There is only one gasket, Jenny. To figure ouut which way it goes, first put it onto the carby, then transfer it to the motor. Next put on the carby, and tighten the screws. Then hook up the electrical wiring and the fuel lines, and the job's done.

Husqvarna 25r - is this a good model?

The 25R was a badged engineered machine ( not made by Husqvarna ) the first model was a Mitsubushi engine, the later version was a Mariama, both were good machines in there day, they were offered with a line head and a grass blade, they were as you can guess approximatly 25cc, the early version had points condensor ignition, and later on had electronic, parts are now becoming hard to get, so be aware.

I need a operating manual for a Husqvarna 25r weed trimer

This is the closest I could get to your exact model. There is a 250R on the site (which includes other models as well). This is the manual for a Husqvarna 26r.

I have a 25cc weedeater 358791030.I need a gasket repair kit for inside of carb. Sears told me they do not have repair kits for inside of carb only a gasket for carb mount.Any suggestions........Thank you.

Look on the body of your carburetor. There should be a set or two of numbers molded into it. Take these #s (they're the model # of your carburetor) and enter them into the Cross-Reference Page on's website. If there is a kit available for the carburetor, you'll find it there.

Husquvarna gas trimmer model 25r need a carburator kit which we cannot find

I am thinking that this is your model and model year (25R 1986-2010 Line Trimmer). Here it is.
Keep record of the carburetor kit part number in case you find it elsewhere for maybe a lower price.

If this is NOT your trimmer, you can look around on this site till you find it. There are many Huskys listed and a few of them bearing the model number you have given. I hope this helps.

My toro 51970a trimmer has been leaking gas and flooding for the past few weeks, but I could start it. Today, it is gushing gas from the back when I pull the starter string. How do i fix this?

The carburetor needs to be removed and inspected. The malfunctions possibly indicate the need for a repair kit. I've been unable to locate your exact model, but if it has the 2-Stroke engine (gas/oil mix), then you will at the very least..need a gasket and diaghragm kit installed per inspection. There is the possibility that the carburetor needs a complete rebuild and would require the complete rebuild kit. Remove the gas lines (after draining gas). Remove the carb and inspect the screws and tightness of the screws in the 2 end covers. Are the screws tight? If not tighten them up and reinstall, trying to restart the machine. Post back if needed.

I have a Ryobi string trimmer that will start quickly, but will not keep running unless the choke is ~ 3/4's closed. I've already rebuilt the carburetor, but that didn't help.

Have you ordered a gasket kit for it? If you have already rebuilt the carburetor and still having this problem most likely means you have a vacuum leak somewhere. Take the carburetor off and look at the intake manifold, there is a gasket on both sides. A gasket kit will allow you to replace both of those gaskets which should fix your problem...hope this helps.
