I got everything finished with the transmission this past weekend and the car is down off the jackstands. I ran the engine for a cam break in cycle (20 minutes at 2k rpm). After the cam break in was done I started trying to tune the carb.
I noticed it has a vacuum leak that comes and goes. It makes a whistling sound. I have heard that you can find a vac. leak by spraying carb cleaner around the carb and if it is leaking you can hear the ldle go up or down when it gets sucked in through a leak.
If this is correct, then the thing is pretty much leaking all over the base. I think a lot of that has to do with the gaskets supplied with the adapter. They are cut a little bit too big and don't really fit the carb as tightly as they should. Theres also quite a bit of room in the slotted bolt holes to move the carb on the adapter, maybe I'm just not centered.
:
I tried driving it down the driveway and back up again a few times yesterday to get the fluid circulated through the trans. It bogs down right off of idle and you have to give it more throttle than it sould need to get it going without bogging out.
Once it gets going it seems OK though.
We did pull the accelerator pump diaphragm and it looks like it has dried up and hardened a little. There was also some buildup on the jets so I am assuming a rebuild is necessary.
Should I bother with rebuilding it? Its a 23/25 (if I remember right) and its from a 1.6L Escort motor. Is that too small of a carb for a 200? Should I go for the 32/36?
