Got given a carb today, the size of the outlet is 1 3/4, so i am assuming this is how you measure it
. Sadly it did not have a tag on it, so i cannot accurately identify it. No joy looking on the SU carb site either. From what i can gather from the Vizard book, it seems to be an HS 6. Can anyone enlighten me as to if it is, or is it a HIF 6 ?. The only numbers i can find are AUD 8490, AUD 920, on the main body, and AUC 1310 PDCH on the float bowl. I am wondering if there is any advantage using this or staying with the HS 4 currently in use. Engine is a standard 1300 Marina with a Mini sport intake and Maniflow exhaust.
