racerx,

it seems to me that you've opened up your carbs na...did you brush the gasket between the carbs and manifolds with shellac when you put it back?

I had a similar "sinok" and hesitation scenario and it was a vacuum leak scenario.

The manifold is a vacuum space, and small holes because hindi properly sealed ang in-between ng carb and manifold can show this symptoms.

Nasolve ng shellac (actually not my idea but rather the real mechanic who diagnosed my problem) being brushed on both sides of the gaskets....so when it dries up totally sealed.

The shellac (if you're not familiar) is the brown plastic bottle sold sa auto supply store. It's a standard for gaskets as pandikit nito.
