Our 74 duster does the same. Just did it. Its been going on for a while and we have a new mini started. Just talked about putting it in tomorrow. Dad couldnt start it after about 4 tries and I got in and got it to start my first try haha.
Got one from Sumit for the 340. Dont remember the price but it was sticking so we had to take it back off and fix it. The magnet wouldnt let go. Other than that it seems fine.
