Well I always preferred Wilesco to Mamods
not from design more from quality. One important
detail is the Sight glass which is much better by Wilesco -
Is it possible that the Flywheel received
a blow during transport? This is not acceptable
for an Industry product of today. Sure it is
a toy and not made in China - but it is too bad.
The piston rod looks too loose but that could be
correct because of thermal expansion.
Hope you will get an answer shortly
