Hi davo, you should have no probs using the GX100, with the alloy clutch...I have had a Honda G100 2.5HP on a late model Scotty 45 for years....works perfectly...Here's a pic...
To put your mind at rest, the 14" 45 would have had a Briggs originally...so its a win / win situation Looking forward to seeing the pics when its completed.
