There have been internet discussions about installing thermostats without a by pass system used in engines designed for a stat. The rear cylinder on an A may get too hot with potential steam pockets or pump cavitation until the stat opens.
Y, where does one install a draft tube on a stock A engine ? Some run with the B engine larger oil fill pipe. Is that sufficient ?
