I was trying to install my own jet kit and i managed to take off the top 4 screws. I took off the boot, changed the needle, spring, and added the washers.

When i tried to take off the bottom 4 screws i rounded them all and now i dont know what to do.

ANY ADVICE?

 

You should be able to use a set of vice grips to grab the screws to get them off. Another thing you could try is take a Dremel tool and use the cutting disk to cut a slot in the top of the screw and use a flat head screw driver to take them off. Replace them all.

 

Same thing happened to me - managed to use some flat nose pliers to get them out - they are a bitch, and the trick is to loosen them all, working in a star shape, taking them all out a bit at a time. As slippery says, make sure you replace them all, otherwise it makes the next time way more fun...

 

It adds a new meaning to FACTORY SEALED!

 

You need an impact screwdriver. They should be less than $10 at Harbor freight.

 

I would not do that! The screws are already stripped and to use an impact driver it needs to be on a solid surface and it might put too much pressure on the diaphram housing causing it to bend. Just cut a slot in the head of the screws and use a slotted screw driver or vice grips. Good luck.

 

Also, you may try and use a kit like this if cutting a slot does not work:

Worst case scenario you could drill out the entire screw, but that is risking damaging the threads in the carb. Oh and yah, buy four new screws for the next time around

 

The vice grips worked!

 

Do the screw extractors really work? I tried it and made it more circular.

 

Screw extractors can take a little practice to not over or under drill them and to get the bit to bite ... Some guys swear by them.. others at them.

Impact screw drivers are great before you strip something.. kinda a long shot after you've completely stripped them, I think side grinding with a dremel and needle nose vice grips are your best bet now.

You can use an impact driver on your carb.. take off the diaphram cover, remove the diaphram and place in hot water. (dont put the needle and spring in the hot water obviously) Place the flat solid face of the carb on a clean cloth upside down on a bench, hold tool and tap till each screw breaks free, no need to go in a cross pattern removing, just pull them out.

Putting the diaphram in hot water (in theory) keeps it from expanding so it will go back in nicely when you're done... obviously dry it thoroughly before reinstalling it.

Regardless of your method, removing the diaphram, slide, and cap is the best way to get a good solid rest for the carb so you can work on it more easily and smack on it and press on it a good bit without crushing vitals.

Alternative to this is to take two thin pieces of pine or other soft wood (1/2" or greater will do) and use these as buffers in your bench vice, and clamp against the intake/airbox end bells to hold it solid while you work. this gives you a bit more solidarity, soft pine will mash without harming your end bells and give it a pretty solid grip in the vice that wont twist/slide too much. Obviously you're not monster cranking it. If you like a bit of old tire tube rubber folded at least double thick also makes a suitable grippy cushion for the end-bells in a vice.
