Hello, and thanks for a great forum.

I have pulled down the engine of my newly acquired Super 600, which I am happy to say is in quite good condition and seems as it was reasonably well cared for.

It had starting issues so cleaned the carby and went through checks as outlined here in the archives, but still had issues, so decided to check the piston, rings and bore, mag, module and seals. Even though the piston rings and bore are in fairly good condition decided to replace with a re-bored barrel and piston which I bought from an acquaintance at a very cheap price, (can use original for another Power Plus that needs it). The bottom end seems in good condition so I will leave that alone.

1. How important is the muffler that go's with the high compression head? The Super has HC head but standard muffler as does the Power Plus. According to my research of the archives the HC head is supposed to have the muffler with the extra holes drilled in the baffle and denoted by a hole drilled into the outlet.

2. As careful as I've tried to be I am worried that some of the cleaning etc. may have contaminated the bottom end. Could I flush out with Kero or diesel, blow out and squirt a small amount of 2 stroke oil near the bearings before assembling the top end?

Will get to carby later.

Regards,
Bushie.
