jmj166 Posted September 21, 2010 Share Posted September 21, 2010 Ok, i know this is normally a simple fix with a screw extractor. but what about when you cant get to it with a screw extractor. i'm currently taking my carbs apart from my 81 XS400 and so far about 95% of the screws it it i've had to drill out and use a screw extractor to get out because their all stripped out. I finally get to my carb slide to replace the slide needle with one that has adjustable grove things. but then as i try to take the top part thats hold the top down...they won't come out, i don't wanna just start poking down there with a drill cause i don't want to mess the diaphragm up and put me back 100 bucks ( 50 for each). I've looked at the haynes manual and it isn't very helpful since it lists parts to take out that aren't there. I'd really hate to have to buy a new carb slide and diaphragm just because of two small screws. so I was wondering if any one knew of any other way to remove screws or if i could soak the bottom area in something to help the screws to not be so stubborn. below is an image of the current hair pulling situation. Uploaded with ImageShack.us as always, much appreciation for any advice. Link to comment Share on other sites More sharing options...

Hornix Posted September 21, 2010 Share Posted September 21, 2010 besides some oil it always helps to just give it a little "tick" with a hammer. Or apply some heat. And quality tools is half the job. Good luck Link to comment Share on other sites More sharing options...
jmj166 Posted September 21, 2010 Author Share Posted September 21, 2010 I forgot about using heat, but i'm not quite sure how i could use it without disturbing that rubber diaphragm. And i've learned my lesson in buying lesser quality tools before...the hard way of course Link to comment Share on other sites More sharing options...
Moderator drewpy Posted September 21, 2010 Moderator Share Posted September 21, 2010 support the slide on wood and get your quality driver ibn there and give a few taps with a yack hammer. hopefully that will shift it. other wise you may need to resort to using an impact driver Link to comment Share on other sites More sharing options...

jmj166 Posted September 22, 2010 Author Share Posted September 22, 2010 alright, decided to skip eating during my lunch break and went to the local yamaha place to see if they had any advice as far as if they've dealt with stuff like this before. Mechanic used an impact driver and got the screws out, took'm less than 2 minutes. I only brought one of the carb slides with me, but i figured i know i should get an impact driver for sure now. Plus i'm sure i can use it along the way of finishing my cafe build. thanks for all the help fellas, i really appreciate helping a new guy like me find his way Link to comment Share on other sites More sharing options...
