Trigger points were probably the problem, Debris behind TP arm Options

[oakdalecurtis]

Stock 76 2.0, owned it a long time. Engine ran good sometimes, and then sometimes it would begin to miss intermittently upon hard acceleration. Checked tune, no vacuum leaks, changed spark plugs and wires and replaced throttle position sensor board. No help. I took it to my best 914 mechanic, he said fuel injectors were not firing correctly and recommended I replace the trigger points under the distributor. A member here sent me some slightly used TPs. I finally got around to installing them last weekend. I removed the dizzy (btw, if you only take off the 13 mm hold down bolt and carefully remove the distributor, it goes right back in without changing the timing), to make the TP change. Upon close inspection of the old trigger point plate, I noticed what looked like a small piece of phenolic like debris behind one of the trigger point arms. I don't know if this was the problem all along, but I do know that when I put in the replacement set of TP's and put it all back together, the engine has NEVER run so perfectly. The motor pulls hard from the get go, even when cold, and never misses a cylinder any more. Thank you Bruce914 for sending me the TP's, what a difference they made!
