Title: Dual Carb Swap
Post by: december2021 on November 21, 2021, 07:05:12 PM
Does anybody have any opinions or advice concerning swapping out the dual carbs on my ‘65 MGB for a single Webber DCOE side draft? 

Should I keep the original equipment at all costs or modify the old girl up a bit?

Also considering upgrading to electrical ignition.  Should I or shouldn’t I?

Many thanks!

The Webber DCOE is way too much carb for a stock engine. It's better to get your SU's rebuilt. Also consider getting your distributor rebuilt and have a Pertronix ignition installed in place of points. Try new plugs & wires, valve adjustment, timing adjustment for distributor, then the very last thing is to adjust the rebuild carbs. Assuming you have good compression those changes will make the car run like it's new.
