I am not sure if all of them are still available. A safe starting break in jet suggestion to avoid running too lean on a fresh rebuilt powerhead. SST 60....74D....after break in 73D or 72D Mod 56 production (sand cast) fishing block bridge port.....76D Stock and Mod foam cast oval port with large carbs.....76D minimum and be careful especially with a ported powerhead.....some need to run larger jets. Stock 56 fishing blocks and 49 stock block are normally OK with their original jets. This thread has a post with all the part numbers https://www.screamandfly.com/showthread ... jet-part-s Another option is to buy a set of drills and enlarge small sized jets. |
