Subject: Re: 2L engine problem
Unfortunately I have had no more reactions with advise how to cure the problem. However, I have discovered that the engine has rather unusual camshafts with very flat cams which means that the valves stay open longer. This could very well be the reason for the petrol "spit-back" problem. I am now replacing them with new camshafts supplied by the club - they are quite diffrent in shape with much more rounded lobes. I expect that this will take care of the problem.
As for downdraft carburetter inlet manifolds - they were done by Maniflow in Salisbury - tel. 01722 335378. They know exactly how to make them and often work with Burlen (carburetter manufacturers).
