I am having a hell of a time starting the engine in my 201. Recently overhauled IO-360. Normal procedure is Bob Kromer's. Throttle closed, prop forward, mixture full rich, boot on for 6-7 seconds, then off. Throttle open 1", mixture cut-off. Crank and advance mixture when firing. Doesn't work.
I have also tried the POH method of throttle closed, pitch fine, mixture cutoff. Boot pump on 5-6 seconds then off. Advance the mixture to full rich, then back to idle cut-off. (I assume this injects the pressurized fuel into the cylinders.) Same result.
The engine will usually start but only after 4-5 tries. Once started, everything is fine.
The one thing that worries me is the boost pump will only get to 15 lbs maybe of pressure. Is that low?
I attached a link to a movie of me starting it.
Does anything stand out as unusual?
