Thanks to y’all for your notes.
To David & Myron, yeh, IH were quite big in Aust. They manufactured as well as sold.
To Bruce, 1. You are a Lert. I thought the block was hidden. I had that wheel off searching for the serial no.
2.The rear tires are 6.20x12, they could be off a car although they would not make much road contact, they have grooves ground across them supposedly for grip. Like the motor, that’s how I got it, but dirtier (leaves, cobwebs, hornets nests etc.) than the pic. My son in law is an earth moving contractor & he carted it home for me in his tipper from under a gum tree in a paddock he was working on.
3. The 5 hp is what was on it. It is not a long term solution, I am inclined to go 10 or 12. I just want to get the Honda going & run around my yard a bit to check how everything else goes. And herein was a SURPRISE TO ME. The Cub transmission requires the motor to run in the opposite direction to motor vehicles, so the little motor is installed back to front, & the clutch drive disc is mounted on what would normally be the front end of these engines. So I need to be careful that any motor I fit (& here in oz Honda has very good small engines) is strong enough in the front to do the job. Our beaches are sand (see pic) so I hear what you say.
4. Thanks for your ideas on mounting stuff.
To Tedd, OK, sometimes (many for me) the fish are off, so a small Esky might be the go, take the drinks (soft ones for me) out, & bring the fish back. Not sure whether to have blue wheels or white.
To Marlin, thanks for the encouragement.
To Charlie, LOL Appreciate the gig on the little Honda (by the way I’m gonna have to clutch start it, I have had it running on my bench), & honestly thanks for your support & advice by emails.
