I have a Chore MAster CV-2300-OMBC with a Briggs & Stratton

Customer Question

I have a Chore MAster CV-2300-OMBC with a Briggs & Stratton engine. The engine won't run unless I push and hold, sometimes pump the primer bulb. Thoughts?
JA: I'll do all I can to help. Tell me a bit more about what's going on so we can help you best.
Customer: It's a pressure washer that hasn't been used in several years and probably has only been used a total of 4 times overall. The gas tank was empty, filled it up and the issue I described occurred
JA: Is there anything else the Small Engine Technician should be aware of?
Customer: no
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Small Engine Technician about your situation and then connect you two.

Hi my name is ***** ***** welcome to Just Answer. Does your engine have the side mounted gas tank and air filter that bolts on top ?

Customer: replied 10 months ago.
No bolt on top. Pictures attached. Gas opening on top left side when facing machine, filter on left side when facing machine. See attached photos
Expert:  Briggs-Fan replied 10 months ago.

Ok under the carburetor is the bowl bolt , it has ports in the sides and one in the top where it threads in. You will have to remote this using a 1/2 inch socket and when you remove it gas will runout , once youbclean the ports in the bowl bolt you can put it in and tighten it up

Customer: replied 10 months ago.
All I got was gas all over my hands, etc. Thanks for the heads up, I was able to capture a lot of it in a plastic bowl. Didn't solve the problem. Giving up and taking to a repair place or giving it away :-(
Expert:  Briggs-Fan replied 10 months ago.

Did you clean out the ports in the bolt ?

Customer: replied 10 months ago.
The bolt was only about a half inch long, didn't see any ports. Did clean out the bowl and the white plastic thing
Expert:  Briggs-Fan replied 10 months ago.

Ok take the bolt out , there will be holes in each side and one that is in the top of the bolt where it threads in . I used a sewing needle and gumout carburetor cleaner. I take the red straw and shoot carb cleaned down into the top hole making sure it sprays out the side holes

Customer: replied 10 months ago.
Are we talking about the same bolt. The one I took off was holding a brass colored bowl under the carburetor, is this the bolt you are referring to?
Expert:  Briggs-Fan replied 10 months ago.

Yes it has a gasket type washer around it ,

Customer: replied 10 months ago.
Just getting in shower so I can go to an event. Will try again tomorrow. Thanks
Expert:  Briggs-Fan replied 10 months ago.

Ok , grab a can of carburetor cleaner and some rubber gloves , it's that bolt

Customer: replied 10 months ago.
Ports all cleaned out still won't stay running. Starts then cuts out right away, unless pump the primer bulb.
Expert:  Briggs-Fan replied 10 months ago.

If the float and needle are dropping the last thing is the main jet of the carburetor. Did it sit for a while prior to this problem

Customer: replied 10 months ago.
sat empty for maybe 2 or 3 years
Expert:  Briggs-Fan replied 10 months ago.

The needle could be stuck, or the main jet blocked , you also need to keep a eye on the oil and see if it is thin or smells like gas . Even when the tank is empty on these engines the carburetor bowl is full of gas so it may have gummed the Jets of the carb up

Customer: replied 10 months ago.
Will check those items, Thank You.
Expert:  Briggs-Fan replied 10 months ago.

Let me know what you find , have you also removed the gas cap and see if it will stay running
