I do find that when they are cold they take a little longer to get running but once warmed up they are great.
Exactly!
I've often explained to owners of these and the identical Tower Hobbies engines, that they need to leave the glow ignitor on for 30 seconds after starting the engine for the first time in the day.
Then run it up a bit to get the head warm.
Once done the engine does very well there after.
