Problem running

Hi everyone, I have this machine, is the model 393. When I step on the accelerator more than halfway, the machine decelerates and lost power. I have found that the control unit restricts the voltage in the translation coils. I suspect the wheel speed sensor. Does anyone know where he's going. Does not throw any error in the box. The throttle potentiometer and its housing are good

Understood! Thank you for your contribution, this machine has me stuck. I have changed the throttle potentiometer out of desperation and it remains the same, I have also shortened the pedal travel to make sure, but only get the engine to lose power. I have also changed the rpm sensor. I'll make sure the teeth are right, I haven't checked that. Thank you

Two things
1- check speed acquisition switch (rpm sensor ) on bell housing sitting on seat left side make sure it is plugged up and wires good and adjusted correctly and no broken teeth on flywheel
2- make sure accelerator pot isn't going past set point value

Hello, it hasn't had any overhaul or repair done in a long time. It happened to him suddenly. I do not have a diagnostic machine. I'm going to try my luck with the crankshaft sensor. The throttle potentiometer is fine
