Well today the engine had a nice run ....  The carb setting was found to be a bit rich so it was turned down a little but this ment that the engine did not pick up after a miss ....  So I must look into the chicken feed tank arangement mentioned previously...
 
The spring for the speed control is back to the original one again and now that the engine is well past if first hour of runing gives good responce.
 
I am going to change the water drain to a right angle bend and bung to make draining after a run easier.
 
When that is all done and the engine proved to still run well I will be fitting a generator that I have been loaned with the aim that the electricity generated will run my "G Scale" garden railway ...  Of course there will need to be a control box  but let's get it generating first.  If that fails then I am thinking  of making a water pump to supply water to  a garden feature which would also have to be made !!!!

Gordon, that sounds pretty good to me. Tuning for Speed is available as a free download in the Interwebs, dunno if it is supposed to be or not.
 
What I did with my steam launch engine, I realised that  I was not going to be able to get enough weight to balance to anything like a reasonable proportion, so I just crammed in the biggest weights that would fit. Being a compound twin with the cranks at 90 degrees and the pistons being very different in weight, there was no way it would be possible to do anything very scientific. Anyway, the results are perfectly good, it does not dance around significantly at any speed that it is reasonable to reach. I have had it up to 600 rpm on a tachometer.
 
 
regards
John
