Flew/started my 58 for the 1st time yesterday. I had a BME 24/10 on it and turned 6200 rpm with the high needle 1 1/2 out way rich. Bisson muffler is also restrictive I suspect.
Initial mix 32/1 as per the maual
It was very easy starting except for the tendancy to run backwards which threw me at 1st.
I must say I was impressed as it hauled my Ultimate around with ease.
