OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines Victa Carburettor Timeline

Hi All,

I'm trying to pin down a timeline for Victa Carburettor, i have put below, what i have narrowed it down to so far, if anyone has info that helps narrow it down further, or knows some of the dates to be wrong, please let me know as i would really like to work this one out to help in dating mowers.

3F: 1955 - 1963 (Small Outlet)
3L: 1963 - 1968 (Larger Outlet)
3Q: 1966 - 1968 (First one for 160cc's)
3S: 1967 - 1968 (Alternate released for 160's, This one resembles 3F/L Models)
G2: 1968 - 1971 (Huge Metal Governor Vane - Very little info on this one)
G3: 1969 - 1974 (Smaller Plastic Governor vane, white, then later black)
G3I: 1971 - 1973 (Modified G3 for the Imperial Range, like the G3, but no vane)
G4: 1974 - 1983 (First Plastic one, Has the grey idle Knob)
LM: 1983 - 2011?? (The Later plastic, no knob. Its still called the LM Today??)

Hopefully someone can help me tidy these dates up, and if anyone can help me narrow down the usage of the G2 (I have one, but i have never seen one on its original mower) that would be great.

Also, just out of interest, i have added a poll to find out which one people prefer, if you like, take a moment to vote for your favorite Victa 2-Stroke Carby!

I voted the LM type, everyone hates them, I think they are a good carby if serviced thouroughly.

I think maybe they get judged a little harsh simply for being plastic, but your right, kept well, they do the Job fine, and the LM model seems to stand the test of time, Longest running By far (At least for victa)

i voted LM as well although i thought they were the G4 untill i read this post

Im with Joe. I like em.

Beauty is if they get water in them they cant be damaged.


Bob.

Well, looks like the LM is winning out so far, I can see why, apart from the cut-out being a little fiddly, and the odd issue with the digphram plate, there probly one of the easiest to service (Especially if its just to clean out the fuel section) and they are definatly hardier than one might think a plastic carby would be.

I still prefer the G3, even if just sentimental!

I thought the LM started in 1980/81 as the last full crankers had them. Power Torque came in 1983

Now that i think about it, your right, the Powertorque was the first time i beleive we saw the small plug at the end to change springs, but there was the early LM, where the hole fore the G4 Adjustment knob was simply no there, but the cap was otherwise the same (infact, some still had the stem that stopped the knob from slipping)

I know there wers series 80 Engines fitted with G4 Carby's, and quite a number of them, so maybe 81 or 82, i will see what i can find out, and try to lock that date down a little more.

My 82 model Tilt-a-Cut (Full Crank)with side start has an LM on it. However the Power Torque LM has a different main jet and poppet valve.

What does the main jet of your Tilta cut look like, one long solid brass jet, or a shorter brass one with a white plastic tube that fits in the end?

From What I understand the G4 and its LM derivative was originally developed for the twin and the 85cc

The LM was the replacement for the G$, the Twin was out of production by the time the LM rolled in.

There is a couple of differences, the most noticeable is the G$ has a shorter main jet, with a separable plastic spray tube, while the LM has a longer main jet, with a thinner tip, and an emulsion tube permanently fixed into the stem in the centre of the float chamber.
