Can anyone explain to me all the parts of the carb and what each one does. Like the needles and jets and mixture screw and all that. I want to get a better understanding on what everything does so I know what I am doing when I take things apart and work on them.

 

Don't be shy everyone

 

Was this a stupid question or what? usually when I make a new topic someone responds within like 5 minutes

 

Why dont you just go out and buy a manual. Its alot better to take it apart and look at things then have people tell you. Bwtf why do you want to know about the carbs ? I took mine apart and I know alot about them now. Also the tube that goes from my carbs right to the valves I ported to match the engine.

 

Well I am testing different main jet sizes and moving the needles up and down so I just want to know what is happening when I do those things. Like is it giving more gas, flooding it more or what.

 

The bigger the main jet you put in, the more fuel you get. As for the needle, if your looking at the flat top, the farther down you move that little link, the more gas your giving it.

 

So when it boggs down when you don't give it enough gas then what do i need to do? move the clip on the needle?

 

When it bogs down it usually is getting too much gas. I would say check your spark plug. If its black its too much gas, if its white, its not enough. You want a nice tan.

 

Hey,

i was searching for the same info not long ago. sorry i don't have a link for ya, but if you go back a few pages in this forum, you'll see my old thread "what do each of the jets do" and it's got some good info in there.

basically:

pilot jet/ air screw - idle to 1/4 throttle
needle jet - 1/4 to 3/4 throttle
main jet - 3/4 to WOT

later,

I have a manual. I am just trying to figure out why it is sometimes bogging down and I would just like to get a little more knowledge. Sometimes it is a lot easier to learn stuff from someone else rather than a manual. Bigmackloud, Thanks for that info. That helps me a lot.
