So today I unscrewed 2 full turns in the vacuum modulator....still isn't perfect like before, but MUCH better.
I drained a quart and a half from it, and now it's right at the top of the cross-hatched, so that's perfect as well.
Now, cold, it operates as it should. Once it warms up nice and good.
It starts taking off in 2nd again, and the shift from 1-2 is very very soft/sluggish, like it slowly slides in gear. 2-3 is perfect, just like it was before.
If you manually shift it, it's fine.....
So this week, I'll drive it right to the builder, and have him try it, see what he thinks of it, and fix it. I ain't touching it again!
I tryed that old high speed reverse trick to flush out the governor in the tailshaft...didn't make any difference.
