Briggs and stratton classic engine

I think you need to be very accurate when setting valve clearances or the decompressor doesn't work. If in doubt aim for the smallest clearance of the acceptable range e.g. if it is 4 to 6 thou aim for 4 thou.

The decompressor lobe should be spring loaded to hold it in place while starting and will rotate out of the way once the engine gets going through the wonders of centripetal force. You can find YouTube videos showing you how it works. 

Climate Change?

Posted: 29/11/2016 at 13:54

The northward march of the growing range of champagne grapes is one possible benefit for the UK of climate change at the expense of the Champagne region. The big champagne houses are buying up land here in West Sussex and local growers have been making some very fine sparkling wines for a few decades now. I still have a couple of bottles of 1992 Nyetimber tucked away as well as vintages from another half dozen vinyards :)


When someone mentions a few very rich people getting even richer I immediately think of the Koch brothers, major oil business funders of self-described climate sceptics. While increased atmospheric CO2 can be beneficial for crop growth unfortunately the same cannot said for the ocean which will rapidly become acidified and have a major effect on the food supply of half of the planet.

mould on my grapevines

Posted: 29/11/2016 at 13:39

Sounds like botrytis (grey mould). Bordeaux mixture is only really of any use as a preventative for this and doesn't treat infected plants so might not be much use. One fungicide which I think are still available include systhane but that may depend on where you live, it isn't easy to get Merlot to fruit well in the UK so I'm guessing elsewhere? I would clean up the vines as much as possible over the winter to remove any source of spores as a first step.

Can redwoods survive without winter?

In nature they will survive hotter summers and colder winters than your range of temperatures. I would leave them outside on the balconey, they are not indoor plants. Out of curiosity, what are you going to do with them in the future?

Monday's Supermoon

Warning, here comes the science bit!


The trick to taking moon photos is called Lunny 11. It is a variation of the old Sunny 16 rule for daytime photography. Those of you old enough to have used film may remember the guide to exposure printed on the inside of the box which is based on Sunny 16. Basically it tells you how to use manual camera settings to get a good exposure.


On a bright sunny day if you were using film with a speed of ISO 100 then you set a shutter speed of 1/ISO i.e. 1/100th sec and an aperture of f16. Now the Moon is a rock in bright sunlight but the light it reflects has to travel a long way to get to us and some gets lost so we need a little more exposure for Moon shots. So instead of f16 we use the next brighter aperture of f11.


You can substitute other shutter speed/aperture combination to get the same exposure e.g. every time you double the exposure speed you need to open up the aperture to the next smallest number 1/200 and f8, 1/400 and f5.6 etc.


Those settings are a good starting point to get a good exposure of the Moon. If you just use the auto mode on your camera it is likely to get it wrong as the scene it sees is mainly black with a small bright bit. It tries to make the black bit lighter but then makes the bright bit too bright.

Camera Talk

Verdun, the Sony A500 would now be considered an antique in the digital world as it was introduced about 7 years ago. I would be surprised to see it still offered for sale new today unless it was very cheap old stock being cleared out. It will certainly take decent photos and will be more than good enough for most people's needs though. There is also another Sony, the A5000 which is a current model. It is a different design of camera from the A500 so isn't just an updated version of the older model.

Hazelnut butter! Shell them, roast in the oven for about 15 minutes then blitz them in a food processor until they turn into nut butter. Can take anything between 5 and 15 minutes to get to the right consistency.

Any one Any Painfull Gardening Memories

Posted: 29/10/2016 at 01:28

Simple scratches from removing brambles resulted in blood poisoning. 3 doctors, 3 courses of antibiotics (2 of each quite useless) over 9 weeks to get under control. Lower legs and feet badly swollen unable to wear shoes, face like a Dali melted clock with a matching impact on general health. It is a jungle out there, be careful! 

Montbretia

Posted: 24/10/2016 at 22:56

The RHS use both names for all cultivars so it is not surprising that there is confusion. The troublesome montbretia is a hybrid, crocosmia x crocosmiiflora. It is an offense under the Wildlife and Countryside Act 1981 to plant or otherwise allow it to grow in the wild so it must be disposed of appropriately. 


I have it in my garden and find it easy enough to keep under control.
