I don't have my manuals yet but they are on the way. Hope to have them next week. In the mean time, I could use some pointers. I have searched the forums and have not found anything much that would help.
71 FJ40 with 78 2F engine. Asian carb.
So, anyway, I bought it about 2 weeks ago and ran very well the first week, accelerated good, idled at 1000, apparently no problems. While driving it the other day, I pulled up to a redlight and it started idling rough and kind of missing and I thought it was running out of gas. Put gas in it still doing the same thing. So I changed the fuel filter and the rubber lines on either end of the filter, also replaced the air filter and plugs. PO replaced the plug wires, dist. cap, and coil wire.
Still having the same problem. It will start and idles pretty smooth. Idles around 1000, will start to idle kind of "rough" and down to about 600 sometimes as low as 500. It usually will recover if I don't try to give it any gas. It does eventually however idle so low it dies. It was running perfect for the first week and I drove it probably 25 or 30 miles, maybe a little more before this problem surfaced.
So, where do I start? I'm thinking in the carb, but what I know about carbs would take me about 30 seconds to tell. Plenty of gas in the tank and it flows very freely when i took the rubber lines off. I can also see gas in the viewing window, about half way up when I shut it off a minute ago.
Thanks for the help and if any of you know a thread I can look in I would look there too. My searches just haven't found anything so far.
Thanks for any and all help.
