck. I started drilling using a 5/64 drill bit but think maybe a 7/64 bit with a #2 easy out might be better to use. I already started looking on ebay for a carb for a back up if it is hopeless. Any suggestions?? Or does anyone have one laying around that they wouldn't mind parting with?

Steve
this makes me break into a sweat just thinking of your predicament
i suggest you soak it over night in penetrating oil , heat the outside warm to hot-- centre punch it carefully and drill it with a left hand bit The heat from warming it and the drill bit may be enough to break it free and pull it out
I have had good luck with used carb parts at Crescent moon cycles and they have treated me well, have heard a lot of good things about Cyclepsycho
Good luck & let us know

I am not familiar with your carb, but is it not possible with a small cutting disk on a small dremel to cut a slot across what is left of the idle screw and then again try to remove it with a screw driver (let the carb soak in penetrating oil before you try to unscrew)?
You might also end up cutting a slot in some of the aluminium body of the carb around the idle screw, but that wont harm the carb.
I would think that drilling it out would be very difficult.

Scrap one #4 Carb. I soaked it in PB blaster, heated the Carb, and used left hand drill extractor from Sears and had no joy. The Carb body developed a small crack around the lip of the idle screw. So I'm hoping to get one off eBay. I was hoping to have the bike on the road this weekend but it's not in the cards.

Thanks for info. I found one on eBay and got it cheap, I just hope that it is salvageable. Just waiting now for seller to ship it.
