Hey All!
I'm new to this site, this being my first post. A while back I bought what was to be a completely restored 1979 CB750F. For the most part that seems to be the case, with one exception. I found after riding the bike a couple hundred miles that the fuel tank was terribly rusty. I took the bike out of service until I had coated the tank. I re-assembled the fuel tank to the bike, and found that then every carb leaked from the overflow. So, I'm in the process of cleaning and replacing needles and jets etc. My first carb kit came with parts I assume to be from a later vintage than mine. Some parts are the same, but the needles are significantly different. I went back online and ordered the correct ones. Then, when I went to replace the secondary main jet inserts, I found that my original parts are stamped with the number 102, and the replacements are 100's. Should I use the new 100's or clean and re-use the original 102's? They look identical to my eye. Also, are the needle seats replaceable and available, or does a guy only have the option to clean them? Anybody who could use my incorrect needles can have them for the asking. They have a "T" type head without a plunger. Any help you folks give me would be greatly appreciated.
