So sometimes the engine starts when it wants and sometimes it doesn’t. It’ll take a couple key turns before it actually starts. Does anyone know what could possibly be the culprit?

starting involves proper choking when cold or dormant for hrs... carbs must be 100% clean especically low speed cct.

check fuel pump fill (reprime) carbs check fuel hose check venting

Yes battery has been tested and is fully charged. Yes we are pushing the choke in and holding it while we turn the key.
