Hi Reuben. Thank you for the reading. You are telling me that the reading is not getting to 250 when the rpm is at 5Krpm. This is all I needed to know. No mater what other start motor or o-ring problems there may be, the ecu will never try to start the engine after this first sensor test if the reading is not at least 250. I will repeat again - The ecu is not getting enough signal from the sensor which could be caused by the sensor or the magnet . The sensor or the magnet is marginal. You are not getting quite enough signal. The reason you smell gas is that I do a short purge of the gas solenoid during the first runup test to get rid of liquid in the lines from re-filling. The ignition does not start until after this first runup test and the rpm has read 5k rpm and the sensor signal level is at least 250. If these tests fail the, the ecu will not proceed with the start up sequence with gas and glow power and will display the no rpm error, low rpm error, or sensor low error. Any error associated with the conditions that keep you from start up such as battery low, plug open, set throttle low etc are displayed on the main screen either in the receiver mode or the manual mode. The errors that occur during startup or running after the start sequence is started wil be displayed in the third main menu where you get at the teach and parms menues.

I can fix the problem by changing two resistors in the ecu to increase the gain of the sensor amplifier if you send me your ecu's. Later. Bob.
