Oh my GAWD. Bring a thread back from the dead just to argue some more. Who gives a ****? Just use the vacuum advance like you want to or not at all. I ain't gonna lose any sleep over it.
I only replied (again) because the dude is just dead wrong. I don’t give 2 runny ***** what anyone does with their timing, but claiming that MVA is THE answer to all that ills the internal combustion engine is foolish. That and beehive springs is his answer to everything. It’s silly.
As I said, locking out the timing is the same type of crutch. And I used to lock out everything, always. Then I set aside my childish, preconceived notions and did some real study and I learned how wrong I was.
That’s all I can say. He is wrong and won’t learn. If an engine needs MVA to idle it has other issues. But by god, GM was using MVA back in the day so that’s how you do it. Not in my world or the real world.
