Question: 720r Primer Bulb

gwd54

I need to replace the primer tubes on my trimmer, and to verify the hookup to the primer bulb: the bulb should suck fuel though the carb and push it into the tank, correct? I have a starting/idle problem, and I think it is from the air leak at the primer tubes.

Thanks.

You are correct. The fuel should be pulled through the carb and then back into the tank. We have an article and video that shows how to determine the proper routing. You can find it at the following link...

I hope this helps,
