The Gilbert 07.
Don't I just love the engine with both the exhaust stacks bolted on? I think the engine looks a proper aeroplane ;D
Also note the plastic tank supplied. It comes in two moulded piece which you join together with a threaded fastner (aka - Screw  :giggle: :giggle:)

In case any one was wondering, the red thing at the first picture is a bobbin with thread supplied for flying the control line model. (Now who remembers Aurora supplying the wax coated thread wrapped on a ply C/L handle with some of the kits?)
Both the engines also come with a spare glow head and the flat metal piece is tool to open up the various parts of the engine without using a monkey wrench and/or pliers and damaging the engine

Coming up next are a pair of Diesels from UK, a 20 and a 40.
Both have been run (but long time back). While the 20 has  seen some use and the box has been lost to time, the 40 has seen just couple of ounces of fuel and the box has survived too.
I guess the 20 could do with some cleaning though. Both are still in good shape, and due to 2T oil pickling have still not stuck up.
Enjoy the pictures

And now comes the 20, though the thing looks scruffy, let me tell you it's just the age but it's still great inside

And the final ones for today.
Guess what going to give the 20 a good bath today :giggle:

Time for some serious big bore glow. It is a NIB piece and a recent acquisition.
From Hungary via good ol'e US of A, a Moki/Mark 2.10 cubic inches glow engine. For those who still have difficulty with their conversions from inches to metric, that is almost 35cc of glow engine and is known for some serious stump pulling power. 
This one is destined to go into a Gold wing 30 cc air frame. Now before you think and say something, yes I would have to modify/beef the firewall to withstand all this and ultimately run the engine rich and rarely would need full throttle.
The pictures are all annotated. So not much explanations needed. Enjoy!!!

If you would notice the low speed needle is adjusted through a disc (similar to Perry carbs) you can see the + and - signs for richening or leaning the fuel flow at low end

The next batch of pictures.
At the last picture you would see that along with instructions, a nut spanner and a feeler strip is supplied so that the tappets could be adjusted when the need arose.

Also happened to pick up an NGH 35 cc gasoline engine while at Blore the Saturday last. Here are the pictures of the engine.

The engine is shipped from the factory either in rear or side exhaust version along with an extra piston. The end buyer can swap the piston, rotate the cylinder and head to make it a rear exhaust version as well.
Similarly while the engine has in built tabs for beam mount like a conventional glow engine, it ships from factory with a set of standoff mounts as well. Talk of options.. :thumbsup:

The last picture at the previous post depicts how the muffler comes from factory. You got to add the gasket between two halves and bolt them together (while joining I would for belt and braces also add a bead of high temp silicone to arrest any leaks etc). Here again you can mount the muffler on the crank either upside down or down side up based on your engine mounting. Yet again preference. The muffler material is thick which should dampen the sound but given the volume of the muffler my take is that it would not be something which would hush the engine. But those internal baffles (see the walls) would sure help)
There are other gaskets as well in the package (some I presume for the optional change of exhaust direction where the gaskets may get ripped off while disassembling the engine and thus need replacement)

After a long time, decided to start running in the NGH 35 cc, in preparation of putting it on the airframe.
Given that gas engines require considerable run in time, decided to do it on a bench.
Took the entire rig to the field today and ran the engine for about 40 odd minutes, one more Sunday of running in and the engine should be ready for mating with air frame.
Here is a short video I took on my phone while holding the entire rig and not wanting it to be pulled off by the engine.
The engine is being run in between 2000-3500 RPM, on 1:20 fuel oil mix, I am using Castrol 2T. Prop is 18x10 wood (Xoar). I have not yet installed gaskets on the muffler and the result is visible in leakage from muffler joint.
This was the first time I had ever started a petrol engine. Had a spinner installed for using a starter if need be, but following the standard drill of choke, pop, and fire the engine fired within 3-4 flicks every time, except once when I had over primed. Then again, with the fuel line disconnected, ignition off and flipping to remove oil, and then flip with ignition on and engine fired right away.
Looks promising to me, but then the real proof would come when it is put in the air.
