Hi,

I'm new to the forum, but have used my .53 for almost 4 seasons without putting a spanner on it!

In the last few weeks it has become increasingly difficult to start to the point of not running at all yesterday!

Previously it also started to 'hunt' when idling - particularly at the end of a flight with a hot motor.

The only other problem that I've had (and fixed), was the main needle leaking - cured with a new O-ring

I'm checking the valve gaps this evening with the help of an engineering minded friend (sadly the good lord didn't see fit to make me useful with a box of spanners!).

Is there anything else to look for/be aware of?

regards

Julian
