Carburetor problem

Post by Eyeball »

So my car doesnt have the power my old car use too or get up and go (not really power), so i started looking all over for bad vacuum lines. Couldn't find any but i did notice the secondary butterfly inside the carburetor was not opening. I looked all over the linkage to try to find something missing but nothing was. I would cover the carburetor a little and notice the diaphragm would actuate however it wouldnt open the butterfly or spray the 2nd jet.. i could do it manually with my finger of course, it just seems there would be a spring there or something.. has anyone gone through this before? Maybe someone could give me a couple pictures of their linkage and secondary diaphram? I will make something to open it if needed but i don't want to mess anything up! Thank you for any advice in advance!

I would remove the diaphragm and apply suction to it with a removed vac hose. Does it hold vacuum? If it functions I would check the vac hole in carb to see if its plugged by blowing air in.
Use a good quality Phillips screw driver cause those screws are usually pretty tight.
Love those Tercell 4x4 wagons but they sure suffer from road noise.

The secondary is vac operated, so make sure the diaphragm is good, and nothing is stuck.

It is a manual, so i looked and looked at it again and figured out the diaphram arm came off ,the clip i guess disconnected when i had it apart for a little overhaul of piston rings and some extensive head maintenance., still ran a little rough when i put the clip back on so i went from 10 degrees advanced to 15 degrees and it seems to run ALOT better and have a decent amount of power to get up hills (all 62hp). Like i said though i appreciate everyone giving some input on what would be the next step.
