OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines Finally scored a Victa twin

Hi just scored a victa twin, its not in the best condition but has good compression. Just like to post a few photos of the motor and the unusual muffler. The muffler has a hole in it, any ideas how to patch it up? Also the top nut holding the flywheel on is totally rounded, any ideas on how to get it off? Im very keen on restoring this mower, the base is in decent condition but the catcher is nearly buggered, so ill either get stuck in to alot of plasic welding. It didnt come with a cowling so ill have to search the world for one. Praying that one comes up. Any comments guys will be extremely appreciated. Will post photos of my progress.

The muffler

On FEEbay a few months ago there was a black cowl with a hole on top. Forget what they wanted. It was pricey for a damaged one but not unaffordable.
Hopefully a nice white one will pop up from an owner that has given up on his.

Thanks mate ive been looking every half an hour on ebay and gumtree for the past month. Looks like ill have to be very patient

I was looking at one a couple of days ago that is the half twin with the single cylinder version. Probably nothing off that would fit. The top looks similar but is probably smaller

You sure about that, doesnt look like it, but im sure you know more than me. Ive cleaned it all up now and have posted a better photo. The base cleaned up a threat, its usually the ones that have never been cleaned that come up the best...

Unfortunately with these models, it seems a good base is not the problem, it's everything else that is hard to come by!!
They look nice BTW.

Yeah tell me about it! Still very excited

Hello pavdoum, M-F and Norm,
Great images of the Twin here. Thank you!

I like the base image - with the complex castings that meet
the exhaust manifold ports, and the plate to access the rear spark plug.

This was an expensive lawnmower in the day, and collectable now!
I still describe it as a great folly - similar to the Victa Automatic.

Congratulations!

Hi all,
You must now play the waiting game for parts, will be worth it in the end I'm sure. Just looking at your rounded nut and it doesn't look like a nut at all, either way the only way I can think of getting it off is by drilling a hole straight through as low to the bottom as possible that will take a pice of rod.

A good thick piece that won't bend but you will have to stop the crank from turning somehow, just an idea.

The pulley could be a wack on and wack off type as well, like the older Victa Special starter pulleys. Put a wooden block against the pull cord groove and give it a hit with a solid hammer to loosen. I would try that first.

Another way I thought of is cut or grind away the cup exposing the rounded nut. Then a big pipe wrench. I presume the cup from a125 or 160 will fit as a replacement.

The workshop manual says that this nut is just the standard Victa 13/16" AF shouldered hex starter cup nut. No idea what previous tenants might have done, to get it to its current state!

The drum/cup is toast anyway, so I'd just take a hacksaw to it, to cut it off just above the flat section at the bottom. Grinders don't work too well, on soft metals. That way the nut's accessible for use of Vise-Grip pliers, or a Stillson/Footprint pipe wrench.

Or even, in the worst case scenario, to arc weld a length of pipe with a cross-hole drilled in it to the nut, to get it undone.

The starter drum part number is ST12353A, so it's the same as the Zip Starter cup used on the other full crank engines. And the nut is P/No ST12228A.

Wrong size socket on a rattle gun to get a nut to look like that, I'd say. Maybe they used a multi-hex to achieve that look.
Excellent info as always Gadge.

Very much appreciated guys, thanks. Gadge will take your advice and get stuck in tomorrow cheers

I just put her back together. Thanks to your advice I cut off the starter cup and got the flywheel nut off. I cleaned the fuel tank and carburettor, put it all back together and used a drill to start her up and first go she fired and ran beautifully. In all my years of working on lawnmowers ive never been so happy to hear one fire up. Its loud as, due to the hole in the muffler, so any ideas on how or who could fix it would be extremely appreciated. Just waiting for a cowling to come along, and once it does i will do a full resto on this baby.

You're really getting stuck in. I tend to procrastinate too much.
Hope somebody can advise you on the exhaust and you get your cowl & catcher real soon.

Thanks mowerfreak

With regards to the muffler.
As they are a bit rare, and untill you can get hold of a good one.
I would make a patch, some steel in he right shape, and even put some head gasket off cuts between and screw it all together..... it'l work.
Here's one I did on a Victa..... 125 Mayfair.

Little self tappers .

I had one of those in the 70's , smooth running and reliable .........

good luck, it will go
speedy

I have some twin bits loafing around.
By "Cowl" do you mean the plastic outer cover or the black steel cooling ducting that goes under the plastic cover?
I have a good steel cooling duct you are welcome to if that's the part you need.

I also have a muffler but it is missing the bottom plate. Looks pretty easy to make one of them though.
