Reply to "How to Protect 48 IDA from rain"

The poster is worried about water in his engine, when he should be worried about abrasive dust reboring his block with each crank turn. Sure- open stacks look nice and race-tracky; back in the day we could also find a useable block for $100 when the old one wore out. The situation has changed for the worse. USE AIR CLEANERS and save blocks!

As Doug said, the reversion-cloud of fuel/air above Weber stacks will saturate a paper or especially a foam air cleaner with fuel, and Webers never did like cold starts. Backfires are common & so are stack-fires. It melts the secondary venturi in the middle of the stack, the molten metal runs down past an open valve and the next time a piston comes up it finds a lump of freshly cooled carb-metal. CRACK goes a piston and away goes another block. And maybe a cylinder head if you're not lucky. This is NOT theoretical.
