Brake cleaner is similar to carb cleaner but uses slightly different chemicals.It works well enough that I'll use it for carbs if I don't have carb cleaner and I use it as a good general parts cleaner.

You should really remove orings and other seals when cleaning a carb.
Carb cleaner and brake cleaner can both cause damage to them although some cleaners are less aggressive and can be less likely to damage them.
And ultrasonic cleaners can also cause damage to orings either through swelling or straight up disintegration of old worn seals.

Will consider that

Sometimes there's a bit of trial and error to find a good cleaner that doesn't damage plastics and rubber.

Agree

Cylinder

Re: Scott Bonnar 45 ID help jimmywa 07/11/26 01:00 PM

Legend! Thankyou, that’s much appreciated. The engine code is 7509300 so it’s a late 1975 engine, which I guess makes it most likely a 1977 model mower?

The handlebars are a shame, and squished how they are I don’t think are repairable, so I’m searching for some.

Questions On Victa Two Stroke Engines

Re: Victa Runs Then Starts To Stall Man With Cheese 07/11/26 12:33 PM

Update....

When I reassembled the carb I set the poppet valve to the 'A' setting. I mowed for about 15 minutes on full throttle before the same problem of it starting the stall. I left it for the day then set the poppet valve to the 'C' setting.
Mowed with a full fuel tank on full throttle with no stalling. Re-fueled and mowed for another 15 minutes (I live on a large corner block) with full throttle.

I can't recall what the setting was before but would have been the 'A' setting as I recall the revs were lower than the 'C' setting. One thing I did notice is on the 'A' setting when it was idling the revs were very low but doesn't explain why it would suddenly start to stall after a while on full throttle when it was fine before. Anyway I may experiment with another poppet valve and see what happens.

Thanks for your replies.
