A little help, guys, please.
Zenoah G-23: won't turn up over half throttle (4,500RPM). Idles reasonably well, transitions nicely (until that 4,500RPM peak).
Regular gas w/ Amsoil at 85:1 (1.5 oz./gal.). 20-6 prop. Medium fuel tubing, gas tank (sintered bronze pickup) and gas line (CubroFinal Filter) filters. Dubro fuel filler inline.
Carb and fuel lines taken completely apart and blown out.
I've heard that it's either not broken in yet or I'm running too large of a prop. Let's hear some opinions. I'd really like to run a 20" prop. Is there any way to make it work? Dr.1 Driver "There's a Hun in the sun!"
