B29 Valve Lifter
« on: 02 Feb 2020 at 01:28 »
Does anyone have a spare valve lifter assembly for the B29?  Or some photos or drawings showing the parts?  I got the B29 running and it would be great to have the valve lifter available to stop the engine rather than stall it out after a run.

Thanks

I do not have any info on the B29 (or the 350cc sump models), but this is what the exhaust valve lifter loosks like in the 350EW and the A31 model, that bracket the B29. See this post here:

However the oil pump drive of the B29 might have forced them to do something slightly different.

Thanks Doug, would you happen to have any drawings of the parts, from what I can tell, they may work for the B29, it looks like the oil pump would only be in the way of installing the lifter parts.

I do. PM me an email address that you would like the drawing files (PDF) sent to.
