82 Toy PU strange running issue - Toyota Nation Forum : Toyota Car and Truck Forums

Hey all!

I just bought a 82 Toy PU, 4cyl, a get me around truck. When I go to start it, even in warm weather (80 deg F) it starts and idles, but seems to miss terribly, and definately wants to die. There is a lot of black smoke during this time, as well. Looking in the top of the carb during this time, the choke is open, and I see what seems to me like too much gas being dropped into the carb.

Here's the strange part: In about 10-15 minutes (of idling) the problem completely disappears. The engine dosen't miss at all, and everything runs GREAT! It is a very immediate change, there is really no in-between. It idles perfectly, and there are no signs that anything is wrong. If you look again at the carb, the amount of gas going in has dropped significantly.

I did the normal things, cleaned out the carb, adjusted the idling screw, etc., but I'm not sure where else to look... If it weren't for the extra gas, it seems like it would be running fine. What controls that flow of gas, and why would it change so drastically? Any other ideas???

Nobody has any ideas? It seems to be flooding out so bad during the startup that the gas works it's way into the oil. The oil I took out of it was pretty thin. Should I be looking to replace the carb, or am I just looking in the wrong place???

I'd replace the carb.

I'm not sure it's the carb. I'd hate to go spend $300 or more on a reman'd carb if I'm not sure. The reason why I think this is because it runs great as soon as it gets warmed up. That means it can properly mix fuel and gas, and afte it is warm, it is all working O.K.

Is there anything else that could cause it?

I thought it might help you all to see what it looks like. This video was encoded with Windows Media 9. It will look best if you have the v9 player.

If link above does not work, just open Windows Media Player, select File, and open URL, then copy and paste this url into it:
