[Healeys] BN1 100/4 standard build - Setting up engine timing

[warthodson at aol.com (warthodson at aol.com)]

I would suspect the rear carb. No fuel getting to 3 & 4 cylinder. Check the
float bowl to see if it is full of fuel. Check the jet setting. Is it set at
the same height as the front carb?
Is fuel able to flow from the float bowl thur the main jet into the carb? One
way to check is, with the float lid removed, fill the float bowl to the top
with fuel. Fuel should flow out the main jet. lift the piston & check to see
if fuel is flowing out the main jet.

 Hi, Can someone help me understand how to set up the timing on a standard
 BN1
 100/4 I have just re-build the engine and from the handbook cannot make out
 if
 setting the mark on the crank wheel to Top Dead Centre (TDC) includes the 6
 degrees advance or not I also would like to know how to ensure that the
 distributor is set correctly as I appear to have cylinders 1 and 2 firing
 o.k.
 but not  cylinders 3 or 4 which are sparking but not firing.

 Thanks in
 advance for any help with this matter.
