No such thing as a stupid question Sounds like you've done a good job, so should be trouble free for a good while!

They should be tight, the movement is provided by the rubber flexing. Tighten them with the vehicle on the floor at normal ride height or you'll constantly have the rubber stretched and fail quickly. And don't forget done grease on the bolt shanks! They're a right pain to remove when they've rusted into the bush....

Having driven a 2.25 petrol Marshall, Bowie and Gazzar are right on the mark. A V8 would make it a lovely vehicle. As it is, the 2.25 is fine if you're pootling cross country at twenty something, but it's hard work on the road.

Would probably look quite nice with the roof raised a little, but careful with the weight. They got the nickname "magic Marshall" for being fully capable of turning four casualties and a driver into five casualties when (not infrequently) rolled. The anti-roll bars do help, but worth bearing in mind! I'll pm details as they arrive, but sounds like you may have found a candidate

Irritating, but not in a critical place thankfully! If it were me, I'd take a fine file and carefully dress it flat to the rest, fit and forget.

A mate of mine is thinking about selling his 2a Marshall. I'll grab some details if you're interested?

Yes! I set myself up a large tank powered by a DC arc welder. Its most effective!

Looks well "seasoned". The head, if it's not corroded in critical areas might be useful to someone. Crank and suchlike may be OK too depending on where the water got. A good find!

The smoke seems to have been caused by incorrect use of veg oil - not purging back to plain diesel when shutting down. The turbo issue is simply that half throttle doesn't produce enough exhaust energy to spin the turbo up.

The wastegate is stuck open or severely cracked, or the pump isn't supplying enough fuel to create enough energy to spool the turbo up. Have you checked the wastegate actuator?

This usually suggests lack of compression or pump timing out. A compression test and check the timing are probably both good moves

Online is so handy for traffic updates on maps, though. Turn on your phone hot-spot and tether is a good option if you don't want to splash out for the usb 4g dingle. I found the URL text most amusing, BTW

If only. Usually cast or even in some cases sintered (yep, scares the bejebus out of me too). Some are forged from factory in higher performance applications, but only in rare cases they really couldn't get away with cast.

Yeah, it'll be running too lean on the main jet. Whip the carb off and clean it up, it's probably full of old two stroke oil after the petrol evaporated off.

If it's running rich anyway, you'll find the evap problem easily makes it rich enough to refuse to start. The black schmoo is fairly typical, but doubtful it's causing the issue. When things in a carb get gummed up they tend to run lean, not rich. The float height we've been been talking about is fairly critical to proper function. In simple terms, there's a jet (very specifically sized hole) which connects the intake of the carb to the chamber with the fuel in. In front of this there's a venturi which creates an area of decreased pressure in the airflow right where the jet sits. Think of it as a circular wing. The jet is sized so that a specific amount of fuel is sucked up through the jet for any given pressure/rate of airflow. The jet is sat a distance above the nominal level of the fuel in the float chamber. If the level rises, its easier for fuel to be sucked through the jet as it has less far to be lifted. Too low a level has the opposite effect. The fuel level in the float bowl is set by the float, which works exactly the same as the ballcock in a toilet or water tank. Setting it correctly ensures the correct fuel level and correct fueling. A worn jet (yes, the fuel does eventually wear them out and enlarge the hole) can also cause problems. So can a leaky diaphragm in the accelerator pump, so can a leaking gasket, so can a broken float, so can a pitted float valve etc etc... With the carb on the bench and a rebuild kit ready you can cover all those bases and be pretty confident it'll work correctly when you reinstall it.

Mine was so bad it actually wouldn't start! Agreed if it's just a puff of black I'd live with it.

My strombergs suffered from the evaporation problem despite being spot on in every other way. Best working theory seems to be that the bioethanol in modern petrol evaporates more readily than the carbs are set up to handle. This is why its fine if you restart immediately, but ten minutes shutdown and the entire intake system gets flooded with a heady mix of petrol fumes. I solved it by fitting an electric fan pointing at the carbs, which seems to cool them just enough to stop the evaporation and that almost fixed it. I also found that plumbing in a return to tank, rather than having the system ending at the carbs let cool petrol circulate more readily and that was enough to fix it totally.

Fantastic!

It really is. I believe I've got one of those carbs kicking around; I'll make a YouTube of stripping it down if you're really struggling, though.

I reckon you're on the right track with there being a carb fault now, then. A quick rebuild will sort her out.

There's nothing scary in there The hardest part is usually cleaning the crispy old gaskets off. A few pots or magnetic tray for screws and https://burlen.co.uk will be able to supply a rebuild kit which will come with everything you need.

They got to five cylinders. Eventually... I don't know of any on the 2.25d specifically, but they're pretty simple and a common design. Anything covering an old pushrod design will point you in the right direction and the injection pump principal is the same on any old diesel.

I dread to think... Sometimes it's best not to count! She is beautiful, though I might have asked already, but are you coming to Leafers at T'pit?
