They got it for a good price, and I've made it clear to them that if it is an issue with the fuel pump or a single component I'm happy to cover the costs to put it right. I'm more interested in folks enjoying this hobby than the money.

Hopefully won't be too long before the 110 makes it's way to a meet up. I'm looking forward to driving it enough that I'll be pushing as far as I reasonably can to get her into "daily" use. I really did find myself missing the last one after i moved her on - though in the same breath I swapped that car for the Trabant which has also been a car which has absolutely got under my skin and immediately cemented itself as a permanent fleet member.

Naughty Rover P6 :evil: It could have at least waited until it got its new owner home...

A lot of carb'd cars are grumpy in the heat we've had recently Zel. Both mine can have trouble starting again when scalding hot after a run when under-bonnet heat-soak vapourises most of the fuel in the float chamber and lots of starter is needed get the float chamber full again. The fun of a carb coupled with a mechanical engine-driven fuel pump.

Against that, both mine fire up from cold almost instantly with just a touch of choke to give a bit of fast idle.

Doesn't help that the fuel line routing on the V8 P6 is utterly idiotic. You couldn't really have done more to encourage vaporisation issues if you had tried.

How volatile modern fuels are just makes the situation even worse.

Issues aside, they still got it for a good price so hopefully still get to enjoy it. It was just going to continue turning green in the corner here otherwise!

I'd had recurring issues with petrol on a single cylinder quad bike over the last few years. I'd been running it on E5/Super (obviously) and it was very obviously sometimes running well and sometimes running poorly depending on the batch of petrol I was using. The petrol all came from the same petrol station but sometimes it was good and sometimes it was poor.

I always use E5 in mine and more often than not, Tesco's finest. On occasion I've filled up with the Bat's Pee equivalent or Smell V-Power. I've not noticed any differences between any of them under any conditions.

Surprised you are finding such a difference on your Quad, even with the same fuel from the same filling station Bobins :confused:

The quad bike wasn't in the best of health, but it still ran. On many occasions I couldn't wait to get to the end of the jerry can so I could fill up with fresh - the difference could be night and day.

Sorry if stating the obvious, but the mention of "getting to the end of the jerry can" triggered a thought:

How long is the fuel typically sitting in the can? My understanding is modern petrol ** doesn't store well, goes "off" if you like. Hence if sat in the can a good while perhaps that could contribute to your variability in the quad running behaviour?? :)


( ** modern: as in since became unleaded, not sure about since ethenol added)

The fuel would generally only be in the can for up to two-three weeks, and the quad bike would be running poor from the first fill..... and it was always filled through a fine gauze filter which showed no water droplets in the petrol.

Ah fair enough!

Ruled out an easy fix there, shame!

I have had a can of E10 go from "fine" to "totally non flammable" in the space of a few months. It only took me about an hour and a half of faffing around before I realised the fuel was to blame.

I've never noticed any real tank to tank variation with V-Power, which is what I generally use as it's convenient for me. Tesco I refuse to use unless I absolutely can't avoid if after a contaminated tank costing my folks north of £500 in repairs (along with about half the regulars in what was our local pub back up north - well beyond the realms of random coincidence).

-- -- --

First job today was to try to reattach the fuel pump to the Renault. Who knew the hose I was trying to replace is a different size at one end to the other. Decided to walk away from that before I wound up setting fire to it.

Back to the Rover.

We needed to do something about the indicators/sidelights.

Image

They were the wrong way around (indicator should be at the top) and the sidelights are the wrong type (they're from a P5B I think), and looked particularly goofy viewed from the side.

Image

This is how that corner *should* look.

Image

You can see from the side that everything sits at the same distance from the face of the car now.

Image

I know it was a small thing but it really was bugging my OCD. I wouldn't have minded keeping the chrome backing plate, but the diameter is too small to allow the indicator lens to fit, its own surround fouls on the backing plate.

Image

This is the other reason I wanted to change things: The state of most of the lamp holders.

Image

While that was working it clearly wasn't going to continue doing so for all that much longer.

I confess that the sidelights aren't actually connected yet - I realised halfway through the job that I didn't actually have any bullet connectors in stock. Oops. The indicators I didn't need to worry about that as they came with the looms already attached so just plugged into the connector blocks straight out of the box. I did reuse the indicator lenses as there's nothing wrong with them and the moulding is better quality than the reproduction ones.

Electrical issues are pretty widespread on this car, so I've decided to tackle some of those.

The over reading gauges should be a simple one - just replace the voltage stabiliser. It's the obviously shiny new thing attached to the back of the instrument panel, roughly centre frame below.

Image

Undo the nut holding the old one on, put the new one on and connect the B and I terminals back up as they were before. Five minute job. It looks to have worked too.

Image

The fuel gauge is now showing just a touch below full - it was pegged off scale high before. It probably is still a touch on the high side but far more reasonable.

While I was in there I took a look at the non working dash illumination. Unsurprisingly this was just because the rheostat was dirty. A bit of contact cleaner sorted that out.

Image

A new bulb and some cleaning of the fuse holders got the front courtesy light working.

Image

Similar story with the number plate lights - cleaned the bulb holders and they sprung back to life.

Image

The reversing light was actually working but it got the same treatment.

I have figured out where this black gunk is coming from.

Image

It's the electrical tape that's dotted all over this car which has turned to goo. It's horrible stuff which is like sticky black paint. Rear ones don't work because nobody reconnected the wires to the switches, so they're floating around behind the panel somewhere. That's a job for another day, have removed the bulbs for now so that can't ground itself out and drain the battery (assuming there's anything attached to the lights themselves).

The clock has now been reconnected - and still doesn't work.

Image

Not really surprised, had fully expected it to need servicing.

The main beam indicator has been resurrected. The bulb had escaped from its holder and was rattling around inside the speedometer.

Image

There is definitely something amiss with the headlight wiring. Which given it's running to a random extra switch on the dash doesn't surprise me. Main beam is fine, but on dip both dip and main filaments are lit, which isn't right and is asking to overheat wiring. The wiring in that area we've already established is a mess, so entirely likely could just be connected up wrong on the inner wing junctions. That's where we've left it today. Was nice to actually get an hour to do something when it wasn't ten million degrees and actually managed to achieve something.

Great progress Zel :)

I'm intrigued by petrol going bad. I've never had a problem with E5 going 'off'. Certainly, over last winter, Bluebell sat with an almost full tank and had no issues. I've also, in the past, fired up cars that have stood for years without drama.

My old Saxo sat for a whole year unused and fired straight up when asked to do so... After fitting a new battery...

Modern fuel will last for several years if kept in a sealed container, but the volatile components dissipate rapidly if not well sealed. UK market cars generally didn't have sealed fuel tanks until the late 1980s.

There are 2 grades of petrol - winter and summer. Winter has a higher C4 content and vapour pressure to keep it volatile in colder temperatures. Storing this over summer will likely result in the C4s evaporating leaving the heavier tail, which will probably not work very well as petrol. Summer petrol has lower C4 content / vapour pressure so is less likely to evaporate / leave a heavy tail - especially over winter. As Mike says, stored in a vented container or tank, will speed up the evaporation process - esp of winter petrol over summer. Summer might be mid May - Sept.

I'm hoping this isn't the same C4 as the explosive know as C4 ? :rofl2: :rofl2:
