The choke/filter is absolute. Same as roto 1, 2, 2a. What isnt is the colour of the victa imprint on the top cover...red or black? Or the style..smileyface" or plain Victa?Ive been told many times that the black was for Automatic and red came back somewhere near the end of the run and contined on through model 5 S1. I will ask again for confirmation and something other than verbal proof.
I agree unkie with the Avocado housings, I know the later autos were plain, what I didnt realise is they went painted for so long.
We do know slits were introduced, just not how far into the run. I assumed it was early rather than later, due to the height changing due to vibration. Thus the slit and nut were introduced.
The early model 4 ran a line code of 2.....4 for the later versions. Now there are a few people who claim to know the single digit code., but refuse to share.all the experts Ive asked do not know for sure. For a few years ive been trying to work this out. I have a solid theory that I will share later. Since this is a topic that covers all mowersi dont think it has preference here. Through examples ive seen early autos code 2 and later autos and specials are code 4. Existing codes are Roto 1 majority are nil. Roto 2 ...2, 6, 8 Model 2a 2...Model 3...3. Model 4...2, 4. Model 5...4, 5. Model 6....0, 2. This is general coding, there are variations. Now some believe the codes 2, 3, 4 and 5 applied to options for the model 5 but I find this unlikely since, many codes are the same as their corresponding model. Im of the opinion the codes that corespond with thier model are base codes for a std mower, alternative codes are for options. The other thery was the place of build/state, eg code 2, 3, 4, 5 Sydney. And another was they were production line codes. So as yet no concrete evidence for this. This shoul give you some more food for thought. And as unkie says will need ongoing research. I will try and get a definate answer on the choke colour asap. If your head aint messed, it will be now...ha ha!
