Dry husqvarna 455 rancher

Recommended Posts

My husquvarna 455 rancher stopped working and looked like it wasn't feeding fuel properly but still getting compression. I replaced the carb with a new one and when I prime it fuel (and some bubbles) come through but it doesn't start and the plug is bone dry when I pull it.

 

Suggestions on where to go from here? Had it apart a couple of evenings and getting a little frustrated!

 

Cheers

If the carb was a brand new factory one, the issues could be: -

 

1) Choke not engaging correctly.

2) No secondary compression (top of cylinder)

3) No Primary Compression (no vacuum in the bottom end crank cases)

4) Blocked fuel filter

5) Impulse line faulty/blocked

6) Split/Damaged fuel line
