Hi Folks,
Here's my latest problem in the 78B saga:
I timed the car this weekend (10 degrees BTDC). It had been set =
somewhere between 25 and 35 degrees BTDC. At the same time, I =
reconnected the hose from the oil separator/ flame trap to the carb. =
and also the hose from the fuel tank to the vapor separator and from =
that to the canister line, located in the trunk.
Here's the problem. Since doing this, I have developed a new noise in =
the car. As I accelerate, everything is fine, but when I let off of the =
gas, I get a high frequency squeal from under the hood. When I apply =
gas or take the car out of gear, the noise stops. As I shift gears, I =
hear this very loud noise and it goes away as I apply the gas once more. =
The car seems to run fine except for the noise. I suspect that I have =
a vacuum leak, but I'm looking for advice from wiser MG owners.
Does anyone have an idea what this might be?
Thanks for your help,
Tim
