Title: help! frozen screws on carb
Post by dex3703 on 09/24/05 at 13:34:51

Hi,

I'm trying to get my carb apart and some of the screws are frozen. I can't get one off that holds the brace for the choke/throttle (the other one I was able to get off with my electric screwdriver but this one the choke knob is in the way). I also can't remove the 3 screws that hold that cover opposite the choke knob.

Can I dip the carb without removing these, just leave the choke knob and plastic nut out of the dip? Or is it enough just to dip the jets and spray the housing out with carb cleaner and thus avoid totally wrecking these screws.

Thanks,
Derek

This is common. Most get changed for stainless allen head....

Are the screws "frozen" and stripped out too? :P

Do you have a hand impact driver with a phillips bit? You can also smack down on the the bolthead with a phillips screwdriver and a hammer for a similar effect.

You can try to cut a slot in the screw for a straight slot screwdriver.

You can try a cold chisel and hammer to turn it loose.

Then there's the vise grip method, too.

You also have the option to drill out the screws and hope there's enough to grab with pliers....

Not to mention that a bandsaw might work if needed.

Or you can give up and just buy a new carb from Lancer....

_{(how's that ole Buddy)}

when i redid my carb i just used the tube that comes on the side of the carb cleaner and stuck it down the holes,until the cleaner came out the other side,i used about 3 cans (but i spray the sh!t out of it!)when i put it back in, it ran perfectly.

good luck.

I learned my lesson not to use an electric driver, or any driver. It is too hard to control and feel if you are about to strip the head.

Give it three good taps with the screwdriver and hammer as said before, and then turn with a hand screw driver.

Thanks, I tried the hammer trick before I wrote the post, didn't work. Plenty of penetrating stuff, no dice.

I took the suggestion to just use carb spray and am dipping the jets. Hopefully that will be enough.

Thanks
Derek

I was able to get a small file and file the sides of the screw head flat and then grab the head with a pair of channel lock pliers. Luck with it

Why did you want to open it up, in the first place? Any problem?

Yes, it's been running very poorly--sputtering, hesitating, esp when cold when I start in the morning. Also a whole lot more/worse backfiring than when it was new. Problems developed after we stored it over the winter--we put stabilizier in the gas but I guess it didn't do the job.

That is one reason that I always drain my tank and carb in the winter (if it will be taken apart anyway). I never bother with Stabil....

I have to ask....you are using the choke correctly, aren't you?

Correctly? You pull it out when it's cold, push it back in after it's warmed up. I never need full choke. When we first got it you hardly ever needed it.

I HAD to ask....you may not realize how many people buy a bike and don't understand the choke.

So the engine is completely warm when all this is going on?

Yes, it's not as bad as when it's cold, but it still coughs and chugs and just doesn't run smoothly.

Anyway, I got the thing apart, let the jets soak overnight, sprayed the thing with carb cleaner and let it sit, sprayed it again, and got it put back together and it's back in the bike. Bike starts, runs super. I'm about to go ride it and see, but it's much better just idling. It backfires very very slightly off of hard throttle, and one loud pop when you turn the engine off, which it did when it ran well. The Suzuki shop said it's supposed to do this, part of how it deals with emissions. I can handle that.

Anyway, wanted to get back and say thanks to everybody. I'm going to ride it now and hopefully it's a lot better.

cool deal,let us know how it did on your ride

It ran well, no constant backfiring, grabbing, poor running. It still didn't feel as completely overwhelmingly powerful as when we first got it, but maybe that's just my memory hoary with time. We'll see for real tomorrow on the way to work on teh freeway.

Now I have to deal with teh front brake, but I'll read around and put another post for that ifneed be.

THanks,
Derek

I ended up just drilling half mine out and replacing with allens which I was going to do anyway. Not that much of a headache I guess. The screws inside the carb did take a extractor. Couple of trips to get all the right replacements. I've since taken apart the carb several times and it is a snap with the allen bolts.

I meant to add that the 3 screws for the choke mechanism I replaced with allens.

Ran great on the freeway today. Still not quite as powerful as I remember, but a lot better than it was. Thanks for all the help.
