[MDairheads] 1966 BMW R-27 single idle problems

[BROWNEAK at XECU.NET]

Walt-

Those carbs have an accelerator pump in them. They seem to fail at their 
vintage age. A careful pull apart can sometimes rescue them, but most 
times the internal spring is broken. Unfortunately they are very pricey.

I'm in the process of getting my '66 R27 on the road. Just replaced the 
muffler silent block (hanger) and finishing up the rear wheel bearings.
