Not sure what to make of this. Maybe it's something completely obvious, but before I start to sort it out, figured it's best to ask the experts.
The engine in my 1969 521 runs strong, all through first gear, all through second, but when I shift into third, I get about half a second of rev, and then it just dies out altogether.
No power. It's as if I shifted back into neutral.
I can bypass 3rd and go right into 4th from 2nd gear without a problem. But if I try for 3rd, nothing going.
Any ideas? Please??
Thanks in advance.
