Cleaning the carb on a Baja 5b

hey guys, i just got my baja 2 days ago,, and i got it started, and it runs very good. Now i wanna clean out the carb. I see that it is being held in place by 2 screws, but what are some tips you can give me. Like what is something to watch out for when cleaning it? Should i clean it in pure clean gasoline, or use carb cleaner

If you plan on taking the carb apart, IMO it is best to have a carb gasket kit on hand first. It sucks to take everything apart only to be held up on reassembly because of a torn gasket. Once you have that then, just pay attention to where each part came from. I like to clean the parts with a can of Carbkleen and a paper towel.

yeah have new gaskets on hand and check the exploded views from the ss manual or the walbro site (check sticky's). Compressed air to blow the parts off is ahndy too.

Get gaskets and you'll be fine. Install a ShreadStack while you have it apart. That's one of my favorite mods.

It will leak, probably. The effect would depend on which gasket, and possibly where it ripped. Replace it.

Donít do it IB! You stand a very good chance that the engine will not run right, and you could ruin it.
A good rule of thumb with gaskets is to only use them once.

Two holes are there so it can work in either direction, one hole routes crankcase pulse to the pump diaphragm. If you want to make your own, you can, just be sure the holes are precise.

If it is running well why do you want to clean it? Is it leaking or something?

+100, if it running good why mess with it? You need to search the threads for carb rebuilding and you will find plenty of info.

Don't clean your carb yet if you've only done a couple tanks of gas and it is still runnng good. There's no need to take your carb apart until you need to if and when the youthink it might be the carb when the engine runs like crap and you figure it might be a carb issue if there are no leaks or other issue before checking the carb. If you want just do a search to find carb maintenance on here somewhere just so you can get an idea how to take a carb apart and clean it then when you're to do carb maintenance you'll know how to do it. Another good idea is to take pics with a digital camera when you diassemble it step by step so you have some reference as to where the parts go.

well i just wanna make sure that the carb is clean. Clean carb= longer engine life. From what i can tell so far. The carb is mostly dirty on the outside. When i took the filter off to change back to the stock filter system it was spotless on the inside. So i guess ill just let it be, no problems starting it, and it runs like a raped ape

i remember the first time i took my carb apart. i reused my old gaskets thinking that it wouldn't be a problem, got her all put back together and wouldn't you know it---my buggy refused to start, and it never did again until i took the carb back down and used a rebuild kit. my baja started right up as soon as i got it back together. Now i replace any gasket i disturb no matter how "good" it looks

yeah, when i changed back to the stock filter system from the K&N i had to take those 2 screws out. But only to take them to put the stock filter. didnt changed the gaskets, cause i didnt touch, em, she starts really easy now, since i fixed the choke too.
