Guest 39convertible Posted December 23, 2008 Share Posted December 23, 2008 Hi I sit here and wonder if everybody use their exhaust flappers.is it common to take it away or is it a "you must use it" ?i saw that bob´s sell the assembly without it and i havn´t ask them about it.do i have to use it or could i lock it in place, do they really work after a year or is is stuck in rust and carbon after a few miles?please tell me your experience of it.Regards Janne, the Swede with a ´39 66c Link to comment Share on other sites More sharing options...
Matt Harwood Posted December 23, 2008 Share Posted December 23, 2008 I recommend pinning it in the closed position (or the open position, depending on who you ask--the position that diverts exhaust out the exhaust pipe rather than around the carb). The only reason it's there is to help cold weather warmup, and while I know it gets quite cold in Sweden, I bet your car is only going to see nice weather and it isn't necessary. I thought about welding it in place, but my machine shop drilled a small hole and pinned it instead, which is more easily reversed than welding and less apt to damage the casting.I wouldn't buy one without the assembly unless it has provisions to some how keep the exhaust gasses away from the carb pad. I bet Bob's is just selling the raw casting and you have to put the guts in it. I don't think they're selling it this way as an "improvement" over original.Hope this helps.
