That's the plan, I think the challenge with these things is the detail and trying to get it spot on as close to original as possible. I have been known to be a perfectionist and if I just wanted to get it going really quick I could of chucked the 2hp Briggs on painted it black and painted the base deck red and turned it into a Rover.
Funny you mention the tank, my original was rusted out inside and the filler spout was rusted away to buggery I managed to find a replacement on E-bay that was mint inside for a decent price. Had it been the larger full size tank I probably still would of bought it as I was a little worried I wouldn't be able to source one. I definately agree with it looking out of proportion these Kirby's are a chunky engine and even this little 2hp looks like a 3 sitting on the smaller 14". I still love the looks of the Kirby over the Briggs, you see Briggs everywhere but when you see that Kirby it's like seeing an EH Holden instead of a VW Beetle.
