engine stals when braking/trottle release

[SamBam]

Hi all,

My car is stalling when i let go of the throttle and when im braking. (clutch paddle pressed)
When i shift back it backfires like hell.

Anyone of u technicians know whats wrong?
grtz, Sam

Sounds like your idle mixture jet is blocked

co schroef is verdwenen uit je carb denk ik .:scratch:

Check none of the vacuum pipes are split.
If the idle jet and vacuum pipes are okay, take off the one way valve to the brake servo and see if it's working as it should.

Has the little needle valve popped out of the base of the carb?

[ADITEMALLICA]

may be a vacume or boost pipe come off or loose check all of your jubilee clips are tight on all your hoses and pipes especially around the carb.:)

Ive checked al hoses. All okay.

If i rule out the vacuum of the brake servo. It is still the same. (when braking hard)
The engine stalls when braking. But i use the brake pure mechanical. (no vacuum attached)
How is this possible???

Where to look now?

Could be one of the following - Air leak on inlet, mixture jet blocked, idle c.o mixture too lean, tickover too low??

earth strap getting stretched and/or king lead getting stretched try a new king lead :D

[Tony Walker]

sorry does it idle fine normally and just cuts out when braking hard?

[SamBam]

Idle is unsteady too.

When you adjust the idle mixture does it change at all? Or does it just hunt and idle erratically?

[SamBam]

yes when i adjust the mixture the idlespeeas goes up or down
