            Hi everyone<br>
            <br>
            <br>
                                 My friend Bob and I have his rebuilt
            engine back in <br>
            and running after its crankshaft failure. It is currently
            89MM bore with <br>
            a DWR1 camshaft similar to the 100M Cam specs. The head is a
            previously <br>
            installed Denis Welch aluminum head that we has to mill
            slightly because <br>
            the crank failure allowed the #4 piston to hit the head. The
            valves were <br>
            ok.  During the break in period we have the timing set to 8
            degrees <br>
            advance at idle.  Bad me I don't know what the advance is at
            3000 rpm <br>
            with the Mallory distributor. We plan to check it this week
            and keep the <br>
            advance to around 35 degrees total advance. The engine is
            running great <br>
            with 8 degrees advance at idle, backing it off to 6 degrees
            the engine <br>
            was not as happy. Using 93 octane gas with 10% alcohol. 
            Ethanol free <br>
            gas is available near our house in Maryland but not here in
            CT.<br>
