The current engine is the original,runs beautifully smooth but I’d say that’s down to having no lobes left on cam.
Also amazing how forgiving these engines are with a high likelihood it hasn’t had an oil change for many 10’s of miles,by the look of the Black Death in the rocker covers..

I inherited a seemingly blueprinted 3.5 engine with a frame purchase last year ,sold the frame,but kept the engine,so launched into a change out.
Engine mounts seen better days.

Rebuilt carbs using a kit from Burlen,for the cd175 4000 tagged twin setup.
This donor engine has a 20 prefix on the engine number ,low comp 8:13:1 so guessing it’s from a defender?
These carbs have the fixed jet so bought the special tool from burlen uk also to set needle heights on the same level as the bridge as a starting point.
right carb shaft had floating play so changed that and replaced throttle disc.
alloy oxidisation in float bowls but not too bad..

This is all new to me as have been an efi proponent up until this one.
The more I read,watched on you tube etc,reduced the fear factor enough to have a go,and it was the most satisfying thing demystifying how amazingly simple they are,also cleaning them up using new fittings and gaskets ,shiny brass stuff ooooh really enjoyed it.
One thing I did notice,was the float valves that came in the kit are different to the originals ,no longer having a filter on the underside and have vent holes in the top sides..
On inspection,the valve itself did seem to stick a little when inverted before falling freely,compared to the originals which we’re smooth and loose but still worked fine.
Made the call to clean the originals up and put them back in.
Subsequent reading had mention of
these replacements being slightly troublesome,with valves sticking open causing fuel overflow etc.

Had a mischievous minion helping,not sure if the look on the face meant she’d just dropped a nut into the engine or not

Had flywheel de rusted and finished ,cool pattern .
Rebuilt the clutch while in there using the kit from Luke at LOF clutches.
You can see the quality,top notch stuff,affordable too,,note the spring size and setup compared to the original Borg&Beck..
No photo, but the clips he provides with the kit for the throw out bearing and to hold the slave rod are his patented design and brilliant.
check them out on you tube.
Also a fan of the green,but I’m shallow
