standard mechanical fuel pump (new); replaced ignition pack (called em points - sorry), vacuum steady around 17". Last test showed steady coil voltage supply also. Last test seems to be getting worse with noticeable fluctuations (40-60) in oil pressure with slight rpm change, more than normal. wouldn't run steady at ~ 1000rpm and had a carb backfire as well. Think it might be time to think about removing cab and pulling engine.
