I am the Products Manager at CPO and while I am familiar with the 1677, I have no knowledge of the "Bigfoot Adapter" My guess is that unless the motor "smoked" due to the additional stress of the 10" blade, the problem is in the switch or connections - you may need to beef up the connections. This saw has a 15 amp motor (same as the 10" Makita) so the power should be adequate. Give Bosch tech a call at 877-BOSCH99
