I just had three issues develop at once and I got them fixed but now I can't get the car to run right. The issues I had were a leak in the radiator (installed new radiator), a leak in the carburetor (had it rebuilt by a professional), and a vacuum leak (found and stopped leak).
Now in trying to start it and get it running and it will start fine but it will rev to around 3K and stay there, or if I back off the idle speed screw it will turn on fine and run for a second or two and then die. I don't know how the carb guy set the air/fuel mixture screw and I've never messed with it because it was factory sealed. Since the rebuild the guy removed the seal and cleaned everything out, but I don't know if he set it or just screwed it back in to an arbitrary point? My timing is off but I can't adjust it because the idle is so messed up or it will just die.
Lastly, the carb guy put a new spring on the secondary side that controls the throttle valve switch, but I don't understand how that is supposed to work. It's basically a contact driven tps (I think), but the switch is engaged with any amount of throttle. At idle it's not on but as soon as I give it any gas that switch is clicked. Here is that switch:
Should this come on with any little bit of throttle or only at wot? Could this coming on so easily be causing my high idle?
What other info do you need? I had it running fine before but I didn't have an accelerator pump that worked, this throttle valve switch didn't work and I had a vacuum leak so all my previous settings are now way off because all that is working. Plus the carb was rebuilt and I'm sure my settings were messed with when he put the carb back together.
Where do I start? I'm gonna call the carb guy to see exactly what he did but if you all have ideas that would be great.
It's a 1.6L 1597cc engine with a stick shift 5-speed and a 2bbl Hitachi carb
