I love the Webber 2 barrel. Keep it. Same carb used on the 2.5l Defender. The Webber will run rich if the idle circuit is clogged and someone has used the idle speed screw (throttle plate adjustment) to make it idle OK. 2nd choice would be the Rochester.
Ron, do you remember what you run for a Main jet in the Rochester?
Ouch. Those are high wear numbers. Hopefully the different oil helps.
As a comparison, my 200TDI has been getting around 3 ppm of wear metals per 1000 km. You are showing around 20.
I'm not sure if you know, but you can get the oil analysis done locally. Finning is quick and easy and has a nice tracking system.
Or a new battery? I cold started my 2.5NA at -40 successfully, so the starter should have enough grunt to turn it over well enough.
I would do a glue on pan heater. Gregg Distributors has a nice selection that fit well.
Is it your daily driver even in winter ????Update: Left the block heater plugged in this morning and it just started!
Have to buy a bigger magnetic pan heater because it didn't seem to help much and the bigger one is the same price.

It's a brand new battery so shouldn't have issues.
