I have a 76 Fj55 that i have been chasing the bugs on. The PO didnt drive it much for 3 years and I want to drive it all of the time. It got to the point where I had chased everything down to the carb and I was dragging my feet on rebuilding it. So then I pulled it off and just rebuilt it.
When I put it back on it ran worse! Whenever I put it into gear it would die under a load, but ran really well at idle. A friend suggested that there may be a clogged jet or circuit. So I pulled it back off and cleaned them out.
So while it was apart, the buddy that was standing over my questioned whether I had put the jets back in the correct place. I swear I did, but he suggested switching them just to see what happened. So I did, and it seems to run great now.
So I am wondering if anyone knows which jet should go where? If I am looking at the front of the carb I have a #30 jet on the left and a #16 on the right. I think I am correct that the left is the primary and the right is the secondary.

I just cant put any closure on this until I know how it is supposed to be. I cant find anything in any of my books calling out what size the jets should be and it drives me crazy that simply switching them to "see what happens" fixed the problem.

Thanks in advance for any commentary!
