Ficht 1200 starting issue

[Paul2005GPR]

Just had emm rebuilt. New fuel line restrictor as the factory one fell out, drained and refilled with new gas, will crank and crank and not start but if you shoot a little fuel in the tb throats, it will start and run fine until you shut it off....also it will only die with the tether, start/stop won't shut it off...need advice.

Which year and model is this machine?

The LR-503 Start/Stop module controls engine stop using the push button, so the LR module is suspect.

What new fuel line restrictor did you use?

Not starting unless primed with gasoline is typically an indication of weak voltage at the fuel injectors during cranking. The most common cause is the EMM needs repair, but sometimes it is the stator coils or the flywheel magnets.

You can ohm test the Ficht stator coils. All five coils should have similar ohms, these are very low ohms numbers with two of the coils being slightly different from the other three. All five stator coils should have no connection at all to engine ground.

It will start on its own if I turn my booster charger all the way up...new battery?

My guess is that the EMM or the stator has issues. Cranking it with excessive battery voltage (how high are you pushing it?) makes it crank faster than normal so the magneto voltage outputs are higher than normal, enough to get it to light off, it appears.

Hmm, just had the emm rebuilt, when cranking with the charger, the dash says like 18v this is ramping up my voltage and letting it start, the battery in it is junk so I will get a new battery and then test the stator output..
