Have seen various Tohatsu with choque solenoids starting issues mostly due to solenoid not maintaining paralelism with respect to plunger and plunger jamming inside solenoid when key is released.
The spring alone doesn't have sufficient back pressure to pull stucked plunger out if missaligned. Will produce unwanted flooded engine if trying to restart engine with repetitive key starts. A slight lube of plunger and related moving parts will help choke system to work trouble free.
Everybody is happy with their brand engines, constant maintenance is key, all brands have, will have tech issues, are not bullet proof.
