Did this video help you?

Rick S: Great presentation as always, Sir. You know, something good came from the hydro-locking. 1) The muffler and deck got a good rustproofing and 2) the clouds of exhaust smoke put a dent in the mosquito population.

Jay Marlette: Can that same process be used on my Coleman 1850 generator?

foodbandid: Dony, Mr. Wonderful stored the mower exactly like you showed, and of course I couldn't pull the cord. He was ready to curb it, but it's a troy built and I like using it. My question is: since I put new gas and new oil in will I have to drain both out before doing this?? AND is carburetor cleaner the same thing as quick start??

sypher0101: My mower is doing this very thing, pulling the cord, it becomes very hard to pull.
I picked up the mower 2nd hand, and didnt have this issue. The mower was filthy so i took off the engine from the base, removed carb and gave good clean (outside). re-assembled everything and the pull start issue happened.
I may of had the engine on the bench on an angle and possibly built up oil in the piston, but trying the tip from you video, no excess oil would come out of the spark plug hole. Any other tips?

gabe st angel: Thank you for the helpful video, ended up gettting the lawnmower running and i burned off the oil like you said and its running great!

gabe st angel: Wow, my dad was set on buying a new lawnmower because it "broke", go out there and the spark plug was completly dethreaded, could this be because the hydrolock built up enough pressure in combination with trying to pull start it? Thought it was weird...

ace The King: WOW THANKS MAN MINES STARTED ON THE SECOND PULL! almost gave it away lol 

Mo Kleit: Thanks for the video. very helpful.

Mario Melendez: Hey donyboy, I got an echo blower pb 500 T and I too believe it is hydro locked. Pull cord will not pull at all. I removed the spark plug and it still won't pull. Any suggestions?

Benjamin Ovre: Don't forget to check the oil level afterwards! Great video

friendshipyu: ha ha it really smokes like crazy, like a twin engine with one dead cylinder. You are fun, Don

Oscar Betancourt: I give you five stars buddy.

J Mex: thankz very much!!!!

jayed1254: Thank you Donnyboy for helping us understand the motor problems we encounter.   Straight talk is the best!

Daniel Robert: Yeah but, holy smoke, what's your secret for maintaining somekind of a relationship with your neigbours ?

anniversary4: Can a lawn tractor hydro-lock with gas?  My Craftsman with Briggs 18HP single cylinder Intek seems to be. It was really hard turning over so I removed spark plug thinking it may need valve adjustment (learned that tidbit from another one of your videos. When I tried turning it over with plug removed lots of gas came out of plug hole. Looks like I may have messed up rebuilding the Nikki carb. Briggs manual for that engine shows both a Walbro and a Nikki carb. Some people say that the Nikki carb is sensitive. Do you think I can or should switch to the Walbro? 

tom k: Thank you Dony. I overfilled my chipper with oil. I found your video, removed the spark plug and the oil came pouring out.  Was able to start and am now back in business.  Outstanding!

Jake Roll: hi its me again here is the engine with the problem I was talking about.

Jake Roll: I am thinking about buying a Robin Subaru horizontal shaft 7 horsepower with idle control came off of a power washer and the guy said it was hydro loching is there a way to fix it. I need to know if it's safe to buy if it's easy to fix?
