Brian, That is expensive, just checked my supplier, a meter(39") of 55mm(2.16") dia is AU$96. They know how to get at you. Cheers Andrew

Brian, I think it will be a bit boring😁 Cheers Andrew

Sorry Brian, People have to get on the band wagon on different ign's that are not required for the engine. The Rcexl ign unit required for the "N" magnet is the "LV" of multi cylinder ign system for uneven firing engines, ie:- "V" twins. They have a 4 wire pickup. South pole for #1 cylinder and...

petertha, I changed mine(Jung V Twin) over to Spark, used the RCEXL LV spark box, required two magnets at 90deg apart, first south, second north facing. Done the same with the same engine(Magumn) 20 years ago, still run on glow fuel, spark for better idle and transition. Cheers Andrew

Brian, I just sent you a message. Cheers Andrew

Brian, About half way down on the l/h side. 62cc inline twin. I have built and run the "V" twin https://www.cad-modelltechnik-jung.de/bauplaene-modellmotore.html Cheers Andrew

Terry, Merry Christmas and Happy New Year to you and yours from Me and mine. Great work as usual, the rocker arms almost look cast in the pics. Can't wait until it is up and running. Cheers Andrew

One of the problems with building scale engines, you can not scale down the oil or fuel or air density to suite. Other problem that you found is the sizing of parts for the load. Great work and perseverance on building and getting it to run in the first place. Cheers Andrew

Brian, That looks about right, should work well with points Cheers Andrew

Brian, The cam would be a disc with a cutout where the points would be closed, I would say between 5-10deg, and set for where you would like it to fire. Vintage spark model aircraft engines operate similar, the points are only closed for a short duration as to not over heat the coil or drain...

Write it down, it will leak out of you head over time, it does with mine. Cheers Andrew

Here is one lot modelengineignition - Ignition Modules Cheers Andrew

Congrats on a runner, It sounds healthy, and should be a sound engine. Cheers Andrew

This is a page for the Sparey 2cc twin, maybe you could do something with it Oz : Sparey Twin plan - free download This is the one for the Sparey 5cc Oz : Sparey Diesel plan - free download Cheers Andrew

Brian, I have been thinking about this for a while, I had a look around my parts, had a couple of shrader valves(short), a couple of tyre valve inserts, ( I use them for charging air systems in my models) and a gauge. Yes I know that it is 200psi but that is just what I had in the parts bin...

Brian, That is what happens when you don't do enough, mine has gone the same, would be lucky if I lay down 12" of weld a year now. Keep up the good work, I have been following. Cheers Andrew

Brian, The usual magnet is the south pole, some mark the north pole with the red mark. Also the sensor has a narrow band where it will work, any where from 1/16" to just over 1/8". I have a tester to check the pickups and also to set timing, takes all the guess work out of it. It may be working...

Brian, It looks great as always. Following along. Cheers Andrew

I used a honed edge of HSS, then polish the surface with 2000 wet and dry(wet oil). Cheers Andrew

Hi All, Just measured my allen keys, first is 1/16", then 3mm and 2.5mm, not real good for there size. At least the 3mm is almost there. Cheers Andrew
