Installed a 3/8" drain line from the air box near the carburetor air inlet to drain excess fuel in case fuel comes out of the carburetor due to some unforseen situation. The drain exits close to the crancase vent exit.
Removed the left side intake manifold from the cylinder head manifold to check for some reason why the the #2 cyl runs lean. Found nothing amiss. The intake tube feeding the cyl head manifold does angle toward the rear (#2 cyl). I inserted an 0.032" aluminum sheet into the rear of the tube to straighten the angle so it does not point toward the #2 cylinder. Another engine test run will show if there is any difference in the cyl #2 mixture.
Intake tube angled toward cyl #2
Divider inserted in intake tube to divert air from cyl #2
