OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines ARCHIVE: Series 70 Victa Engine Numbers

Hi All,

I have added a guide to a thread in the Victa Engines section on working out the year of a series 70 engine.

This guide is based on my own observations, so, to help verify, and improve it, I would love it if you could grab me the engine numbers of any Series 70 Victa's you have (Full Crank, Starter on top.

If you could tell me the serial, model, carby, and for the plastic carby, what way it faces, and what primer it has that would be great.

i have what i believe to be a series 70 here on my TILT-A-CUT edger.

the starter is on top.

the serial number is 419 000 452 although looking at your other post it seems short? that is all there is though.

carby is either G4 or LM im not sure what one.

primer is white cap facing directly away from spark plug.



just to throw a spanner in the works, the series 80 i pulled from my craftsman i just rebuilt serial number is 424000001. i wonder what that means ill have to get a new crankshaft for that one i think........nice to have the first one off the line if that is what it means series no 424 1980 number 1......possibly but unlikley.

now the hunt starts for a series 80 crank, and the other half of the crankcase because that was stuffed although i could fix it if i get a 5/16 unc tap.

i meant craftsman utility too late to edit post now

It's in there, I'm more than sure of that now, and It actually stands out quite clearly for anything 1976 and back to 1970 (the last to digits of the year are usually 2 - 4 spaces form the start of the code)

I've just run through 20, mowers, and that date code matched the year the mower was released or one year later, for each and every one, including a 63 Corvette!

Have a look at some serial numbers stamped on anything with a G3 Carby, and you should find a 69, 70, 71, 72, or 73 somewhere in the first 5 digits!

Emmo, That's a 1979 you have for the Tiltacut.

For the series 80, I have not started looking at there serials yet, but that could well be 1980, or, being a craftsman, i think it didn't go powertorque in 1984, so the 4 in position 3 could make it a 1984.

I'll dig up some of my S80's when i get the chance, and see what the pattern is.

well the edger is one year older than me i havent started it for around 2 years and it went first pull today im stoked as it wasnt going at all when i got it

Here are some of the serial numbers i have found, they give an example of the pattern i am seeing (Engine, Years Run, Serial):

S70 MK1.0 (1970-1971) - 5270010321
S70 MK1.0 (1970-1971) - 5270033448
S70 MK1.0 (1970-1971) - 527001866
S70 MK2.0 (1971-1973) - 5271051074
S70 MK2.0 (1971-1973) - 5271014993
S70 MK2.0 (1971-1973) - 527202648
S70 MK3.0 (1973-1974) - 44730954
S70 MK3.0 (1973-1974) - 797401401
S70 MK3.0 (1973-1974) - 11074056700
S70 MK4.1 (1974-1977) - 1107508081
S70 MK4.1 (1974-1977) - 1087601265

The 2 digits that start with 7, either positions 3&4 or 4&5 always seem to fall within the years the engine was run.

I was recently given a bit of info from a freind, a red utility, with a plastic carby & cowl with the first few digits 5680 and a corvette 160 with a G3 carby begining with 56903

The way i make these out depends a bit on the engine being series 70 or series 80.

If it has the starter on top, then it is indeed a Series 70, and would be a series 70 MKIV with a G4 (1974-1980).

The serial suggests 1978, whitch would indicate it is one of the later Series 70 MKIV's, I'm guessing it has the white face on the carby, with the primer bulb.

The Corvette would be one of the pre-runner series 70 engines, and It's serial indicates 1969, which would make it the S70 MKI, it would have origginally not had the decompressor, and the G3 carby would have been the type with the black float, and metal bowl.

I'll try and find out about more about the engines.

UPDATE: I cant get hold of them.

Well so far I would have to agree with you.I'm finding it to match as well.Well done good work.

Have you matched it on some 1960's ones yet, I'm getting curios as to them now!

No I haven't I don't have a lot of 60's model mowers here.In fact I think I only have 2 from that period.The other one's I have from that era don't have engines.
