It's got the orings. 1740 hrs. At a guess it was shot about 5 or 600 hrs and another 300 or 400 the needle would be in two. Mind you only one carb the other is perfect. Lyndon

On another note I have overhauled the carbs. Quite surprised to see one carb as almost had the jet needle worn so much on the c clip it has almost cut it clean thru. Lyndon

I'm not quite sure. Manifold to rubber carb mount I had an o ring. Now I fit the trays. They use the o ring to the Manifold. The rubber carb mount now has no o ring or gasket. The manual shows a gasket but not needed for the uls. Thoughts please from someone who had first hand experience. Thanks Lyndon

I'm perplexed. It's a bucket and was expecting it to handle a failure of the needle and seat. This is of no use except the odd drop from a carburetor that is not in good order. It needs a 3/8 or 1/2 drain be of any use. Lucky if I have an 1/8. I will fit some drains that actually may work . Lyndon

Fitting the heads with out the studs makes it a breeze so the push rod orings seat nicely. I've actually bonded with this engine. It's a very nice bit of kit.

It's a four dollar wesfil.

My tool works fine. But fidley but I'm very happy with the circlips.
-
The clearance was perfect. On a note the piston gudgeon circlips are just about impossible to install in a manner that would not be considered rough. I have made a tool and done some trial runs with the old circlips on the bench. I have yet to try it while the piston is on the rod. The special tool is over 500 bucks but does allow you to install the piston in the barrel on the bench which would be very nice. My way won't allow that as I'm thinking I will need all the room plus some. Hopefully on the weekend I will have a go.

Sure won't. It's a long way away but.

Making some progress. I intend to prime the oil pump and fill the engine prior to fitting the top end. That way I won't wipe off all my cam lube. Then I should be able to fire it up with minimal engine turning. Lyndon

I have ordered a set from the UK along with some parts for the carbs that I'm giving the once over. Lyndon

I've painted the cases in a nice Matt black. Came up really nice

Timing Mark and gear

Seal and cirlclip

I've been a bit quiet lately. You won't believe but 17 weeks to get my cam done. I've stopped my build till I sort the engine. I had allowed about five or six weeks all up. Apparently there is unemployed people in Australia. Well when I try to get something done it takes for ever and then it's not done correctly. It's been a comedy of errors. Anyway it's now sorted. New orings in the cases. New circlip and seal. Timing Mark aligned and gear in place before cam. All five dowels in place.
-
Thanks I will get one. Lyndon
-
I think your correct. It's a one off Rotax thread.
-
Does anyone know the outlet coolant pipe thread on the 912 . I'm resealing them and would like to run a tap through them. Thanks Lyndon
-
It has a kit air box. So when I get to that stage I just vent them on the clean air side I take it. Lyndon
-
No air box. Using the Savannah kit one.
-
912 uls. Drip trays for the carbs. Worth while ???. I have no experience with this as I'm building at the moment. Thoughts please. Lyndon

Small world. He is actually my doctor. Been seeing him for 5 years. Never knew he flew plane Lyndon

I have done my gearbox. All was good. A bit of fiddling with the three diaphragms to line them up. seems odd the middle one can't be centered and relies on the others to keep it in place. There is some offset wear because of this. But it clearly works as it's done 1740 hrs and is in very good Nick . Can't believe the new halves were 70 dollars. I still can't assemble my engine as I have issues with cam end play. This is taking a long time to sort but hopefully by the end of the week it can be sorted.

I have thought about this again. The weak point is the charging system. As there is no back up. It that fails you are forced to look for somewhere to land. Not immediately but it will change your plans. with a mechanical pump I could have it fail. The electric pump fail or the charging system fail. Obviously not all at once. If this happens the plane will happily fly to where you were going. So I will just pay the extra and get a nice new mechanical pump. Thanks for the input. Lyndon
