Hi Bob,

I'm familiar with the website you linked to, and in fact use their run-in procedure for all my ferrous piston cylinder engines. (I have way too many Cox 049s) This 30 of mine has had approximately 4 liters of fuel through it, and have noticed no improvement in compression, but still seems to produce decent horse power, if it were easier to hand start then I wouldn't worry about it at all. Might contact Ken Enya and hear his thoughts on it.


Hi Luke,

I bought it new from Enya direct and had weak compression staight out of the box, so I still have warranty claim on it, would be interested to hear what sort of performance you’re getting from yours, if you have finished breaking it in.


Regards,
Mike.
