Echo SRM 225 starting problem/ fuel leak?

[Doug41]

Im new to this forum and DIY repairs. My echo srm225 has run great for years. Finally put in a new carb a couple yrs ago and all well until recently. Now very hard starting and fuel leaking out spark arrestor. The arrestor is very clean? Any ideas? “Another” carb. Any help appreciated.

If you didn’t use an OEM carb, but purchased one off the web, than could be the problem. Before replacing try this. When you see the leak, set the unit down on concrete and loosen the gas cap. If it stops leaking, I’m guessing your tank vent is plugged.
