Walbro Carb Fuel Lines
I just finished converting a Stihl 31cc trimmer engine with a new electronic ignition and a Walbro WT433 carb. The new carb has two fuel inlet lines and I'm assuming the larger line is the main fuel inlet and the smaller tube is for the bulb primer. I need some help with the fuel line hook-up. Where does the primer bulb hook up and what does the smaller fuel line do??? It's a shame I didn't notice the set-up before I took things apart. Thanks for any ideas.
