855375 2010-02-05 00:30:00 :clap :lol: You crack me up Mets :lol:

For awhile there I thought you were stuck on being serious, considerate and all that, seeing that you have a Phil Goff brand of bike. :banana
BTW, you going to the ACC parliament ride on the 16th?

855376 2010-02-05 01:01:00 Lmao.

Last message I got from the orginiser was this


**** you ******* I aint joking, so take ya funny **** elsewhere moron.

I guess that means me and him ain't friends, and he doesn't have the best sense of humour.

855377 2010-02-05 08:54:00 I've got an old hoe with a B&S engine, and I find it amazing how this seldom used old beast fires consistently on the second pull.
They sure know their engines. I wish they'd build Operating Sytems as well as Briggs built engines.

855378 2010-02-06 02:39:00 One more comment about our Briggs and Straton mower from the Warehouse: It cuts through tall wet grass no problem at all. It cannot be the most powerful motor but it does just fine, and the hard plastic catcher holds more grass than some of the fabric catchers I have seen.



Lmao.

Now its my turn to LMAO. Ever think of being a stand up comedian? Reckon you could make some decent $$. Really. You already have a :rolleyes: PF1 fan club. If not a stand up comedian - which probably means you would have to do your stuff in AKL or at least Wgtn - then go online like Pat Condell on Youtube. Won't make $$ online but it could lead to a big NYC gig and BTW this means you owe me a few beers when you go pro and get famous and all that. :D Yeah and I know your next comment will be to trash this idea but it will be #@#X'n funny as usual. :lol: And I think your good woman will like the idea of getting you up to AKL - and out of the house...:clap

855379 2010-02-06 02:46:00 The problem is takes me two beers to get going, I'm at my best at around beer 4 to 8, and then its rapidly downhill to a career ending round of disgraceful shenanigans as I plow through another dozen or so beers.

So by my calculations, based on the rate I drink beer, My career would start, peak, and crash in under two hours.

855380 2010-02-06 03:21:00 Interesting that modern car oils should not be used. Why? Have a look at the bottom of this B&S page (www.briggsandstratton.com) and you will see that multigrade oils can be used. There may be a reason why non-car oil should be used but my feeling is that when a manufacturer says to only use their brand of oil it is a way of getting more $$ out of a customer.

BTW, I may be unusual in that I have always changed motor mower oil twice a year. It is so easy to do and the amount of oil needed is small.
Multigrade oils are relatively thin when cold, and relatively thick when hot. This is one of the reasons modern car engines last so long.
Air cooled engines run pretty hot in some places, so they have to have large clearances when cold to allow things to move, the clearances become more conventional when hot due to expansion. (OK, forget the el cheapo big end here.) These big clearances mean that at start up the oil must be quite thick to take up the slack in the piston, and the end gaps in the piston rings. When the engine heats up it needs thinner oil to cut down the oil drag in the now closer fits. Multi-grade oil does not excel at this. Also, the temperature in the piston and on the cylinder walls are higher than liquid cooled engines, so some of the car oil additives are operating outside their comfort zone. Old style engines need old style oils and fuel; the B&S engine is pretty old tech. It is still amazingly good value for the price, and if you knew what mower manufacturers pay B&S for them, you would be astonished.
Frequent oil changes are not all that astonishing, especially among those who think long life is not unusual for these little beasts.

855381 2010-02-06 03:35:00 ...Also, the old 'straight' mineral oils were good at forming varnishes on the bearing surfaces, and also had greater 'lubricity' whereas 'modern' oils have detergents to keep systems clean.

When Shell X100 detergent oil first appeared in the early 60s, engines were siezing up everywhere due to varnish being cleaned off the surfaces and the systems being filled with the years of accumulated gunk.

Aluminium big ends are rotten bearing materials, having no 'embedabilty' for particles, so they are relying on hydrodynamic fluid film to prevent metal to metal contact whilst running, with varnish and hardness of the crankshaft to help prevent pick-up during start-stop when the surfaces are rubbing.

Royal Enfield tried to be clever with alloy big ends/conrods, with their Constellation, which was prone to conrod failure in a big way.

855383 2010-02-06 04:44:00 A bit like piston engined planes. Most use Lycoming or Continental brand motors either 4,6 or 8 cylinder horizontally opposed engines which have been around since WW2 as far as I know. Not much has changed in the design of them.
