Customer Question

The red primer button sticks after the first push and takes a long time to come out again. Although the engine starts first time it only runs for a couple of minutes.

Hello there,

I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Please note, I am just a moderator for this category, I can only try and find experts to help, I can't answer the question itself.

Thank you!

Yes I'm happy to wait a little longer for an answer. But I would like to cut my grass soon.

We will continue to look for a Professional to assist you.

Thank you for your patience,

Take a look at this carburetor. It seems to fit the unit you have. It looks like the check valve under the primer may be plugged, or the passage from fuel tank to the primer could be plugged, but one of them is not letting the fuel enter the carburetor for running. Here is link.----

Thanks a lot Curtis. The link is a great help. Just one more question. If the check valve is gummed up, is there a proprietary product I can use to clean it without dismantling? Like Redex in a car engine?

Try some spray carburetor cleaner, or some Sea Foam, but the primer will likely have to be removed to get to it.
