Are there any other builders of the Red Wing engine nearing completion ? My cam is same shape as the plan . It opens the exhaust valve at the right time but it wont hold the valve as long as the plan tells me . It should stay open nearly to TDC . Mine closes about half way up the stroke

I am making a new cam with longer opening time to try , but I just wondered if I was going wrong some where

Regards Phi

RCDon used a flatter topped cam rather than the more rounded one that is on my set of drawings
