How to calibrate a carborator of shogun

Sounds like you have a fuel system problem

double check your idle air screw turns, try adjusting your main needle up or down

if its starting,its priming.....check the vent hole on the cap and see if its plugged

clogged air filter, or fouled plug, or gas lines plugged, gas filter plugged, or it needs carborator, rebuilt or throw it away

that is your fuel drain screw so if you get any water in your carb you can drain it and it was loose thats why gas drained out of it

rebuild carb using new needle and float if float is full of gas and sinking

Does sombody know where the fuse box is for my 53plate shogun sport equipe as i have no brake lights

most small lawn mowers have a carborator mounted on the gas tank.
if you take the screws out and look it has a gasket and the gasket will
be bad and need to be replaced also if it is a newwer model it has a
primer bulb that needs to be replaced at same time.

bad fuel pump. Rebuild carborator.
