Did you plug the line from the brake booster and PCV ? Also, you need to
leave the bowl vent line open, as plugging it WILL affect mixture. Probably
best to disconnect it from the canister, though, to be sure there is no
pressure or vacuum in the line.
> looked up everywhere what else
> effects the mixture
Main diaphragm, bypass valve diaphragm, piston binding, thermal compensator,
idle air bleed, dashpot vents (both bottom and top), vacuum leaks (including
throttle shaft seals), jet position in the body, needle position in the
piston, and float level. Probably more I've forgotten. Oh yeah, fuel.
Gasohol runs leaner than 'real' gasoline and old gas is sometimes even
Also worn needle, worn jet, leaking cold start valve; but generally these
can only cause too-rich mixture.
> is it possible for these needles to go bad
Yes, but only to the rich side. Of course, it's possible someone has put
the wrong needle in there.
