Hello everyone,

my Fronty with a Zenith HP5A carburetor is back firing in the carburetor. How can I make the mixture richer? Can someone help me with a instruction for this carburetor?

Thank you for your information.

You have to change the jets. If you cannot find replacements you can drill them out a little at a time or machine new jets with a larger hole.

I make an adjustable main jet conversion for those.

I've probably make a couple dozen of them by now and have an HP5A and a couple HP4A & HP4U waiting for them.
