CAR STILL VIBRATES AND HAS HARD START

1988 Volkswagen Jetta • 350,000 miles

After replacing carb kits and two engine mountings and intake manifold gasket car still vibrates and has hard start. Worse when the fan kicks in.

Did you do a compression test to verify the motor is good?

Is this a carb conversion? Are the jets dialed in?

Disconnect the brake booster vacuum hose from the intake and plug the intake
to see if that makes a difference.

Yes I did do a compression test. When I replaced the intake manifold gasket I discovered that the exhaust manifold had a crack on it

Now what happens is that my brakes would go to the floor sometimes and I've just replaced cylinders, drums and shoes. I did bleed!
