I am in the process of fixing up a victa imperial 16, from my research (and a lot of resources from this fine forum) I have identified it as a very early model HK25F using the walbro GEW.175B2 carb. The mower is in great condition and should look amazing once its all finished(Idea is antique white/with Jarrah rollers) but at the moment I am stuck trying to find a rebuild kit for the Walbro. can anyone assist with a rebuild part number, or if one of the later Tecumseh ones are suitable as I have found replacement units still available. Attached are images of carb and both side measurements. I do apologies for the wonky image I was trying to hold the rule and take a photo at the same time.
