Ive been working on the homemade jet kit like the one red posted and i got everything off, the tank the fairings everyyhing. so then i get to the carbs and the screws are really in there tight, i had to take a power drill to get the first two out but now 2 others are stipped and i dont know how to get them out. i talked to my dad and he said i should either take it to the dealer or try to take the carbs off and get it myself or take the risk of using and easy out or just forget about it..i dont know what to do im about to just drop it and forget about it...any ideas?

use a pair of plyer and try to turn it loose...those nuts are really soft...replace them with hex screws afterwards. Been there done that.

That long hose doesnt connenct to anything!,..Try using a dremel and grind a slit in the top of the screw and use a flat head screw driver!

i just came across this thread. the problem with the screws are that they are not phillips. they are JIS. that is why the phillips screwdriver will strip them. if you use a JIS screwdriver, they come out VERY easily. but yeah, after you get them out, switch over to a hex allen screw. then you don't have to worry about it anymore.

one way remove them once they are stripped is to get like a hacksaw blade or better yet, something like a dremel and cut a line in the screw. then you can use a slot screwdriver to get the screw out.

JIS?

 

[sound wave]

quoting from a website:
10JIS - Japanese Industrial Standard
Often improperly referred to as Japanese Phillips. Commonly found in Japanese equipment. JIS looks much like a Phillips screw (and even more similar to Frearson), but is designed not to cam out and will, therefore, be damaged by a Phillips screwdriver if it is too tight. Heads are usually identifiable by a single raised dot to one side of the cross slot. JIS B 1012:1985 screw standard is throughout the Asia market and Japanese imports. The driver has a 57 degree point with a flat tip, parallel wings.

Advantages and Disadvantages of JIS

Most people and companies outside of Japan have absolutely no idea what they are. With the similarity in appearance to the Frearson and the Phillips the screws are often damaged in removing and installing with the wrong tools. JIS tends not to camout like Philips. The JIS driver can be used on Phillips quite easily but not reciprically. Drivers are not easily available in North America, try your local RC Airplane hobby shop. Most RC Helicopters use JIS screws to mount the propeller. JIS-spec cross-head screws are generally marked with a single raised dot or an "X". JIS always fit Phillip fasteners, but because of slight design differences, Phillips drivers may not fit JIS fasteners. (unless the tip is ground down a bit).

DRILL TAP

$2.00 max at lowes and you'll have it for the rest of your life! I used to use them daily, spray some liquid wrench on it, let it sit for 10 minutes, have a beer, and use the tap. Not only will it loosen it, the tap will literally bite the screw and force it out.
