RE: HIGH SPEED TURN OFF ?
If your jets are REALLY clogged like mine were, you could buy the paint bucket full of carb cleaner and let em soak. It comes with a handy dip basket, too. Too bad I (or the wife or kids)lost the $80.00O-ring and filter set,and didn't realize it till I tore down and soaked the 1st carb. I really wanted to do these 1 at a time so I can get em back together. 
But the O-rings have to get passports.
Good luck,

RE: HIGH SPEED TURN OFF ?
Sounds like the same symptoms I had with my 92F. Engine dies after an extended period at high revs. It was fuel starvation, and I found that the vacuum tube from the #1 carb inlet manifold to the Fuel valve was kinked and the Petcock was not opening fully. Took the outer PVC sleeve off the vacuum tube and found the restriction was caused by the glue that holds the outer sleeve to the vacuum tube where it passed through the retaining fitting on the carb. Removed the outer sleeve, straightened the path of the tube up a bit and now she's as good as gold. Will replace the PVC sleeve with a wire coil sleeve at some stage.

If it won't run unless the choke is on, it usually is the the pilot jet in the carbs (the smallest ones= easiest to clog). I my exper. you have to pull the carbs, clean the pilots (and the rest of the carb while your there). I use a single strand of wire and lots of carb cleaner and some comp. air. Auto carb/fuel injectorcleanerfuel additiveswon't work and could distort some of the plastic parts in the carb which is a nightmare. I am a big believer in Stabil for any lenght of storage.

Removing and cleaning the carbs is a let easier than it sounds. Just get a Hynes Manual and follow the easy step by step. I used CRC Carb cleaner to clean carbs inside/out and the pressure of the cleaner through a spray tube attached to the CRC nozzle was sufficient to do the job. Just don't rush it and don't lose any parts!
