Hello
Just purchased a 1985 petrol ducato motorhome but it has come with a number of problems
The speedo does onot work, the petrol gauge is stuck on 3/4 and I think there is a petrol leak somewhere due to the smell of petrol particularly after I put some in. I have looked underneath and the fuel tank looks brand new but has a smearing of petrol on it and there seems to be a small drip in one corner but not from the tank itself it seems to be originating a little above that.

Any help or advice.

Thanks
 
Hello , and welcome to the forum,
is it a chassis-cab , or a van conversion?

new fuel tank points to being insecurely fitted,
probably just the filler/breather pipes,

speedo is Cable AFAIK so worth looking on REAR of gearbox for the bottom nut,

fuel gauge..also poorly fitted sender in tank / wiring I suspect,

Hello
It is a chassis cab thanks for the advice. I have looked at the dashboard end of the cable and it looks like there has been a problem there because it looks like a repair has been tried and there appears to be a bit missing. I will investigate the pipes as the tank is definitely new and as I am not mechanically minded will also get the wiring checked on the sender.
How do you get hold of the manuals.

Hello
All problems (previous problems) fixed now all issues much as described by previous posters on this thread. However it now runs a little too fast when idle. Was informed There is an adjuster screw on the carb to turn but just my luck it is damaged and can't be turned. Any suggestions?

Thanks in advance and for previous advice.

This carburettor is old school and has a mixture adjustment as well as idle adjustment. The idle adjustment screw acts on the throttle stop so winding it in works rather like pressing the accelerator down slightly; similarly unscrewing it will slow the engine down. Confusingly the mixture control also affects the idle speed in that a rich mixture slows the engine and a weak one speeds it up, neither being ideal situations.

You are not supposed to fiddle with the mixture as it affects emissions and I believe there is an anti-tamper device fitted but pre-ECU era folks will doubtless remember trying to tune engines up for more power with this screw. I used to have to weaken the mixture to get the van through the MOT and then screw it in again to get it to run properly:)

It's not clear from the op which screw is seized,the idle adjustment one is very visible while the mixture control is buried in the bottom of the carb body, with possibly the screw head hidden behind an anti-tamper plug.

If it is the idle adjustment screw and it really can't be freed, it may be possible to adjust the speed by a little judicious bending of the fixing bracket.

Hello
Thanks for the advice I will give at a go at the weekend, could you describe the "bending" of the bracket in a bit more detail if possible.

I thought the adjustment screw was threaded through a L-shaped bracket which could be bent slightly to replicate the required movement of the screw (but it's about eight years since I owned my petrol Talbot so apologies if I've misled you over this)
 
Hello no need to apologise it,s joystick that the vehicle is parked away from my house so won't be able to look at at it till the week end and wanted to get an idea of what I would need to do. Thanks again for your replays and your advice.
Andy:)
 
Sorry damn predictive text on iPad don't know where joystick came from should have said just that.
Thanks again
