She's charging nicely at about 14.4V, so no issues there.
Battery Voltage was showing at over 13V before I tested her (after 25mile drive home). Probaby won't drive her now till Saturday, so will check the voltage drop before I start her.
I also wonder if I'm 'over choking' her on start up? I usually try her on full choke first - I might try 1/2 to 3/4 to see if that makes a difference.
