Introduction
Use this guide to replace a broken or worn-down pull start rope from a Stihl BG 50 gas-powered leaf blower.
The purpose of the pull start rope is to start the combustion engine. The rope can become brittle if it is not used frequently or it may begin to tear after extensive use. If the rope is only dirty it is not necessary to replace it. If the rope has already broken, Step 2 can be skipped.
Be sure to removing the fuel from the blower’s fuel tank to prevent a fire hazard.
The old rope should be disposed of, but the pull start handle can be kept as a spare part.

My cord works fine after disassembling fron blower. Put it back together and pulls a little way; then gets stuck, pull more rope,.but I can’t pull all the way out at one time to start the blower. Is there a problem with the wheel or motor
Cord on blower won’t pull all the way out to start engine on big 50. Took it apart and pull rope pulls fine. Reassembled it and rope won’t pull all the way out to start.
What size rope? 3mm? 3.5mm?
