Does anyone know the correct spark plug gap setting for a Sears/Craftsman blower/vac, mdl 358.797342 25 cc motor

is it a Single motor ?
photos would be helpful - of switch
& motor/cap. wire conn.

Take the spark plug out, turn ignition key or pull rope until the engine turns over several times. Let it sit for about 5 or 10 minutes and repeat. Replace the spark plug with a new one. Make sure that your crankcase is not over filled or under filled with oil, and make sure that there is plenty of gasoline in the tank. Make sure that gasoline cap and oil cap are on "securely". Now try to re-start. (The engine may smoke for a while, but it should clear up in a few minutes).

Most wet dry vacs have a ball float that blocks the vacuum when it is full of liquid. Yours sounds as if it is full or the ball has gotten stuck in the up, or blocking position.

Yes it can. Below is an item # for a 2HP motor being sold on Ebay: Item number: 280564320553.
If yours is a different HP, do a search on Google for "Shopvac motor replacement". I also recommend that you call sears - maybe your vac is still under warranty? Good luck.

Hi, I know on my Craftsman shop vac 2 different sizes of vacs that I use, I try and stick to the craftsman filters, but you can use other brands if they are not available or you want to save some ( $ ) ? As far as a manual for this vac, more then likely you will have to go to the maker and distributor as Sears, O.C.Hardware also sell there products. You may have to go with a manual that is the same peak H.P.and gallons that covers all different makes and models. Filter wise, make sure you have the right ones on or off when using the wet or dry pick-up settings.

Ron, Kenmore assigns model numbers pretty much sequentially as they receive new inventory. There is no cross reference anywhere in the industry for their product except in their catalog. If you want to compare features you must do it that way to find a similar vac. If you are very luck you may find an experience Sales rep at Sears.
If this is a Kenmore canister , as they age the hose and wheels and wand connections break down. For a better designed or improved vac, look at a professional vac shop and look at all the spots which broke down on your old one. If there are feateures you like make note of them too and you should find similar features on a pro brand or at Sears.
One more thing, don't buy a new vac based on amperage. Amperage is consumption of power NOT output but its a big deal to advertise that way. it's only a numbers game. A 12 AMP vac motor with its suction fans removed is still a 12 amp motor, it just has no suction. Anyone who tries to sell you a vac based on amperage does not know there business. Best of luck. For a lighter easier running vac,better design look at Sebo , Miele, etc, as well. The Europeans are far ahead in design and filtration and durability

Hi,
Yes there should be a filter fitted onto the top section.

For suppliers, it would be cheapest to find your nearest stockist, or buy online and have it shipped. It's still current stock - so spares should be readily available.

Sears stock it -
CRAFTSMAN FILTER

Thank you for using Fixya,

are you using a water , foam material filter?

I just picked up a similar model someone was throwing away. turns out there is a thermal fuse inside the motor housing that blew. I just need to find the values of the fuse and repalce with appropriate size. motor runs when fuse is bypassed.

Either you aren't getting the top on correctly so it will latch, or there maybe a problem with the latches. You should have a one year warranty on this, take it back to Sears and have them look at it.
