Here is the old ovcv diaphragm, could not find a new one
The diaphragm is damaged, I could see the pin hole when I held it up to the light

 

I coated the ovcv diaphragm with silicon , I could not find a replacement part, I guess Toyota wants people to just buy a new carburetor

 

Got it all put back together, runs good, I am happy with it, Thanks for all your help Tim

 

heres is a link to a video of my truck running after the rebuild, it did sound better after I broke it in

 

That's awesome! Glad I could help!

 

Look what I found while stumbling around the net today. A website that not only has full parts diagrams but also has parts for sale from Japan! And they have your carburetor gasket for your airhorn. Part # 17848 for $5.25!! Something else I noticed is the diagram shows a gasket (17841) both on top and on bottom of the air filter element. I only knew of the one on the bottom.
