Looked like he had some kind of air-flow directing shroud over the cylinders for cooling. Hydro-lock can be an issue if allowed to sit for very long without being pulled through. If it really locks up, a pull through backward by hand will usually release it. But how to do that in this wee beastie is a bit of a puzzle. Construction of that transmission was interesting. The machinist really knew his stuff to pull that one out of his hat. I couldn't quite discern what the engine was. There was some mention of a Wright Cyclone 1830 or 1840 . It's been a long time ago - but - Jacobs radial engines were 7 cylinder R-755's, P&W's (Pratt & Whitney') were 9 cylinder R-985's and R-1340's. The next step up were 1820 series engines which - if memory serves - were twin rows of 9 cylinder in each row. Made by different companies. One big chunk of engine metal. But bigger yet were the R-3350's - four banks of 9 cylinders each - If memory serves. And I believe these were Wright Whirlwinds as well. But it has been a very long time ago that I was into it that deep and I may not have that all quite right. My memory falters. Correct me please if I am wrong, But that radial engine in that car is a very interesting sight to behold.

Oil tends to collect in the lower cylinders in a radial, can have a hydrolock issue I think. I'd add that he has a cooling problem too, no prop or other obvious airstream. > > I have seen the vid of the thing driving down the road, amazing. > > alistair > > > On 2011-11-25, at 4:56 PM, Jim Arnott wrote: > >> On Nov 25, 2011, at 8:17 AM, Alistair Bell wrote: >> >>> Aircooled and a bit bigger than 2.1 l >>> >>> :) >>> >>> http://shufti.wordpress.com/2011/11/25/ata-scrapyard-finds/ >>> >>> >> It can be done: http://youtu.be/f2V7B7-gdRA >> >> Jim > |
