Question: Walbro Carb

1164915

had a question on the wabro wt-366 carb that came off my old ryobi four stroke trimmer.Is fuel suppose to be pulled through the carb or pushed in to prime? I have a sepparate primmer bulb which I took the lines off and plugged directly to the in tank line (with the filter).I can immediately draw fuel as soon as the bulb is pressed so I know that the bulb and the filter are good.So I take the the line with the filter on it off of the bulb and put it on the top fitting of the carb and put a short piece of hose on the bottom fitting and then back to bulb.When the bulb is pumped no fuel is getting pulled into carb,only air. If I switch the line on the carb then the bulb gets stuck in the down possition.BTW the carb is off of the engine while doing this.Any ideas? Is it time for rebuild kit?

Hello 1164915,

Here is a short answer to a long question. I do think it is time for a K10-WAT Repair Kit.

Question: Ryobi 975r Fuel Lines

I've looked through the list of available parts for the 975r trimmer. The only thing I see there is a return line. I'm looking for all three of the fuel lines. Does this include all three?

Question: Gas Lines

Bill Lupien

I have a Ryobi 975r trimmer and I got new gas lines but can't figure out which line goes where. There are three lines: two go between the gas tank and somewhere, two attach to the primer, one for sucking gas in the other for blowing out. Then two go into the carburetor. Can you tell me which lines go to where? Thanks
