Hey everyone! First time posting here so I hope I don't step afoul of anything. I've searched high and low thru the forums to find the answer to this question so posting has been my last resort. I am in the process of trying to get my 84 FJ60 up and running. This is my first *car* project (I've worked on a number of motorcycles) and my husband is helping, but for the most part I'm trying to get her going on my own. I've pulled the carburetor--which appears to be an original Aisin--and am getting ready to start the rebuild. When we pulled the jets, we noticed that there were long hairline cracks in what appears to be possibly an outer casing of both jets. They go approximately halfway up the stem. Now, I've never done a carb rebuild and used the original jets (always replaced), however, I am aware it is impossible to get the OEM ones (I've been looking for weeks, fwiw). Bc of this, both my husband and I are unsure if we can reuse these jets, or if this means I should get a whole new carb? Is it worth it to attempt a rebuild on this carb with these jets, or am I dead in the water?
