Pressure washer engine

ldj · Jun 23, 2015

I have a Craftsman pressure washer with a 6HP briggs&Straton OHV engine. Using it today it was running real good with no problems. When I shut it down I heard a strange noise. Went to start it later and it is very hard to pull through like it had pressure in the pump. It doesn't because I took all the hoses off and loosened pressure reg and took spring out. I can't pull it fast enough to start it. What might be the problem?

Take the pump off the motor, see which one is seized. I suspect it will be in the pump.

Have seen Briggs with the flywheel end crankshaft bearing (actually a bushing) seized up.

I have three in my shop. Pumps locked up. Cheaply made pumps.

Just got a chance today to check pressure washer out. I don't think it is pump because I take spark plug out and it turns real free. Put spark plug back and it turned real hard. IMHO it has to be engine problem. If pump I would think it would be hard to pull through with spark plug out. Any ideas?

Make sure the valves are working properly. Also check the fly wheel has not moved on the key.

Flywheel hasn't moved on crankshaft. Valves are working, apparently correct. After more research I find the cam might be bad. Now my gripe, Fuel tank went bad and nearly $40 for that. Now if cam is bad that is over $40. This engine has probably under 25 hours on it. After reading reviews on this engine it just isn't worth putting more $ in it.

About 8 years I had a mower with a flathead B&S on it that needed rebuilt. I bought a Harbor Freight engine that has run perfectly ever since. That engine cost less than the parts to rebuild the original engine and at $80 it was about the same as 2 parts for this B&S Intek. I had always bought made in USA but when I can buy China engine complete for the price of 2 parts on the B&S, guess what I'm gona do?

Decompression part of the cam could be broken. I have seen that a few times. Parts prices are getting out there. I have an intek engine in the shop.
swallowed a valve. Parts will cost more than a new engine.

OK, since you set valve lash with piston 1/4" past TDC in order to get the decompressor out of the way, then shouldn't there be a difference in valve lash at TDC and 1/4" past? If there is no difference then that would prove decompressor isn't working? If not working and I set valve lash at say .001 or 2 would that open that valve just a little early relieving a little compression. If it is stuck and not broke and if I could get it running with some b-12 or something it might free it up. Just thinking outside the box.
