Carb Questions:

When I picked up my 97 Husaberg, the throttle was completely stuck. After removing the carb I found that it was completely filled with green thick gunk. So I went ahead and took apart the carb and cleaned it as best I could. Now my throttle moves freely and snaps back in working order.

However, when I go to start it, I am not getting fuel. I have never seen a carb like this, it almost has a piston looking butterfly to control air flow. But I am unsure exactly where my fuel bleeds from while completely the air/fuel mixture.

Also just to make sure, can anyone give me the "close" working idle screw set, as well as fuel/air? I marked the locations exactly but I have no idea if they were set right to begin with.

there are several settings that might apply to your bike and it is old now so worn everything and you should only be looking for a guide. some say 1.75 and some say 1.5 so you can't be far away.

tbh m8 you will need to completly strip all the carb down remove all the jets and choke and give them a good clean making sure none of the jets are blocked

Definatly will have to pull all completely apart remove all jets and soak everything (except gaskets, o-rings, or plastic parts) in a nasty bucket of carb cleaner for a couple days, blow all passages with compressed air, find out where the passages come out of when blowing through them and take you time, once it blows out somewhere cover that hole and see if it opens up another passage, make sure you take the venturi off the air filter/inlet side of carb w/two allen head screws, there are two main passages behind the venturi circle thing, make sure none of the carb vents OR vent hoses are clogged, dont drill your jets or passages to clean them, use a garbage bag twist tie, pipe cleaner and compressed air,

fuel gets into mixture chamber of carb through jets, it comes from the fuel bowl which is fed from the fuel line from tank, engine vacuum causes fuel to be pulled from bowl through jets into main air mixture chamber or air passage and into engine, jets fuel are pulled from depends on slide position...oh thats not what you meant? the needle that comes out of the slide goes into the main jet that supplies fuel at wide open throt and mid range, the idle/fuel circuit is the small hole just inside of fuel mixture screw (screw on left) (screw on right controls idle air) both 1.5-1.75 turns out should start it, fuel also comes from start jet which is the one that hangs down into bowl with o-ring on it, i think that pilot jet allows fuel from the small hole in bottom center of passage just closer to engine than main jet

just take your time and do it good, if you cant reuse the gaskets you could get by with matching the o-rings up at a part store and seal on the bowl with fuel aproved rtv untill you get it goin and make sure it runs good, then order a gasket set and any questionable jets or hard parts

all this assuming you have a phm 40 carb
