I changed the primer bulb and now it's not getting


sounds like you hooked the lines up backwards, when you press the primer it is supposed to squirt gas into the tank on the return line cause what it does is draw fuel through the carb and back to the tank....filter line from tank goes to fuel pump side of carb and return line on carb goes to primer bulb then opposite line on bulb to tank...... so when you press bulb it draws fuel through filter in tank through carb and back to tank ! good luck! 2StrokeJim

My Craftsman 17cc gas weed trimmer wouldn't start.


Hi There, Check the primer bulb for tare or pin holes. Replace it. Check and clean carb jet it maybe plugged with debree. Also check for spark which you didn't say. Replace with correct plug.
Note; Do not use strong cleaners on rubber seals (O rings and gaskets) They dry up and crack.
If needed use a dabble of grease on seals

I need a routing of the fuel lines from filter to, primer-in, primer-out, to carburator, out of carburator, back to tank. this is on a poulan chainsaw, 2550. Mod 952-05138. please respond.MARRY CHRISTMAS.


There are two holes in the fuel tank, it does not matter which line goes to which hole. The lines should run as follows: One line from the tank should have a filter on it, connect this line to the primer bulb and put a mark on it with a sharpie. Another line should run from the bulb to the carb, and the last should run from the carb back into the tank. After they are all in place, pump the bulb and watch the gas in the marked line. If gas is flowing from the tank through the marked line into the bulb and on to the carb you are done. If gas is flowing towards the tank in the marked line or not at all reverse the two lines on the bulb and you're done.

No gas getting from the gas tank to the carb. replaced hoses and filter already. can not even draw gas with primer button.


You either need a new primer bulb (leaking air) or you have the fuel lines routed wrong. Here is the correct fuel line routing just in case:
Small diameter line out of fuel tank (has filter in-tank on end) connects to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then pushes any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb.If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank

Replaced gas tank and primer bulb on my Poulan Leafblower FL1500 and it appears I'm not getting gas into the carb. Any ideas as to what my be the cause?


I assume the new tank came with new fuel lines and filter in it.
First be sure you have all the lines hooked up correctly. There should be a main line from the tank ( has the fuel line on the end of it in the tank) to the fuel pump side of the carb. Then there should be a line leaving the metering side of the carb to the primer bulb then from the primer bulb returning to the tank. When you press the primer bulb you should see it **** the fuel into the carb then from the carb into the primer bulb then back into the tank.
If the fuel lines are all hooked up correctly then you should rebuild the carb.

Won't start


drain fuel tank. keep depressing the primer bulb until it is clear. drain tank again. remove carb cover and disconnect lines one at a time. keep depressing primer bulb to get rid of excess gas. remove spark plug an turn engine in a position that the spark plug inlet is facing the floor, pull starter rope a few times to get rid of gas in the engine chamber.

Put in new carb kit, starts but dies after a few seconds


If you removed the fuel lines from the primer bulb you may have reversed the lines. On two stroke engines the primer pulls gas through the carb it does not push gas into the carb. On the back of the primer bulb there are two hose barbs, one says in (in very small letters) this side goes to the carburetor and the other goes to your gas tank (it is a return line) This line is about a third to a half way up the side of your gas tank, not at the bottom where the fuel line is.

Ryobi 790r i have changed the gas line and the primer bulb . the primer will mash in 1 good time and then gets very hard to mash in . i fully choke it and it will crank but only for 3 seconds until it...


You cannot flood the engine by pushing the primer bulb too much, unless the hoses are hooked up backwards. The primer does not push gas to the carb, it sucks gas through the carb and returns it to the tank. Top barb on primer is the hose coming from the return side of the carb and the bottom fitting is the hose going to the return fitting on the tank. Look inside tank, it is the one without the filter on it, just a flange with a hole in the center.

If you can see gas and air bubbles moving through the primer and into the tank the hoses are on correctly. If you see bubbles going in the correct direction and then reversing when you remove your finger from the bulb, then the check valves in the primer may be bad. Replace primer.

When you say the primer "gets hard to mash", do you mean it is hard to push in or is it very slow to refill and return to the home position? If it is hard to push in and the bulb is full of gas and the hoses are on correctly then there must be a plug in the line going to the tank or the vent in the gas cap is not working. If it does not return, then it is most likely a plugged filter, plugged line from the tank to the carb, plugged screen inside the carb or a stuck needle valve. The primer is creating a slight vacuum to pull the gas through the carb, which is what the carb does when the engine is running. If there is a full or partial restiction on the supply circuit neither the primer nor the carb can pull enough gas for the engine to run. May need to disassemble carb and clean out any varnish, gunk or plugged ports/jets. Use spray carb cleaner. May want to think about a diaphagm and gasket kit if you do it yourself. If you do not feel confident in taking apart the carb, then take to a repair shop.
