Oh those screws! Yeah, those are extremely hard to get out. I'm guessin they are 4mm screws. Maybe 4-40. I can find out more later.

 

ahh thank you please do! they are so hard to get out because you strip them when you do! lmao i found that out. :/

 

they are hard to get out because they are split or crimped at the other end of the screw so that they NEVER come out lol

 

opps... lol

should i find a small sheet metal screw?

 

whatever you put in there you dont want it coming out and sucking into the engine!

 

Found out a month or so ago that the carb on a Raptor 80 is notorious for those screws backing out. My buddy's kid had one and all of a sudden it lost compression. Turns out one of the screws had lodged against on of the valves holding it open. The other bounced around in the cylinder for a while. Needless to say they needed a whole new top-end that was only partially paid for by Yamaha.

I'm not sure if lock-tite is impervious to gas or not but you need to do something to keep them from backing out!

Did you get them out or are they still in there?

 

That's why the thread end of the screw is deformed so it doesnt come out. No locktite is trusted by the factory.

 

Can you apply Loctite and get the screws back in,the "red" permanent loctite should hold.

When you clean a carb you just clean the choke plunger,pilot jet,main jet and pilot air jet.

here a good how to link on cleaning a carb.Disassembly and Cleaning of a Mikuni Round slide Carburetor

Its a slide carb not a CV but all carbs have the same parts to clean.

 

the screws are out and are stripped im just gonna have find some similar sized sheet metal sccrews and lock tight them i guess. and then reclean the carb for any metal shavings that fall.

 

did you try going to a local parts store possibly they could tell you.
