Hi Guys,
had a little drawback yesterday. Letting the engine run it stoped for no obvious reason.
After some investigation i found the dizzy finger damaged.
The pom from melted and the electrode came loose  :zap:

The design was bad and i did it new as shown on the drawing attached.

I didn't have time to post when you finally got it running like it should five days ago - but it was great to see and hear that you found the solution and I'm sure you will solve this one too (though it should be a lot simpler)  :praise2:

Michael,
That is one sweet running engine. I am sure you will sort out the distributor rotor.

Fabulous, lovely exhaust note and totally free from any mechanical clatter. I love it! You must be delighted with that!

Nice work! And the engine purrs like a cat. Wish if today small inline 8 engines were still produced for cars or motorcycles.
Any plans to get the engine running again on the speeduino?

Hi guys,
one step forward one step back.
I purchased a pc cooling radiator from china that i will use for the bugatti. Looks nice , just needs some modification.
I made a fillercap and changed the inlet and outlet to look a bit more scale.
The fittings where made out of alu and brass. Also fitted an poket to mount an temp sensor to the radiator.

The step back is my intake manifold. I decided to glue the parts together with epoxy UHU endfest 300.
It clear stuff and barely unvisible. because of that i decided not to use jb Weld with witch i have very good experiences.

Short story: the pieces came apart :hammerbash:

Will redo them with jb-weld. And if i ever build another intake it will be made from one piece.

Hello Michael,

I have bought several of those PC cooling radiators over the years. Some have aluminium header tanks and some are made from brass.

How did you attach the modified filler cap and temperature sensor hardware to your PC radiator? Did you use solder or some sort of adhesive?

Hi mike,
the radiator is made of aluminium. I glued the fittings with jb weld. Have good experiences with this stuff.

Thanks Michael

JB weld seems to be the answer to many problems

I used sometimes UHU Endfest 300. This is also an Epoxy glue. But Every conection failed with this glue sooner or later.

Last failure is my intake manifold. I will toss it in the garbage bin.

That jb Weld stuff works flawless for me till now.

Hi guys,
i am ready with the radiator. Fabricated some holders and hooked it up to the motor. Looks nice and is not leaking so far.
Next would be the starter gear/motor. Till now i am using an cordless electric dril with an free running bearing to start the engine.

So i worked a bit on the new dizzy cap. I copied the design of an full size automotive cap. The electrodes protrude into the cap and are turned half away. The middle electrode will slightly touch the finger.
