Alright, torque wrench for the bottom bolt is duly noted. :)
However, does misaligned float rods (ie. the floats not moving freely) really explain either the initial problem I experienced or the last one reported by the mechanic during recent test runs. That is, can they really cause major loss of power when adding power?
To recap, initial problems: Rough running and sudden, sharp RPM-drop when trying to increase RPM above approx 4500 RPM. Current problems: The same, abeit even more brutal and as early as above 3000 RPM. Doesn't this seem more like a lack of fuel than an overflow?
During the last few days, the mechanic also tried testing fuel- and airbox pressure as per the "Fuel Pressure Checking and Adjustment - 914"-video.
It turned out to be hard to measure the relative values, likely due to the engine not being able to run above 3000 RPM (and for the additional reason below). However, the absolute values were constant, around either 5 or 8 PSI depending on whether one or both fuel pumps were running. This was also not affected by running the engine or having it stopped. What gives...?
Also, strangely, he wasn't able to get any meaningful readings at all regarding airbox pressure, despite changing guages and verifying that they were working.
