Buy New Carb or Rebuild ?

[Buzzard67]

Hi, Its been awhile since I posted, but my 1984 Toyota Tercel DXL 4x4 Automatic 3-A , 452cc needs help.
The gas pedal has been sticking to the floor, so I bought some Carb cleaner a sprayed the S*^T out of it then sprayed some lube on all the moving parts.
Well that worked for a short time so I thought it's over 30yrs old the Carb could use a rebuild or if anyone has tried a aftermarket Carb that they like I would be willing to do that.
Any help would be great. Any part numbers or price would help to.
I will try and add some camping pictures this year.
Later

Is the big spring on the throttle linkage missing? It pulls throttle back to idle position

[Buzzard67]

All parts , spring and linkage still intact. So....... I dont know.

Have you disconnected the cable to check if it is binding and the same with the linkage? No floor mat interfering with the pedal?

make sure you lubricate the pedal parts and the cable as well. If it runs well, a sticky throttle is not a reason to rebuild it. Best locate the cause and fix it.

a re-manufactured carb is costly and based on experience on this forum, rather unreliable at best (many are junk right out of the box). They are typically about $300. if you can find them. there are still a few companies rebuilding tercel carbs, you will have to buy it on-line and receive it though the mail.

The weber replacement carb is also expensive, but more reliable and simple. it will take some messing with the jets to get optimum fuel economy (not difficult, just another thing that has to be done). as well as fabricating throttle linkage parts and an adapter so it all works well together. Many on the forum have been happy with their weber conversion. I have owned and driven both, I actually like the stock carb if it is in good repair and all of the emissions system are working properly. It has better performance in extreme conditions like very hot weather or very cold. I suspect the factory carb gets slight better fuel economy, but again based on what others have reported, when properly jetted, the weber gets similar economy. The one I had was not jetted properly and got poor economy. I corrected that but I did not get a chance to measure fuel economy after I rejetted it since I sold it.

Depending on what state you live, the weber may not be legal.

Rebuilding it yourself is not difficult, and not very costly either. It is your best bet to make it run good. A rebuild kit is typically $30, sometimes you can get them on sale from Rockauto.com for $10 plush shipping. An experienced mechanic can rebuild the carb in about an hour, but plan ahead and it should not take you more than 2 or 3 hours.

good luck.
