Yes air/fuel mixture is the problem. Usually caused by a vacuum leak, but can also be caused by incorrect carburetor adjustment.

Hi Guys

I went through My Vacuum Hoses and could not find any leak there , So i leaned my air fuel mixture little more and then raised the idle speed a little more and drove it about 7km,that problem did not occur , i have to run it more and see how it works and also plug the brake booster again and run it a little to check it back ,once i have done i will let you guys know

thanks

Mine does that too.
I don't have power brakes either.

If I slam on the brakes I can here the engine stumble and try to stop.
It usually happens on cold mornings when the engine is cold. It's worse at the bottom of this hill when I leave my house.
My air/fuel gauge will swing to full lean when this is happening and then swing back to normal as the engine stabilizes.

I have always attributed this to an incorrect float setting (SU) BUT I have never adjusted them to find out.

It is caused by a vaccum leak. It can be on one of the other hoses (aside from the brake hose). See Vacuum Leaks.

Hi Guys

I blocked the hose from manifold to booster and and also blocked the booster inlet hose too, but yet i have that issue and noticed that sometimes engine runs on higher rpm than normal and comes back to normal condition again, what do you guys suspect any idea what to go through ?

thanks

Start by unplugging the Brake Booster hose from the manifold, then plug the fitting in the manifold.

Then (carefully) drive it. If the problem no longer occurs, it is related to the brake vacuum.

Hi demacoz

Yes i tried the cluth just before i apply brakes and also i stopped the car and with cluth engaged the gear and pressed the brakes yet it stays idle, only when the car is moving i have that issue but if i apply the brakes smoothly it doesn't die

thanks

have you tried pushing in the clutch before you stop ?

Hi Guys

I have another issue with my B310, On Sudden Braking While car is moving it stalls but otherwise stays idle nicely, When i paddle brakes when the car is stopped it doesn't die ?
It has vacuum brakes on it ,what would be the reason ? from where should i start troubleshooting ?

thanks
