Hey ya Guys...
I'm about ready to re assemble my 150 and am wondering if it matters where the gap in the piston ring goes???
and I heat the casing in the oven to what temperature fit the new bearings aye??
Engine cleaning update.... Using a Dishwasher tablet ( with "Powerball" ) in 2 pints of near boiling water cleans the gunk and gum off very well. A wee tip though, Only submerse and let the parts soak for only a quick minute or two otherwise the Alloy casing can go a duller colour. I found dunking for a minute or so and then using wife's toothbrush scrub the yuck off. Oh and I used wife's good pot for the washing too
Then I thoroughly rinsed the parts in hot water and dried off with a dryer.
Cheers Guys, Paul
