I bought a complete factory 6V setup....original manifold, carbs, linkage, fuel log and air cleaner. Upon disassembling the 2 barrel carbs I found one of the secondary carbs had a metering block numbered 2085 instead of the correct #3434. Does anyone know what the #2085 came on originally? Compared to a normal metering block...at least the ones I'm familiar with.... it has a California shaped channel located on the lower left and there are two channels at 5:00 and 7:00 in relation to the power valve. Of course the original secondary metering blocks had no power valve. Should I block the power valve and just use this metering block? or find another? Really curious what the#2085 came on....I've searched the internet and found nothing. Maybe I just didn't look in the right place....
