Bruce Macbeth Engine, European Version

That was a very interesting little tidbit Roger - do you have any reference, or was it just told verbaly to you ?

Nice CAD work Achim - I hope it will solve your last problem

Achim,
Have you verified the closing degrees of all your valves. The closing degrees are very important.

Hi Jeff, to be honest, no.
Not so far.
I have only done the adjustment with focus at the opening of every single valve.
At the next opportunity I can do this.
Do you have any values/figures as reference ?


Today was the day of assembling the entire components again.

Wow that looks nice!!

Wow is right! That's Beautiful, Achim!

PS The little red fire extinguisher detail really caught my eye.  Love those tiny details!

[RReid]

That really does look wonderful. The "base as mini-diorama" really sets the engine off well, and also puts it into context.

Achim,
You need to verify valve opening and closing degrees to determine the correct valve duration. When things don't work as expected, it is a logical place to start looking for the problem. Nominal durations: I - 200, E - 220 with no overlap at TDC.

Great to see you have your model running.  It looks fantastic. 

[gbritnell]

Truly outstanding work!  The whole presentation is wonderful!

Pardon my late reply.....

I'm glad to see the final version of this engine completed.

I have to say that I think you are a confirmed detail worker who wants to make it exactly the way you plan it and I admire the way you went about it and I enjoyed every post you made.

If you start something new, I will be following.

I found this by a number of routes. L C Mason refers to a carb with two butterflies, one before the jet and one after and the relationship between them. I have a couple of commercial carbs that I have modified for my engines and noted that the air intake bore was bigger that the bore in the barrel and the engine side bore. If you go to the extreme and make the inlet side bore bigger than the air intake side you will end up drawing neat fuel and no air. For a high volume production finding the optimal bore can be done by experiment. For a one off as soon as you open the air intake past the optimum you have to make a new body

Achim,

I do enjoy the attention to the small details that you and many others on here put into your work

Well that goes without saying    - not that it will prevent me from making that mistake 

Like the rest here - I really enjoy to see your last pictures Achim - amazingly result
