SOURCE: replaced new gas line, new primer bulb, new

Line from tank with the filter on it is the supply line and goes to the carb inlet fitting. This is typically on the "bottom" of the carb (with the tank being up) and will usually have a fitting with barbs or a bulge on it to ensure a tight fit. The other fitting on the carb is the return line and is usually a straight tube fitting with no barbs. That line goes the suction side of the primer bulb. The third line goes from the outlet of the primer bulb to the return barb fitting in the bottom of the tank. Fittings have to be removed from tank to properly install the new hoses on them. Remove retainer ring on outide of tank and push fittings into tank, then shake out of the fill opening. More details on replacing hoses are listed in another post about Repairing Ryobi trimmer.

Have you checked the spark plug?

SOURCE: PRIMER BULB WONT **** FUEL INTO BULB. NO HOLE IN

Run a small paperclip into the fitting that the fuel line is attached to on the back of the primer bulb and make sure it is clean. Then go to the other end of the equation and make sure that the fitting is cleaned out on the carb where the fuel line attaches. Hope this helps and good luck.

SOURCE: Primer button on homelite gas trimmer

It's possibly the filter, can't help there. I would check for a split line or loose connection between the tank and bulb and even splits in the bulb itself.

SOURCE: 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

Car wont start when hot


Well, if it is getting too hot then you are looking in the wrong area. I would check the water pump and the thermostat. Thermostat first, it is cheap and easy to fix.

My Echo SHC-212 will start and slow idle but when I give it gas it boggs and stalls. I've changed the spark plug and I'm using the proper mix. Any suggestions? I was thinking of trying to clean the carb...


The prior posters must be from the Briggs & Stratton era :0] This is an EPA carb. You can only adjust the idle speed. The Echo SHC-212 uses the Zama RB-K75 carb.

My SHC-212 had the same bogg/stall symptoms. I had to disassemble and clean the carb to get rid of it. There is an internal filter screen that sometimes clogs. I soak and use compressed air to blow out all orifices. But the real problem is leaving ethanol gas in the carb during storage. It warps the delicate gaskets/valves. So buy Zama rebuild kit.

Need A parts diagram for a Sthil G65 Blower carb.


Unfortunately, Stihl won't release any of their illustrated parts diagrams to anyone except Stihl dealers. The dealers won't release them either. It is possible that the manufacturer of the carb will have a breakdown listed on their site. Stihl primarily uses either zama carbs (www.zamacarb.com) or Walbro carbs (www.walbro.com). Look on the carb for engraved numbers and letters to let you know what series and model to search on. The manufacturer is usually listed either on the bottom diaphragm plate or up on top. Walbro series usually start with a WT, or WA. Zama will usually have a C series (ex. C1U)

Good luck!

My weedeater lawn edger wont start. I get no gas in the primer bulb, but has fuel in both the main line and the return line. I blew out the fuel fliter and both lines but still no fuel in the primer...


There may be a malfunction in the check valves in the primer base assembly. Before attempting to get a new assembly, take the retaining screws at the bulb off, remove the bulb and spray the assembly liberally with WD-40 or an equivalent light lubricant. Sometimes this will free the check valves as they only let fuel flow one way and there are 2 of them in the primer base.
Do not use strong solvents, do not ever soak, and never use high PSI compressed air on these carbs. Sometimes, when the check valves in the primer base go bad, the carb floods and the reason is unclear. Zama doesn't list this as a reason for their carbs flooding, but they can. You may wish to view a parts breakdown list for your specific carb. You will need to know the type (stamped in side of carb body) and the model (stenciled in side of carb body). It will be something like a C1U type and a W-18A mode...thus its a C1U-W18A Zama carb. Here is a link to get you started.

Parts number


You need to know if it is a walbro or a zama carb. to start with.
then look closely at the carb. and find #`s
very small

walbro will be wt or wa then some #`s
zama will be c1q or c1u and some #`s on the opposite side of carb.
Walbro will be on the same side

you need to know the carb. #`s so a kit can be found for that particular carb. IE: complete kit or diaphram kit
