I'm having issues with my fj40 not wanting to run without the choke. I replaced the PVC valve and replaced the jets in the carburetor. It will not crank with the the choke pulled out but if I don't pull it halfway out after it cranks it'll die and once it gets warmed up it has to be pulled out all the way. If I try to pull it out all the way when the engine is cold it'll die also. I have done a smoke test through the brake booster hose with it running but couldn't fine any leaks that way.
