Back at it

I finally got some time to work on the Lotus tonight. The first task was reconnecting the coolant hoses and temperature gauge. Hooray!

Here is one of the vernier cam sprockets from QED. These eliminate the need for offset dowels and let me set the valve timing accurately.

There still seems to be a lot of interest in this blog. I noticed a lot of people visit my Weber 40 DCOE 149 disassembly notes. Any engine or car pictures take 2nd and 3rd place. Good stuff.

Lotus air box

Ideas for a future project - I have a fibreglass cover, now I need to think about making a back plate.

2000E gearbox info

I bought a semi-close gears and spare gearbox parts on the weekend. For future reference.

New battery arrives

I ordered a new Braille battery for the car, and its surprisingly small.

Update

I've been busy with work and life recently, but the Lotus is still on my mind. I got some time to work on it last night.

The new carbs are now ready to go in, and I re-did my calculations on the valve timing. If the weather holds up, I'll take my first crack at it this week.

Weber 40 DCOE 149 Saga

It's good to work on the Lotus again.

The Weber 40 DCOE 149s are strange animals. The auxiliary venturis & chokes are held in place with brass tubes running from the top, through the body, into the mouths. This locking system is not used on any other models of this carburetor, and there is no information available on the Internet.

After hours of frustration, I found the secret: to change the chokes and venturis, you must "pop the top." Once you figure this out, the tubes clear the inlets and everything comes apart easily.

Many thanks to Gordon Raymond for the help and advice.

New (used) Webers found

I found a nice pair of used Webers on an enthusiast site. The price was right, and the 149's allow more adjustments.
