@paul0075 has not been able to drive THE JAFFA for the past year or so due to a worn-out engine. Paul's a good friend, and I really like the Jaffa and I don'...

jamesinc Penrite do a specific "running in" oil. Stocked at Repco amongst other places.

I can't really speak for how good/bad it is. That said, I did a bit over 1000km on it in my 242 before changing it for a regular oil. Cut open the oil filter and didn't see anything worrying.

Back from Nats and rather than unpacking the Natsmobile I decided to use my day off to start rebuilding the carbs. Carb #1 has been dis/assembled and gone through the ultrasonic bath (thanks to @dano for lending me said cleaner). I can't put the throttle spindle back in yet as the rebuild kits did not contain shaft seals for it, but otherwise that's one carb down, one to go!

The needle had a bit of scoring on it so time for a new one.

jamesinc Shiny! What did you use as the cleaning solution?

jamesinc

Something like 30/70 mix of degreaser concentrate and water. The degreaser is nothing special, just the stuff you get from Bunnings, I think it's also marketed as driveway cleaner.

You're getting excellent results with this combo without it costing an arm and a leg. I've been using 50/50 Simple Green and distilled water in my 20 litre Vevor eBay Special at 55 C, which gives pretty good results, but Simple Green ain't cheap.

Hi James, what temperature did you set on the sonic cleaner and how long did it take to get that clean.

jamesinc

Massey165 40 degrees and 15 minutes, stopping a couple times to hit it with a brush to agitate the surfaces

Hi James, Can I ask the brand of sonic cleaner, I bought mine online and 2 hours at 60 degrees and nothing like your finish

Philia_Bear Massey165 I just got mine on ebay around 2021. It's a 10L unit. Had a quick look and couldn't find the exact model but it looks similar to the Vevor ones.

I'm not sure, it looks like a generic one to me. If anyone knows it would be @dano as it's his, I'm just borrowing it.

I've found this one, like the others I have used in the past, struggles to pre-heat the bath, but once you run the heater and transducer at the same time it heats up quickly.

Engine is assembled at last, aside from a few small items!

The manifold was media blasted and ceramic coated by Hi-Octane Performance Coatings in Rydalmere, who are the same company that did my B21AT manifolds. Total cost $330.

Here's a before photo for comparison:
