Is there a file that I can look at to discover the tricks for inserting all 4 pistons into the barrel?
on my engine i just rebuilt,,,, 2 outer pistons at tdc,,,,, wiggle barrel on gently ,,, i used my fingers to wiggle the rings in (oil rings barrel piston first), then as your sliding the barrels down turn crank to bring other ones up and do same,,,,, dunno if this correct way but it worked for me and wasnt to hard
I did something similar but did the inner pistons first to give a bit more finger access. It will probably take a few goes so be patient, make sure the bores are well oiled and make sure your base gasket is the right way round first!
