i would like to know what the fireing order is on a hercules ixb3 engine is i know it goes 1243 but is that from the back to the front are from the front to the back and what it is if the distrutor was in the engine and where number one would be on the distrutor.
IX hercules firing order is 1243 ,#1 is at the front of the engine ,as far as i know all hg's and oc3 crawlers came with a magneto and if it was installed correctly #1 is at the top right on the cap. there is also a timing mark on the flywheel ,remove the pipe plug from the bell housing on the right side of the engine but the flywheel can be installed in two positions either right or 180 deg. out for #1,if you have a dist. just get #1 on tdc of compression stroke and see if it lines up with one of the poles on your cap if not turn it until it lines up with a pole and use that as #1 and install the rest in correct firing order.
happy holidays ,walter
