Hi, I’ll try and make this not sound too confusing.. Last week I was using my Ryobi 2 Stroke petrol strimmer, Everything was working fine with it, started fine, ran fine ect… The day after i went to use it again and noticed when i primed it, the bulb would not fill up with fuel, only a little bit and just small bubbles. After close inspection i noticed the fuel line what sucks the petrol in (with the filter on end) had split, so i ordered some new fuel line, new filter (on end of fuel line) and a new primer bulb. Fitted it all but still had the same problem. So next thing i thought maybe the carb is blocked somewhere so i removed the carb gave it a full clean from top to bottom, refitted and still same, the primer bulb would not fill. So i ordered a rebuild kit for the carb. Rebuilt it by following a video on youtube. Refitted the carb, still no luck. As i was trying to prime it, my friend noticed quite a lot of fuel dripping from the bottom so after close inspection i noticed the new fuel line i fitted, the fuel was leaking over the top and realized when i pulled it off the carb it came off too easy (and also went back on too easy) not really much give so im not wondering if this could be the problem??? I have tried everything and just cannot get to the bottom of this hope somebody can help me . Oh by the way, I noticed aswell (for some strange reason) when i loosend the right screw which holds the primer bulb in the fuel came into the bulb really fast but when primed it was leaking also sometimes when the bulb was pressed it didnt come back up (until i loosend that screw). Strange
Since the new fuel line pulls off and goes back on too easily, it sounds like it’s the wrong size fuel line (too big). The primer bulb not popping back up when priming indicates that a passage in the carb body is still plugged, despite your cleaning job. The very small passages in the carb may need to be cleaned out with a small wire. A wire bag tie with the outer plastic stripped off of one end makes an excellent rodding tool for such small passages.I’m presuming that you replaced that primer bulb when you worked on the carb, but if you didn’t and the bulb is a brownish color and kind of stiff when you pump it, it needs replacing also. An old primer bulb that has gotten stiff and brown due to exposure to the gas and oil in it can also refuse to pop back out properly.
The fuel line goes back and forth which surely makes a noise. I think the portable generators body is plugged thats why its doing this way.
