Starts only with Carb spray... blowing my mind

I changed...

• oil
• carb membrane
• cleaned all carb paths
• cleaned air filter and squeezed it from oil
• Spark plug

But still starts only with Carb spray into air filter sponge... :confused3:

First thing to do is check that the choke butterfly is actually closing ALL the way and adjust the linkage if it isn't. Check that there are no air leaks at gasket points, carb to manifold and manifold engine. In very rare instances if the choke butterfly has two holes in it I have blocked one of them with a small short bolt creating more choking affect.

Might help if we knew what engine we are talking about.

I don't know the model but carb looks like that:


And I have to note that run good after it have been started.
And also starts from first yank while still hot (30 minutes).
