Hello everyone. I got an os .91 engine and have been having a difficult time getting the electric starter to spin the prop fast enough to get it started. I have been using a new(2 month old) Hobbico battery and have a new standard starter that works just fine with an os.61 that I have. I believe the battery is getting a good charge and holding it. When the engine does start it runs like a top.

I have no idea when an engine gets large enough to need another starting procedure. The largest engine I have any experience with is a .61.

Motorcycle battery, car battery, something wrong with engine (compression feels "good" to me)? etc etc etc

Thank you for your help.
