That legendary fuse-blowing issue is now a thing of the past, so~
Recently though… it seems to have a slight smell? and is leaking?
Let’s take a look at it bit by bit~
This unusually tall negative-pressure carburettor… definitely smells ancient.
Plus it’s a rare carburettor with no starter valve, adjusting air volume with a choke instead.
We’ll fix it to our usual carburettor stand and quickly disassemble it for inspection.
This is what accumulates when the engine shuts off.
Since the hose is black, they switched it to transparent to check.
Pretty dirty… especially cylinders 3-4… I understood the cause right away when we took it apart.
Surprisingly, it had a rubber valve for this era… or did it?
This area smells suspicious too… looks like we’re on the right track.
We removed the SJ cover. It’s a jet specification I’ve never seen before.
The straw corroded and was leaking, so it looks like someone covered it with a gasoline coating agent.
It’s brass, so it would have been better if they’d soldered it…
The spot marked with a circle is where it’s leaking.
They’re working hard, scrubbing away. It must have been pretty clogged.
You can get it shiny without all that scrubbing.
Equipment really saves time and improves quality, so it’s very important.
Cylinders 2-3 were pretty rough, so
We applied gun coat on both the inside and outside.
Today we’re just confirming~
