There is no gap as they use the flat plug that does not have an adjustable ground electrode. If it is older 35 thousandths will do the trick

Usually, replace the recoil spring. You also, may be able to increase the wrap tension by: 1) pull spark plug (easier to manipulate spinning the motor) 2) wrap the extra loop of rope around the start pulley gear. sometimes there is a bracket, etc. to work around

Sounds like you need marine grease in the bracket.. Should be like 6 or 7 grease ******* around there. They need regular greasing

Probably the pump but could be a vacuum leak
