Hi OF,
Well some did and some didn't. This was primarily as an option so that regardless of what the engine was fitted to it could be more easily emptied. Quite a few Briggs engines have this and if I'm correct all the latest sloper engines that Briggs make have this option fitted as standard. In regards to the oil entry facility if you look at the earlier engines they were all cast with the ability to have the fill point on either side, but generally they were just machined out on one standard side but some are getting it machines on both sides.
As far as those primer bulbs on the Kirby engines are concerned they are a bit of a waste of time as Kirby's usually start first or second pull once the petrol tap is placed in the open position.
Mens Shed............mmmmmmmmmmm. I think we're way past making wooden rockin' horses here and there's far more knowledge here than a mens shed that's for sure.
Gadge, sorry about the delay in answering 45 stuff, but I've been in hospitals with my 7 year old daughter that's broken her ankle and now has it in plaster. Crutches and 7 year olds don't play well together I might add.
Cheers,
BB.
