Lawnmower starting issue

[Maddog]

Read this somewhere for hard starting engines. Ti[ the mower on it's side, tank side up. I tip for about 10-15 seconds, then down on alls heels. My tank doesn't leak doing this and it starts with 1 or 2 pulls. Just did it last week. Cleaned air filter, fresh gas, tip on side. 1 pull. I'm with others that it's not a problem with a warm engine. Evidently the tipping and gas runs into carburetor like a choke.

Not a good enough mechanic to explain why it works, it just does for me.

ty
I will give it a whirl

Walk behind mower - had an issue with hard starting when warm. Best I can figure is either the exhaust valve is burned a bit or has carbon buildup. Has good compression when cold but when warm the exhaust valve doesn't seat all the way so lack of compression makes it hard to start. I don't know if I'm imagining it but I run a tank of 1/3 Seafoam 2/3 gas through it every 4 - 6 weeks and it seems to help with the hard starting. Have also used the spray Seafoam where you take off the air cleaner and spray into the carb when running - short bursts a few times then a full blast until the engine chokes out. Let it sit for 20 minutes then restart. Cleans up some of the carbon deposits.

Going on 25 yrs now so it's definitely getting wore out but keep limping it along because all of the new stuff is junk.

Firm believer in Seafoam. Have used it for many years.

Yep others may question why I don't just get a new one.
My opinion is the same, the new stuff would be even worse.

Plus I am a tight wad.

I've used Seafoam in various capacities as well just like you have stated in small and large engines. On the gas pony motor (little v4 gas to start the large diesel 2.375" bore 2" stroke) for my JD 70 Diesel I have put really heavy doses through it when it doesn't rev up like it should and it sure will start screaming after it starts getting that mix into it. Amazingly that little motor has never been taken apart and I hope I never have to.

I grew up driving a 70 JD just like you describe. That was a real pain in the derriere!

Then again, the 24 volt system in the 830 JD wasn't much better.
