I had my 72 FJ40 1F up in Colorado, and it ran fine. Now I live in NC right near the ocean, and it runs very poorly. I am assuming that the jets need to be changed to sea-level. The carb is an Aisin. I read somewhere that the spare jets were shipped with the carb when it was new, so I opened the access bolts to the jets, but the sea-level jets were not stored in the space available; I guess some previous owner changed the jets and just kept or threw out the sea-level jets. I need to know what jets I need for sea-level, and where I can get them (well, and how much they cost). Thx.
