what if the screws were hit by a drill bit and took out the top. I can't adjust the screws do to po drilled the caps out and messed up the top of the screw. Any ideas. Thanks Dan

reverse drill bit. drill slow when the big catches it will back the screw out. or a small drill bit and drill a line of holes. then remove the stuff in the middle to make a new slot.
 
thanks for making this post, I'm going to buy and awl tonight if i have time.. I dismantled all my carbs and broke 1 of the pilot fuel screws.. I hope i have good luck removing it.. I tried sewing needles and such, no luck it's really stuck in there good maybe the extra length of the awl will press it right out.
 
Ok, my awl isnt the correct angle, but i got it removed by manipulating a thumbtack.

the night is ok afterall.

I used thumb tack with a screwdriver on top, put a Popsicle stick between the body and the screwdriver which gave me better leverage and kept the carb body from getting marked up. Good luck.
 
I'm ordering a Suzuki Carb Repair Kit today along with a service manual. When they come in and I get my carb cleaning fluid, I'm going to try this. Thanks for inspiring confidence!

Dude, do some research before you order anything. Check the Newbie Mistakes thread linked in my signature and search out Basscliff's website for a free factory Suzuki service manual download.
 
Thanks for that link. I should clarify that I'm ordering only the new rings and pilot screws. I'll definitely be trying to download the service PDF. While I'm at it, I don't see the harm in taking Bikecliff's advice and finding a new petcock, as the current one was constantly set to prime by the PO.
 
Hi,

this is my first message here, sorry for the bad english, language skills are quite rusty at the moment.

Found this topic seeking solve for my problem with RS40 pilot screws. I solved my problem other way, and wanted to tell about it, if it could be helpful dor someone else. In my case this I couldnt operate like starter of the topic. So I had to do something else, I found at my garage few items and made a tool, it took apprx 10 minutes. And another ten minutes to remove the pilot screw tips.

1pcs M6x25 screw, 2pcs M6 nuts, 1pcs welding machine jet ?0.6mm, 1pcs ?0.5 mm drill bit and little piece of flat bar (cutted dimensions 8x20x38mm, can be smaller dimensions), drilled ?6.5mm hole center of it.

First: shorten welding jet, both heads. Thread head there is cone shape in, that must be cutted away, because it wont support the drill. Should leave 2-3mm thread still on the jet. Other head must cutted because u need space operating in the carb. Open holes after cut with sharp knife or drill.

Second: set one nut on the jet. And screw+nut to the flat bar, after that U can set the nut+jet to them. Tight the nut-jet to screw.

Third: cut drill bit, length: welding nut length+2-3mm. After cutting, dip other head of bit in grease and push the greasy head in the weld jet. This keeps bit in jet when U wawe Your hands of succes all around.

Fourth: set the tool in the carb. Start tight the upper nut, keep the tool straight as possible. Be careful, better slow motions than hasty hardtechno-moves head full of speed. U notice right away when tip is fallen. It might not fall straight down, but U can drop it using full length of 0.5 drill bit and fingers.

Easy, fast and You dont have to dismantle whole carb.
