Does anybody here have the float height settings for a CVRT carb? I have the J60 EMERs which are very useful, but they don't seem to contain this particular bit of information.I thought I'd better check it on the carb rebuild I'm about to undertake.  

Thanks in advance,

It really isn't easy to judge engine speed with all the other noise going on. Being a shorty, I can keep a good eye on the RPM gauge in the dash without too much hassle. On the odd time I was hatch ornament in our Spartan, I could see the RPMs the other driver was achieving (sensible ones) and hear the exhaust (which you can't from the drivers position) and found the exhaust note quite alarming!

Interesting, I don't think I've got that problem as I've fitted an electric booster pump just before the filters. I think if there were pin holes I would hear it ticking away as it sucked air. I tend only to use the pump at start up but it might be worth switching it on when going up hills to see if that makes a difference.

On our M55 the electric pump we fitted aided start up, but restricted fuel flow when power was required. We switched back to the mechanical pump and the issue went away.

We've had the bling Ferret, and look what happened to that!

 

Whatever did become of that Ferret (aside being put up for sale at silly prices on multiple occasions)?

Having watched the Honest John video, it seems a lot of work to fire 1 missile! I count 3 specialist trucks (albeit based on common mechanical components), a specialist trailer and then  M151 and M35 vehicles for command/control and troop transport. Can't help thinking a medievil catapult and a dustbin full of flaming grease may have been easier...

Our M55 in happier times. Interestingly I have seen a picture of one of these trucks with a matching trailer which has the same size load bed! 

Having driven an International Harvester M55 (with Continental 6602 Gasoline engine) on more occasions than I'd care to, they do sound like a heard of aircraft when driving through built up areas. I also noted that the exhaust is just at the right height for smoking out posers in soft top BMWs at traffic lights.... as for brakes and turning circle, the less said the better! Although specified for carrying Honest John resupply loads, our one never had the Honest John mounting frames installed. The firepower museum also had one that was fitted with the tie downs. 

Resurrecting an old thread again, does anybody have details on setting the float height on a CVRT carb? I'm contemplating building up a good one using a rebuild kit and it would be good to be able to check that the float heights are correct.  Doing this on my MUTT made a big difference to how it runs! And yes I still seem to be taking Spartans to bits as suggested further up the thread...getting there slowly!

Terry, annoyingly that's the same side as the one I already have. Thanks for taking the time to post a picture. 

Thanks Terry, I  shall be checking which one I already have on Sunday. The one pictured is a drivers side one. 

I work on the railway and we had a massive issue with biological growth in our fuel. We now have a rig which treats all incoming fuel deliveries (automatically) with a biocide. The issue became more prevalent when the sulphur content of fuel was reduced, as this kept the bio in check. Lets not forget that oil started out as organic material.  

Be aware that this issue will only get worse in future as the bio-fuel content in fuel increases. 

Thanks. I shall check which we have over the next couple of days. 

Which turret side bin do you have Terry? I have one (can't remember which side so will check), but still require the other. 

At work our drivers have taken to colouring in the LEDs they feel are too bright with felt pens...seems to do the trick though!

It's possible that the pump flow is insufficient to keep up with the engine. We installed an electric pump on our M55 truck with a 9(ish) litre petrol engine (suffered evaporation and required priming if left for over a week) and it cured the fuel evaporation issues but wouldn't keep up with the fuelling requirements on the move. We switched back to the manual pump and she ran fine again. 

I would be vary weary of doing anything with wheels, with the typical attrition rate being 30 miles of driving between a tyre becoming de-bonded and coming off the rim (necessitating a wheel change). The wheel is then effectively scrap.

In the steam railway world we leave new cylinder castings out to weather for as long as possible before machining.  At least two of our out-of-ticket locomotives (which won't be in the overhaul queue for a while) already have new blocks sitting outside. These should be well seasoned by the time they are required for machining. Lack of cylinder block seasoning was a problem in some locomotive classes when constructed from new, and they required much remedial work and ultimately new (seasoned) cylinder castings .

Pretty sure I remember seeing some plastic tracks on a trials/development CVRT that was in Withams some years ago, but as for any further information I haven't seen any.

A guy I saw on you tube buys a new tarp every couple of years to cover the originally  supplied cover, he has got 10 years out of the original cover this way..... not sure that it would not be cheaper to factor in a new cover every 4 years or so though....

 

I looked at getting a replacement cover, but it was about a 3-4 month lead time and almost 65-70% the cost of a new complete shelter. Now our 2 covers have given out completely, the frames would have to be dismantled to fit new covers now so the vehicles have just gone back to being sheeted up. We also put storm straps over the top (proved invaluable!) but these caused the sheet to wear through in a couple of places.

 only time will tell whether the cover is as UV stable as they say it is.

Got about 5 years out of our Machine Mart tent before the covers disintegrated. 

Pyramid nosing (which I didn't know the name of) is used extensively on ex London Transport busses (think RT, RF vintage). 

We had the issue of coolant hoses leaking in the cold on a fleet of new diesel trains in 2004. We had to change the type of clamp and the applied torque was critical. I have a friend with a vintage bus who had the same issue, and up-rating the hoses for silicone and more modern clamps (in place of jubilee clips) have cured his issues. 

On behalf of my father, I have been asked to advertise that he has (6x) new 7.50 x 20 bar grip tyres for sale, with new tubes and flaps. Price is £100 each, located near Ashford.

Steve, I would offer to buy it back at what you paid me for it, but I think you'd tell me where to go...
