VERY impressive. Beautiful job. Was wondering it looks like the stand it's on has no ramp. Do you just pick it off when done. ERC
Hi Ace, The space between the inlet valve and piston crown was a little tight, as per the picture, the minimum clearance was 0.8mm, with no free play in the pushrod. However, I decided I would add an extra base gasket of 0.25mm, to give things a bit more room. Other options are running a slight valve clearance and / or retarding the inlet timing by a small amount. We also need to shim the long spark plug on the original plug side by a small amount, as the gap on this was closed right down as the piston was taken over TDC. The compression makes it feel like there is a brick in there when turning the engine via a spanner on the rotor nut ! [no such resistance with the plugs out, though] B.W.
