End float on the crankshaft is perfectly normal & yours is about the same as every other one.
Make it idiot proof and someone will make a better idiot.

Re: TC 57014 57/58
All sounds perfectly normal to me.
Messy.....perhaps.
There will be a lot of oily goo coming out of the exhaust outlet when you store the motor upright on a rack, and you're probably going to see oil leaking from behind the prop maybe? And maybe even from the water inlets too. All fairly normal to me....
Leaky gearboxes are quite a common thing with most 102's of a certain age.Cut a new gasket for the end cap as this might help. Other than that have a go at replacing the prop shaft bushing as this is another area where they seem to leak oil from. Or the pinion bushing.(tricky)
They will have at least some play in them somewhere coz they're old after all. Add into the mix dubious maintenence and several non-caring owners over the years and this is where most 102's end up.
There's still plenty you can do to improve things but it will mean another strip down and a few more hours of careful work.
If not, keep it topped up with oil and live with the leaks!

Nudge, used the older gearbox that you extracted broken bolt from and still working on the gearbox you "unseized" which will stay as a spare,
And Jon, I was embarrised but pleased to read most gulls have vertical freeplay.
Have never ever noticed that in my 8 other gulls.
This 102 is messy , which *I now accept and know that some was due to me putting too much in on refilling the gearbox and the wear and tear in the rear shaft bush which I not going to attempt to replace. And leaks in the carbie are coming right.
In fact at the time I gave the original carb a really good needed cleaning and I replaced the float bowl holder side but was disturbed I couldn't find a couple of spare amals I thought I had cleaned up and stored. Found them today so I have carefully hidden them again in a secret place for later use .
I have read that squirrels never find about 90% of the nuts they store for winter which is why they go crazy burying so many.
Need to replace 2 washers on the outboard clamp and repair or replace the plastic shaft holder .
Its quite comical that as I now consider the checking of gearbox oil level to be on the same time level as checking the fuel tank.
I find removing different gearbox plugs in different gulls to differ greatly in degrees of difficulty so I spent some time the other morning , about 2am, alternating between running to the kitchen for coffee and gingernut biscuits and mentally creating some homemade tool to make the plug removal a pleasant and swiftly achievable job.
Before I finished all the gingernuts I reached over to wake the missus for her opinion, seeing as she likes to come down to the sheds occaisionally and never fails to voice her thoughts.
She never even acknowledged my presence let alone commented but I noticed 2 of my biscuits had.
gone walkabout.
I know one of her real early ancestors came over from Adelaide ,about 1842, and with a Welsh surname, so I'll let that one go.
Gonna go down the back and run the 102 for 5-10 mins so I can sleep soundly tonight.

Re: TC 57014 57/58
Nice work.
Glad to hear that the "Gremlins" are being forced out of this old dear.
You'll get there with it.
Gently gently with the float bowl banjo bolts as the threads in this area are prone to bad corrosion over the years and strip quite easily. Fibre washers are what you need in here.
The prop shaft bush is quite an easy bushing to replace provided you have a good heat source close to hand. This is perhaps one of the areas on a 102 gearbox where a lot of oil will leak from during fair useage. This and the pinion bushing are the 2 main culprits for oil loss. (and water ingress)

Re: TC 57014 57/58
Good advice about leaky gearbox.
I finally replaced the gearbox , which had really excessive shaft play and excessive movement in the rear shaft.
No wonder it was losing oil so fast. Did not choose to repair.
Decided to use the unseized original gearbox which I had worked further on, spinning nice and freely and also got am impeller aboard.
Seems great
Another learning curve .
Next I'll be working on the latest 300 hp v6 4 strokes.
