One minute the Pollies say there will be no more restrictions which usually means that very soon there will be some bought back. We dont mind wearing a mask when in shopping centres and places like that where there are many people close together. But out in the parks we are less strict on ourselves and as odd as it sounds we do ask if some of our visitors have been in hot spots and a relative recently back from Singapore has been Covid tested evry 3rd day and all clear.
It does come to a stage where we must take charge of our own health and since we retire next month we want to travell a lot with our caravan so will be even more careful the places we visit.

Aussies initially got the astra zennica as the first and most popular option then came the Pfizer followed by the Moderna. We got the AZ x2 and are booked in for the booster next February which will be Moderna.
Yep the new "Irish version as I call it" the O'Micron is far more contagious  but far less harmful. Very few needs for hospital and even far less deaths. It is at the moment being trated like a bad cold so we are told not o worry as much. Now being old now days we still wear a mask when out at the shops etc so should be good. Also living in Rural area also reduces the risks.

Thank you for your kind thoughts and no doubt all member and guests here wish you and your Family and friends a happy and safe Festive Season.
We will be stayi ng at home but my eldest Sister is comming up for the day which is always a great time together. Yes kids, grand kids and now up 3 great grandkids all live away so wil not see them at all this year but as we are retiring early next year we will go north and cross the border to annoy them as that is what we call 'getting even'.
Yes, the new variant of Covid is spreading like wild fire here in Australia and it is Summer here when everyone is mostly out doors but the younger population go out to the clubs and bars and it just explodes the numbers. Fortunately Australia is around 95% vaccinated with booster shots being offered up and we will be getting our boosters next month. So it may well be the case of masks and signing in and out of shops and places to try and manage it better. There has not been many reports of deaths due to this latest Covid but there has been one or two that I am aware of.

Stay safe everyone and always keep an eye out for your next project.
Merry Christmas from Cobba & Cobbarette.

Beautiful job on your ship. With your "O" rings use a vernier caliper to measure the diameter of the inside of the groove on your liner, the width of the groove and then the inside diameter of the engine block. These are the 3 critical measurements to get the correct size "O" rings. Write them all down in metric and imperial sizes but being UK made is most likely imperial sizes only.
I live in rural NSW Australia and our local small town has a bearing shop that also sells "O" rings and he has always been able to supply me with the right size "O" rings so yes shop about. Even if need be do some online shopping in a larger city near you.
Without a doubt having the head gaskets made professionally will be far more reliable than knocking some out of possibly the wrong material yourself. It may cost a little bit but for the peace of mind it will be worth it. On some restorations I have done I think of all the work that had been done to get to this point and to take a short cut or skimp on using the proper part and then have to redo the job again in 12 months never appeals to me and is false economy. So I can only suggest have them made.
The paper gasket in your picture was not badly constructed and I cannot see any imperfections in it so why was it removed? Was it just to inspect the general condition of the engine?

 Now when you do reassemble the heads onto the engine I always use a head gasket sealant. This can cause some hot debate as we all have our own ways of doing things. 50 years ago they use to use Silver Frost paint but this was the original style that had aluminium specs floating around in the can and it did seem to take up any small imperfections. Now days I use a copper spray made by may companies and it is sticky as well and any excess wipes off with a petrol rag. When I have been in a pinch and doing a lawn mower engine and no new gasket available and I was off to a Rally I reused the gasket with the spray. This was around 9 - 10 years ago and it is still working. At the same time when I sis my David Brown Cropmaster style 30C tractor engine up totally, even though all surfaces were machined I still used the head gasket spray.

Hi Peter and Welcome to the Forum.
What part of the world are you in so that members can direct you in the right way. Here Australia there are many places to supply gasket material even make them for you quite cheaply as many of the old engines already have been copied depending on the exact model. Sometimes a sample one may need to be supplied but I understand you would like to make your own. Someone will be along hopefully with the right thickness paper to buy. Some head gasket paper comes with metal in the middle for the heat. Are the originals just a paper gasket or not?
 If you say the old ones come in at around 3mm then you will need at least 4mm thick new. As for the "O" rings, a local bearing shop will be able to put as many on the counter top as needed. This is something that is readily available. By taking a liner with you they can measure the size of the groove to get the thickness right and then measure the diameter of the liner and again get that right. Discourage them from supplying metric size "O" rings as they should be Imperial.

WOW, 150 quid? I thought that Ned Kelly, our infamous Bush Ranger only was still thieving from us here in Australia. He must have relatives nearby to you.
I can understand what you saying. There are members on this Forum who can help you out but not all of them log in on a regular basis. Hopefully one will do so very soon and help you out.

Hi Robert and welcome to the Forum. Sorry I cannot answer your question but soon enough someone will be able to give you the answer you need.
Since you are aware you need to buy spares maybe that supplier may be able to help you straight away or if you ever need to do the engine swap transfer those parts from the original engine to the new one.
I had the pleasure to spend a few nights on a narrow boat when I visited England many years ago and it was one of the highlights of the trip.

Very interesting story scalyback. I was not aware of those details so it would be a very rare engine if one ever turned up here in Oz.

I tend to remember similar info for the Lister engines. Do a search of the forum in this section and see what turns up or a Google search for the same info. There are members on this forum that can help you for certain but not all visit on a regular basis so it helps to have patience.

I also meant to say to not use synthetic oils on these old girls, they are not designed for it.

Hi mate and welcome to the Forum.
Sounds like a nice toy, I have a Liner Roughrider dumpy with a twin SR2 Lister in it.
You are right about the oils and changing them, I have usually also flushed the gearbox and diff out using diesel fuel and driving it on rough road or up and down some hills then drain and fill with nice clean fresh oil. Here in Australia I use straight SAE30 oil and I believe that is good for you but maybe a bit heavy during winter time. The only issue would be harder starting because of thick oil but on a single I think you will be fine. Dont forget to do the air filter as well. Not sure if you have done so already but I would drop any old fuel out and start with fresh stuff.
I am not familiar with the Petter diesel but someone will confirm if there is a cold start position on your engine as there is on the Lister. Go around and adjust your brakes and that means the hand brake as well. Grease the dumpy from front to back as this will make your steering a bit lighter as well after doing the king pins and tie rod ends even the centre pivot bush will need a good feed of grease.
As for dating your dumpy someone will be able to help from your serial number also if you could post the HP which will be listed on the engine itself if not the build plate if it is still there. They are a heap of fun to own and I fitted an extra seat for the missus to get on so we both can have fun together.

Hi again Paul, I just had a quick look further up the page and this Forum has a dedicated Generator section and the second thread on the current page is discussing a H series Lister with generator.
While waiting for some help here maybe have a quick look through that section and see if there is any help. There is another generator thread running in the  Engines section but he has a different problem but is receiving help help 2 members who may be able to help you out as well. Have a read there and send these guys a PM and ask if they can help you too.

Thank you for your very kind wordss but there would be no way I could have done it with out the enormous help from members on a welders forum who knew wha to look for and there for they guided me through the repair.
Yes, my electric soldering iron was like using a sledge hammer on a thumb tack but with persistence I got there.
The capacitor measured 2-3mm in length and close to 1mm in width. So small I 'borrowed' Dees tweezers from her sewing machine to place and hold it while I put a tack on one end.
I only had a go at what I was advised to do by people who have the 'smarts like you' on what to look for and do. I am proud that I actully did it but I do not understand what it is I did as electronics seem to avoid my b rain pettern and wont stay and allow me to understand them. As to have the ability to reverse engineer circuitry, now that is a true talent and IO tip my hat to those who can.
