An issue I have with the Rascal;

At the weekend, my mate and I did a full headgasket replacement on the van, and at the same time, put on new waterpump, timing belt and HT leads.

After a considerable amount of faffing around, we finally got it running. The timing seems to be a complete pain to get correct, the range of movement for the distributor cap vs where the timing is at TDC don't quite seem to line up, but we then put that down to it running rough when it was cold.

After a short test I then had to tackle the 50-ish mile drive home from Portsmouth. I maintained a reasonably steady 50-55mph for most of the way up the A29.

But when I got nearer home, I parked up to grab a takeaway dinner and then when I got back in the van to do the last couple of miles home, through the town centre, I noticed an issue about the van really not wanting to pull away smoothly from standstill, at traffic lights etc. Very annoying.

is this a problem that has a cure to it? Or is it a characteristic of the van, given that it probably isn't really set up for long periods of high-speed running?

possibly the distributor shaft being replaced one tooth adfirt, a common fault. check the Haynes manual and re-fit.

It would surprise me if the timing was out. I managed a 50 mile journey at a decent pace for the van, but it was only at the end of my journey that things went sluggish again at low speeds.

I went out in it again yesterday evening and all seemed fine on a short run and it picked up speed OK.

Perhaps this is just a characteristic of an older, carb-fed engine that I am not used to?

Mine has done that now and again, usually one spark plug fouled or failed. I keep a bagfull of the old service plugs as standby. (usually No 4 plug that goes).

Nothing to do with age. You are one tooth out on the distributor. Rascals will run with ignition 20 degrees out. Possibly condenser/carb issues as well but sort the timing out first.

Exactly the same as what used to happen on my van and i can tell you i never sorted it!
Although my timing was out by a tooth as well...
I remember it was in the middle of the adjustment before i had the timing belt done by a garage (who serviced a fleet of rascals he claimed).  Afterwards it was right towards to end of the adjustment.  Im told it's easy to pull out the dizzy and move it a tooth but i had the fear back then so never tried it.  But it ran perfectly fine from cold it was only after a good run it wouldn't sodding idle.  I had carb refurbed by dell and a new fuel pump.  I also replaced all the spark plugs, points and condenser. 
Id still say a fuel issue but i'm no expert!
Saying that my engine was pretty smokey!
All in all i miss my van terribly but im glad it's gone!
When it came to my mot day the fuel tank sprang a leak and pissed fuel all over the driveway...not fun.   New tanks for the pick up are £350 from the stealer and i bought a whole suzuki carry 52 plate for £820.

Thanks all for the advice.

it appears to me so far, that it was a plug related issue. I was driving last week when the van cut out suddenly (and as is always the case, at the least helpful place possible, just on the entry to a busy roundabout!) but a quick investigation showed the master HT lead had disconnected itself. I reconnected that, and it seemed to rather perk up quite a lot

However it now has been a little unwilling to start from cold now, but I'm putting that down to the heat at the moment affecting things.

I might have another go at the timing at the weekend but for now, all seems to be going OK

(except for the boot release has now stopped working!)

Master HT lead disconnection is the main cause of Rascal/Bambis exploding exhaust pipe syndrome, I know from personal experience.

Can't say i ever did anything with my ht leads - about the only part that was the same when i bought it as when i sold it.
probably should have changed them but my issue didn't occur on the motorway so i, maybe wrongly, assumed it wasn't spark?
It would always happen after a long run so everything was hot.

Have you cleaned out the one way valve in the tank?

No, I can't say that I have. Will give that a go
