Hunting Minor

[billygibbons]

Hi all. I have a Morris 1000 Van, (Albert) standard 1098 engine, and when decelerating out on the road, he does a hunting, juddering,kangerooing type thing but if you accelerate, he goes all smooth again. The points and plugs are new and the carb is 1 year old. Any advice will be listened to and acted upon, unless its something like "why dont you get a proper haircut Billy" or stuff like that. Thanks nicely, Billy.

I assume you have checked the carb dashpot is topped up ?

Unusual, the juddering is normally when pulling not decelerating. Lack of oil in the carb damper would also cause hesitation on acceleration.
Could be anything from loose rear axle to broken engine/gearbox mounts. When you rev the engine when stationary do the revs rise and fall in the normal manner?

[billygibbons]

Hi, dashpot topped up, checked axle and engine/g/box mounts, all ok. Yes, when I rev it up stationary, all is nice and smooth and responsive. It runs fine, its only when I back off the accelerator on the road that it does the thing it does. Thanks for the advice though chaps. Just thought, this is the first Minor I've owned, do they all do this? Its not absolutley earth shatteringly drastic, but Ive never had a car do this before

No, they don't all do that. They normally decelerate smoothly with an endearing farting noise from the exhaust.

How about the throttle cable, is it tight or snagging on anything?

[paulhumphries]

Have you checked distributor for broken springs ?

Check engine mounts again - and particularly the engine steady bar. It's not anything to do with carb or dizzy - it must be a mechanical 'looseness' if it's a real juddering. It's not just the farting mentioned above and/or the exhaust clattering against the chassis/body ?

[billygibbons]

Thanks folks. Distributer out at the weekend to check. I know the noise you mean, I call it the George Chishlom sound. It does that thankfully. No, this is a judder rather than a noise. But, I'll firckle with the dizzy and see how I get on. Thanks again. Billy

[bmcecosse]

Nothing to do with dizzy - how could it be ! Look instead at the rear axle spring mounts/bushes. Could be the axle moving about due to loose bushes or even broken spring.

is it when decelerating or when the brakes are applied? if its when teh brakes are applied could be a damaged drum

i have the same on my traveller 1275
when pulling away fine high speed fine keeping at 30 it seems to want to go faster but decelerating it dose want to keep going but not all the time the main thing is doing low speeds 30 40 it wants to go faster
may be mine just likes the speed not going slow strange but i love it
ha ha ha ha ha ha ha ha ha ha ha

is it when decelerating or when the brakes are applied?

Hi, only when decelerating. I think you guys have narrowed it down to something in the engine as I have checked and double checked all the things youve suggested regarding mounts,road springs etc. Maybe I need a Minor owner to drive it and then they would know exactly what its doing rather than going on my description which although I've tried to describe it as best I can, it wont be as good as the real thing. Thanks again folks, much appreciated. Billy

[bmcecosse]

Does it do it if you slip into neutral and just let the car slow down without engine braking ?
Moggyminor - problem here is more likely to be ignition timing and/or mixture related. Check if the vacuum advance is working properly - it's when wandering along at low speed when it should be doing it's stuff!

check tie rod bushes at front maybee perished.

[stevey]

what about engine and or gearbox steady cables/ bars?
