Okay, a while back I had the #2 exhaust rocker back off while breaking in the engine.
I fixed that, and rebuilt the carbs. Tonight I reset the valve gap and, ran it for the first time. It runs, but I heard a noise I did not like. There is a leak somewhere on the 1/2 head bank. Watch this video I made. it is me cranking the engine on my test stand. No fuel or spark, only cranking. The spark plugs are in to force compression. You can hear a "fffffffft, fffffffft, ffffffffft" sound, that I don't think is supposed to be there. Link to the video on Flickr Zach |

An EX leak would have to be pretty large to be able to hear while craning. Did a ex gasket fall out by chance.
Can you hear the leak with the engine running? |
