The Engine build has been covered in many blog entries. The build wasn’t straight forward, which was in keeping with all things related to Lady Marilyn, and in order to ensure everything was tip-top it was slow going.
Drakes Engineering in Bradford did a stellar job of the machining work, thy also rebuilt the head for me. The pistons and all the bearings were all new, as were the cam chains, tensioners, guides and seals. Electronic Ignition, courtesy of Powerspark, had been added too.
That’s a whole lot of newness in one package and its always a worrying time when you come to start the engine for the first time.
There had been some considerable space between building the lump and first start, the wiring had been done, all the braking system replaced and many of the ancillaries had been on and off during trial fitting.
However, the time had come. All the bits were on the car, in the right place and ready to rock and roll.
The assembled engine sporting the customer designed Radiator and twin thermostatically controlled fans was in place to deal with the substantial heat output of the engine.
Belts were tensioned and ready to go
and we had a fully wired in Dash to do the job properly.
The inner panels need replacing and they were just loosely placed for the trial start.
One of the issues with Electronic Ignition is that its impossibly to statically time the engine. So the process for best guess location for the distributor had been to correctly set the old points distributor and statically time that. Take a good look at the distributor orientation and replace it with the electronic distributor to approximately the same location.
This was all done and we prepared to launch the start procedure.
I should point out at this stage that the engine had already been turned over with no plugs in place to ensure we had oil pressure before starting.
So, with one pair of hands on the distributer and a nervous finger on the starter button and me hovering with the video, we were ready to go.
Here’s the result.
Then we checked the timing and did an initial carb balance to get a sweet tickover.
Much relief, the engine runs like a song. We’re on the home straight now!
Carb filters were then fitted, the coolant topped up with OAT antifreeze and attention turned elsewhere….
