Ah I never realised that was a Hartop, Would prefer a 4 stroke though

Well, I have found some time to work on the W2 and it is now running nicely. I can confirm that the carb goes on the straight cut port and the exhaust on the tilted one. I am now working on the cooling system and the fuel tank.
Here's what it looks like in its new Sunday suit:













I'll post some more when the skids, cooling tank and fuel tank are finished

Thanks to everybody who helped me.

Has anyone got a base casting (like the one in Jims photos) please for this engine. I can give it a good home.......

Thanks,
Phillip

Found a bit more info on the W2 and W4

1/2 BHP, Bore and stroke 2.5" (57mm) 147cc

The W2 was also available air or water cooled, funnily enough known as the A2, Both engine were only sold as Castings or Fitting Kits.







Also goes to prove the N type was introduced before 1932 and believed, as the P3 which is mentioned was removed from sale in June 1928 and the P4 introduced April 1928. This would put the W2/4 as being introduced around 1928.

Cheers Steve

Also reference the small oil capacity of the W4, a sight feed oiler is mentioned for the W4.

Cheers Steve

Interesting to see what looks like some original manufacturers literature for the W2, what publication is this taken from? The W2 which started this thread is still undergoing restoration, hope it will be finished for next rally season!! Thank you for all the info. and answers, just goes to show what there is still lurking out there under benches and in sheds... Matt
