What do you know about air bleed holes in those 'hockey stick' inlet pipes?
A guy in Another Place says that there are holes on both sides to allow excess petrol to drain out if they were flooded on startup.
Seems a bit weird to me, but might explain some of the strange attributes that these engines seem to have.

Peter,
As far as I can remember the manifolds had small holes at the base of the tubes just before they attached to the heads. Also they arte strictly petrol engines, I think you have two tanks because they are thirsty lumps off load so two tanks extended the running time. I have an article from SE you can copy when I see you at the end of the week.
Thanks for confirming that, Martin. Let me have the SEM issue number, I can look it up in my own back numbers.
Kim's email is bouncing, in case anyone is trying to contact him.

Not something I've seen on an SE before but I can think of a couple of car engines that had manifold drains - Hillman Imp with a little tube and (I think) the ubiquitous Ford Eight and Ten with grooves on the gasket face.

Austin and Bedford also used them at various times, but the volume of air was probably higher so not so much affect on the carburetion if they blocked up.

Interesting pics, Peter. I discover that the nicely trolley mounted, flat belt pulley equipped "1930's" 110 Volt dynamo with control box that I bought a while ago to load the Crossley 1075 is exactly the same as the one on your PU8, dials, fuses, knife switch 'n all. :o))
I too would be interested in the SEM issue number.
My box only had 22 mails in it this morning, & was cleared late Friday evening. Should be OK.

Hi Kim:
Goes to show, the genny bit was probably more viable than the PU8.
April 1984 was the issue, Martin P kindly advised me, quite an interesting article, note that the picture of the engine with the compressor shows the earlier engine with the inlet pipes coming out of the crankcase.
I added two more pictures yesterday, one of the magneto and one of the carb, and what looks like a breather pipe to the crankcase.
The email bounced, no detailed reason, not a problem.

I am trying to sell my PU8 if anyone is interested, Has not been started for about 4 years but was a good runner last time i tried it. Yours for =A350, Derby and Burton on Trent area. Email pswindell at googlemail.com if interested.
Thanks Paul.
Hi Paul:
Do you know the serial number?
Is it just an engine on the floor or in a frame, whatever? Peter
