• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

My last plane didn’t have a primer system and never had an issue starting, even on cold/high humidity mornings at 4125MSL. Three pumps on the throttle, hit the starter and we’re making good engine noise. My Hatz came with a primer and I’ve used it occasionally with good results. I just returned from a six week trip and with the standard three pumps, she fired right up. The morning was about 60f and around 80% humidity at 110MSL.
The question is, why do I need a primer? To me it’s another source of potential problems and I’m ready to pull it out and go with the tried and true three throttle pumps.
Can anyone please tell me why not to pull it out?
Thanks!!
