Re: Boosters


Body of Message

They do fit the Espada. Unfortunately, the one"s I thought were spares may be going into a Urraco. I"ll know more in a few days. As for the vacuum leak, it sound pretty big to cause backfiring. Just a guess, but it may not be the servos. Check the hoses, one way check valve, and accumulator tank under the boosters first. Don"t use pressure to test, use a vacuum pump. If all that checks out, you might have a torn diaphram in the booster allowing a lot of air to get by. Funny it only farts from the pass side. There is an equalization line between the back of the vacuum tubes on the intake manifold. I"d look at that too. That"s kinda hard on the carbs too, fast overpressure can mess things up, and cause a fire in the air cleaner if it gets soaked with fuel.
