I was trying to adjust my carb, but where the mixture screw is supposed to be, there is just a brass (I think) plate that doesnt seem like it can be turned. Also, there is a screw at the bottom of the float bowl that has a "hose" attached to it that comes out near the transmission-at the end of the hose is a screw, so it seems you can turn that screw to adjust the screw at the bottom of the float bowl. What is this screw for? and has anyone seen a carb where the mixture screw is a plate like this? I took a picture, but its a bit blurry. It looks like the carb in the picture in Fox's tutorial, except with the plate in the place of the screw: 49ccscoot.proboards.com/index.cgi?board=carb&action=display&thread=429and the screw at the bottom of that picture is the one with the attached hose. |

The long tube with a screw at the end is the drain for the float bowl. Those carbs with the un-adjustable mixture screw are friggin' garbage. I mean WTF? Do these mfg's. think we all live in the same climate and elevation? You should get a new carb and put your jets in it so your setup (plug color) stays the same. Hopefully. Knock on wood.

Damn, never heard of a non-adjustable carb....do you have a suggestion of a specific carb I should get (would like to not spend a bunch, but want something quality)?
Thanks

Thanks Fox. Well, this one definetely is garbage-the other day I was taking it apart to check the needle, and the screws were so overtightened, that it took 15 minutes to get 1 screw off, and the other one immediately stripped-had to drill it out and luckily I didnt damage the threads on the carb body....

If you ever strip a carb screw again, instead of drilling use a hacksaw to cut a slot across the head and then a flat screwdriver will get it off. Then you can reuse the screw. I always put the carb upside down on my bench and push down as hard as I can before I twist the screwdriver to minimize the chance of ruining the screws. I also have a dedicated Phillips just for carb screws. I never use it for anything else so it has a pristine tip. Better grip than a worn Phillips  |

A cut off wheel on a dremel tool also makes a very nice slot for a flat head

Impact screwdriver works on the ones that are still stuck. At that point I'm really not caring if I smash the thing when I give it a a couple wacks with the hammer.
