G'day folks,
You may have issues finding anyone to do the rebore - half the places just don't seem interested
I can't see the differences between these blades and the 1974 onwards ones, but happy to be corrected
I would suggest putting in an EI module as well whilst its all apart - bypass the point and you will never have to worry again
Yes, it is indeed difficult to find someone who does 2-stroke rebores - there is one bloke around Garfield in Vic that I know of, who does these for the 'Forgotten Era' class of classic 2-stroke racebikes.
However, what Victa servicing dealers used to do, back in the heyday of the full crank 2-stroke engines, was to stock 'service exchange rebore' barrel/piston/ring etc kits. When we fitted one of these kits, the barrel removed from the mower went off to the reconditioners for reboring, and a fresh kit was returned to us. A Victa barrel can have several rebores, at oversize increments of 0.020"/0.5mm, before it becomes unserviceable BTW.
Now, the point of all this is, that GA Spares still offer these 'service exchange rebore' kits, via their dealers.
You take/send your old barrel to the dealer, who inspects it to determine whether it is OK for reconditioning, i.e. that there is no damage/over limit bore etc, that would render it only fit for scrap.
Or, you can pick up the kit, and pay a 'core deposit' - which is refunded when/if you take in your old barrel, and it checks out as OK.
Edit: And in re the Electronic Ignition module fitment; it's simplest to leave the points and condenser in situ - that way they're still in place as a backup, if that should be needed.
Mystyler, that's the correct blade/bolt set you have - the final letter of the part number is just a supersession code.
