The Victa 18's replacement choke/air filter housing arrived today. I paid a handsome price to get this, which is always a risk on secondhand parts, especially considering this thing is nearly 70-years old. This particular one has had a pretty decent repair made at some point, but functions as it should and looks just fine.

For reference, mine was missing the choke switch and had a broken tab. With the broken tab, the two remaining tabs weren't holding the top piece down, and therefore the air filter. The choke switch didn't prevent the engine from starting and running, and I tried rigging something up, but that still didn't solve the broken holding tab. My OCD tendencies meant I wouldn't be happy until I got both problems sorted.




I've found having the intake choked isn't really needed to start the engine, on mine at least, it will fire off within one or two pulls. However, the choke block-off (last pic above) also forms part of the intake restriction needed for the engine to run properly at high throttle/high revs. I actually decided to remove the choke insert out of the housing after fitting the new air filter, it then wouldn't start properly or rev up either. The lower piece of this filter pod in conjunction with the choke block-off forms just the right amount of intake restriction to allow the engine to start easier and then run properly when the throttle is open beyond halfway.
The same applied with the high mount setup that I briefly had on the mower. The plastic "filter" has a much smaller inner opening compared to the rubber tubing, in turn providing the correct restriction. I verified that by removing it while the engine was running, which promptly caused it to backfire up the tube, in turn giving me a fright.
The drawback with this setup is you can't use an air filter in that housing, the only filtration is the wire gauze which wouldn't stop dust entering the engine.

The "new" housing doesn't have the Victa lettering on it, so I'm not sure it's older or newer than the original that came with the machine. The installation included swapping the new air filter over. After a quick test run, I note you have to be quick moving the switch to the run position once the engine fires, it will quickly die out otherwise. I do wonder if only using half choke would be sufficient. The test run also verified the engine will run properly at full throttle. I keep meaning to measure the revs with my tacho, it certainly sounds super strong at full throttle.


So, apart from regular maintenance, this sort of concludes the Victa 18 project. The starter mechanism will need attention at some point as it's not always retracting, and I might look into clear coating it to lock in the patina. Maybe one day I'll strip it down and completely restore it. For now, I'm content getting it out every now and then to mow the front lawns, purely for entertainment purposes..............which is exactly why I bought it in the first place.
Now, if I could only find one of those elusive Victa Twin's............................
