Troy Bilt Pressure washer can't pull engine start cord

I have 3000 PSI model 020316 Troy-Bilt pressure washer, circa 2008. Put away in fall, everything fine, no freezing, etc. Went to try to pull cord to start engine, wouldn't budge. Plenty of oil in engine. Is there a pressure valve that is frozen that prevents engine from being pulled over?

 

Remove spark plug and see if it will pull over.

 

Just a reminder! anytime, but especially after sitting awhile hook running water to any pressure washer when trying to start to help prevent pump and unloader damage.

 

Update on problem- pressure pump off, spark plug out, and motor shaft is seized (won't turn with wrench). Engine left unused for 6 months, with oil. Need possible diagnostic on engine seizing up? 5 years old, maybe 50-60 hours on it?
Thanks

I don't see how it could have been fine when you put it in storage and internally frozen now unless it had water in the engine when it was stored. I'd be more inclined to think maybe something got stuck in the flywheel (mouse nest?) or the pump got stuck? I assume this storage was in a dry place?

 

I had a mower come to me one time that was getting fuel into the oil. The engine was a Kohler but just and Idea here. The counter balance was frosen up on the crank. I know your engine doesn't have counter balance in it , but they were frozen up because, when he but it away for the winter the gas in oil turned to gun and froze engine up. Maybe take it apart and see why???? I cleaned engine and it runs great!!

 

I took pressure washer to local small engine repair shop, who will diagnose before any repairs. Said something to the effect that leaking carburetor (not drained over the winter time) can sometime leak into piston(s) and cause lock-up. I will report back to this forum when I get the answers. Normally on my other gas engines, I close fuel shut-off valve and run the engine dry before storage. In the old days I use to take spark plug out and spray preservative into the pistons before storage.

 

If the carburetor was leaking, causing the problem, then it would have turned when you took the spark plug out.

 

I agree,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

 

Repair shop confirmed motor frozen and dead, didn't take apart to find out what failed. Either used/new motor $$, or buy new machine. Bought Black Max 2800 at Sam's for $299 (- $20 for Sam's Card promotion), has fuel shut off valve so I can run dry when not to be used for extended period, and I have always had better luck with Honda engines.

 

I just had the exact same problem. What I did was turn it on each side for a few seconds and upside down briefly. When I let it sit a minute in normal position I pulled it hard and it broke loose. Pulls fine now. It wouldnt start so we started looking and had to replace a fuel hose. I still wouldnt start after a new spark plug and took the carb off. Finally took off air filter and sprayed gas into the intake hole while pulling cord. It cranked first pull, had to keep spraying to keep it running and after a few minutes it ran on its own. I washed a carport and my truck with no problem. Went to wash my uncles house and wouldnt start so we went through the same process again, started and we got house clean. Ran like new. But when cold it will not get gas. Got the motor to turn but is not getting gas. We even replaced the primmer bowl. Almost replaced everything and not running. Ready to just buy another now. Cant keep taking off breather and spraying gas in it to start. Help with this issue???
