I have used these Winterburn boxes on my hotrod VWs and Porsches through the years. Never had a minutes problem with them.
They are also period correct for my 40 Coupe that's built as an early 60s hotrod.
Winterburn started building these in 1962.

Interesting, had virtually the same results after installing E3 spark plugs.
Using Pertronix ignition.
