Hi Guy's- Hope you can help, I have a 1974 vw Bug, 1600, man. Trans.I have a problem with the starter staying engaged, after the eng. Starts.I've installed a new starter and (checked the clearance between the starter gear and flywheel seems to be okay) I installed a new ing.(Two switch's) switch and a starter relay kit( yellow wire to ground, black wire to the small post on starter, red wire thur a fuse to the large post of the starter, and blue wire to the red/blk wire on ing. Switch) hit the key and starter stay engaged. I'm there something I'm missing? Any idea's. Thanks
