Straight 6 Cylinder Engine

[rdean]

I pulled the head today to see what was wrong with number 5 cylinder. I mounted the head on the valve test plate and applied 60 pounds of shop air. I expected that the exhaust valve was the culprit and needed some more lapping. But there were no leaks from either valve they were good. I checked for suction on number 5 cylinder and that was good also. After close inspection I noticed that the intake valve springs on number 5 and 6 cylinders were different from the rest. I had trouble finding the intake springs and had went to several hardware stores to purchase them. These two springs were much too stiff so I rummaged through all my junk drawers and found two that would work.
As long as I had the head off I made a new head gasket from the same material that I had used on many of my other models but not originally on this model. The suction on number 6 cylinder was not that great so I removed the piston and rod and replaced the o-ring on that cylinder.

The hall sensor is doing fine.

Well here it is.

There is still some tuning to do and I realized that I had never adjusted the ignition timing as it is till on TDC.

Thanks for looking

Very nice. Purrs like an angry kitten!

Sounds good. Have you put a tach on it yet?

How were you able to assess that number 5 was done?

Thanks Robert I expect it will run even better when I have it tuned in.

No Chris I haven't yet but estimate the idle is around 1000 rpm now.

Larry the exhaust stack on #5 was much cooler than the others.

Thank you all for the comments and following along

I have been busy the last few days cleaning, rearranging the shop and building a display cabinet for the 6 cylinder.


I am quickly running out of wall space for model engines.
Karl Benz lives on the north wall.


The east center wall is already full.


And next to them and a little further south are these.


The south wall.



I will now be seriously fine tuning the 6 cylinder and maybe another video.

16 engines in total do you think I have a problem?

Thanks for looking
