Anyone on here bid on this???

Got pipped at the post. Couldnt justify bidding any more than that.

not me but that would have made a perfect catcher for my victa compact!!

Not me, but it had caught my eye.

I'm not much for electrics, but this one is nice from a collector perspective due to its classic look, feels like something i should one day get to complete th VC-family so to speak!

I wanted the catcher too.
Wasnt sure if i should have kept it or onsold it.

Dunno if there would be a compact/lightweight owner desperate enough to fork out more than $50 for a catcher.

Did victa make a full size electric???

Are the twin and lightweight the same engine to frame bolt pattern as the power torque/briggs???

If somone were to bring me a very good condition (near mint) with labels catcher for my compact they would be walking away with more than $50... I watched a N.O.S one go for over $200 quite a while ago. I do have a catcher for mine but its pretty sad

Yeah i saw pictures of it somewhere, has a big crack in the bottom of it doesnt it???

I have never taken the engine off a twin base but looking at one of my spare engines they are far from being the same of either an old victa engine or a powertorque pattern...

Honestly cant remember where the crack is in it, it has been wrapped in a blanket in my shed for a long time now, I think it was along the bottom though.

Hi Bob,
No, the twin engine is actually bolted to the base by the Cylinders, with the Crank Case supported between. This is because the Muffler is entirely underneath the base, and the Exhaust ports need to be firmly mounted to the base to seal the passage through for burnt gases.

The Lightweight has a similar set up, but in its case the front end of the case that replaces the second cylinder has protrusions for mounting at this end.

Heres a few pics:




Heres the crankcase end for the lightweight:

Thanks Ty


Reason i was asking as i was thinking of having a go at taking the electric motor off the base and fitting it on an 18" base.

I wont ever find a catcher for it so put it on something with a catcher.


I see Reed valve there in the last pic. At 85cc with a reed valve it should have gone OK on a 16" base. The twin would have a bit of poke too.


Bob.

Yep, the twin and lightweight had the carby direct to the crank case with the reed valve, the only victa 2-stroke engines i know of that did not have it through the cylinder.

What mounts does the electric engine have?

Heres the rest of that picture:

I think the electric bases are slightly different mounting to the compact victa engine, I cannot be certain but I do remember hat the base was no good to me but the catcher and everything else attached to the base was....

Thanks Joe. I will check it out.


That picture makes me wonder if a bloke got one of those reed valve assemblies if it could be made to fit on a series 80.

Rodeobob,

considering that there is a G4/LM carby over that reed valve
i would bet it has the same size mounting base as the cylinder mounted intake manifold
so it would fit for sure

Nah the reed valve is part of the inlet manifold I used to have a apare one but it would be way too big to fit over the port of the series 80...

Im sure if i put the cylinder in a mill and machined it flat i could get it to work.


Thats if i could be bothered and i probably couldnt.

I don't see why you would put a reed valve in a port-controlled intake passage unless there was some oddball situation like a multi-cylinder engine involved. Normally reed valves are placed on intake pipes that open directly into the crankcase, so the reed valve takes the place of the piston-controlled port.

Nah plenty of piston port bikes had reeds them.


Stops the intake pulse back up to the carb. Makes it stuff the good stuff round the piston up to where to does whats its meant too.

I guess you'd have to do dynamometer tests with and without, Bob, to see whether it helps. Piston ports give you lousy timing, and reed valves give you lousy volumetric efficiency. Using both together sounds like a very strange choice. Generally, if you want to make a 2 stroke give high power without supercharging, a rotary valve on the crankshaft alleviates both the port timing and volumetric efficiency problems. That is for high speed engines - rotary valves tend to be too expensive for cheapies. A reed valve directly into the crankcase is very good for low speed engines - volumetric efficiency isn't all that good, but it fixes the blow-back problem and gives correct intake timing as well (unlike ported intake systems).

Pretty sure if more go was needed i would just swap in a motorbike motor. Stick with something proven and tested.
