85 RX7 wont idle (carb)
I just bought a 1985 RX7 that is carbeurated. It wont idle at all after the choke has gone in and the engine has warmed up. I took off the filter cover and vacuum lines to find that out of the 4 barrels of the carb only two are actually doing anything. The two on the right while looking from the front of the car are the ones that work. I can reach my hand down there while someone else is on the gas holding at like 1000 and manually open the other two valves to rev it up. I noticed that there is no throttle cable going to the valve so Im not sure how it would ever open. For a temporary fix i opened up the valve manually, stuck in some very thin wire so when i let go it stays there from the spring closing it and it stays open a little bit. it has enough pressure against it to be held there, but to be a little safer i tied the other end to a stationary part of the engine that doesnt get hot. Now it idles well (1500 but ok for now) but its just a temp fix till i find out what the real problem is. Any ideas?!?!?! Thanks

Do a search for idling problems, rough idle, etc. There's plenty of info to be found. Also, look at this possibility as well: http://www.mazdatrix.com/FAQ/SHUTTER.HTM
