along with all bumps and scratches of course. So, it has to come apart obviously so I packed a beer and a smoke in gob, got tools as indicated and pulled it apart...................

Image

Time to do the deed?

OK!

Came home early from work, stuff it, it is Friday after all and set about getting the bits cleaned up and stuff to hand to put the power head back together.

One hour was spent in just removing a thick layer of old varnish (Last owner was religious in application), Fasteners all done, gaskets made, new rings filed up and bore honed and a magnificent "Whoop" lapped out in the cranckase where the tiller bracket casting is. I have marked where it was in texta (Black Chemical Pen that is). Common problem which I spotted before pulling everything apart. I started it last year some time?

Pic of where the whoop was. Mind you it was really big!

Image

Once all of the varnish was removed, some extra letter stamps were interesting.

The letter "R"

Image

Which probbly wobbly, explains the as new crankshaft assy?

Image

So, what does the stamp "A" mean I wonder......Australia? (Could be just a Triangle)

Image

Anyway, smokes, beer and the tools you see...........all together in 11 Minutes. (I left a half fingernail donation in it with the top ring)..........Nose picking finger too, ouch!

Image

So, thats cool! It is as tight as a what name's dooHickee so a heavy oil mix on the weekend in the blue tub.

Image

And, I have always felt that "New Rings", shaped yourself, are really kinda sexy........

Image

Regards

B


PS: I did all the fasteners to the "F.T" specification. I did not touch the big end..................

This post looks more professional without the adjustable spanners.
If the tiller mount had a L, it would be on the left :lol:

But to be fair he tried to hide it..

The 'R' is a stamp applied by the man (or, more rarely, woman(!)) who assembled the thing originally. We don't know (or at leat I don't, and I've asked everyone who survives as far as I know) who had which inital. So it may well have been made by Ron. Or Reg or Richard. Or someone whose girlfriend was Rita. And so on.

The triangle, I have no clue.

Four and three quarter minutes to pull her apart, eh? Well we have to make allowances cos you had a beer nand a smoke. Maybe that's why you were so slow? But don't worry, with practice you can get the time down...

Don't think it is, just the unfinished casting or rust :shock:

Bruce, I would refer you to one of your previous posts.

No the vintage looking picture in the Screen saver post, a sepia picture with two adjustable spanners on the table.

Whoop-Whoop is a small insignificant town in the bush of Australia. It is often used in the Australian Slang expression 'way out in Whoop-Whoop,' which is equivalent to the other Australian phrase 'beyond the black stump,' both of which mean 'way out in the middle of nowhere.' Coincidentally, the middle of nowhere is exactly where Whoop-Whoop is.

The town of Whoop-Whoop has exactly one post office, one church, one pub, and about ten point five houses1 and a total population of 46, which mainly consists of elderly senior citizens and farmers. They used to have a school, but it closed down because the school wasn't being used enough, so the one remaining student has to shuttle into the next town, Jameison (which has a total population of 93), to be educated.

:D

That is easy, it is used to clean his 12 Gauge after the croc shoot.

Two hammers, can't you see Peter one is left handed.

Never mind the Bud, how the hell did he get it stripped down looking so clean?
What's the best stuff to clean off all the dirt and grease? I was thinking of a bath of gunk, is there anything better. I know petrol does a good job but will it be better than the forementioned "Gunk"?

I assume the removal of the flywheel was done by two people, or is there a way you experts do it single handed?

Cheers

You lot do go off eh? :lol:

Flywheel off with it under my arm and "Thunk" with bloody heavy hammer. Try it.

Aww why does some smart eagle eye have to find that Crack in the exhaust port? Why? Stuff it! better than the other sorry lump of a block that is now in the bin.....................Sigh!

OK

It runs, took a bit to get it to turn more than 10 times coz a tad tight but has been running nicely. I did not stop it for ages, compression is up from 14psi and now 62 psi. I monitored block temp of course.

I changed the carb needle to 25:1 thingy, thanks John SOS but mixed 10:1 for initial start up. Is cool, see below....(Click on Picture)

Image

I also found a tank with less dents..................hard ask but worked out well.

So, now to do a bit of a tidy up, have new cable for carb and tilt pin/ thingy (Thanks again to SOS).

There is SO much Varnish to clean off!
