Super Cheap Auto. Repco or AutoBarn charge way too much for exactly the same make of tool you get in different packets at SuperCheap Auto for a lot less. You might be able to hire one but you'll probably find it costs as much or more than buying one at SuperCheap Auto. Alternatively an engine rebuilder might run a hone through it for about the same money if you deliver the block ready to work on, and you should get a professional job.<br /><br />There's a hone picture on this page that I pulled off Google so you know what you're looking for: http://images.google.com/imgres?imgurl=http://franklin-tools.co.uk/acatalog/ta140.gif&imgrefurl=http://franklin-tools.co.uk/acatalog/Online_Catalogue_CAMSHAFT___CYLINDER_HEAD_TOOLS _23.html&h=260&w=180&sz=10&tbnid=9wL3rVVz2_kJ:&tbnh=106&tbnw=74&start=23&prev=/images%3Fq%3Dcylinder%2Bhone%26start%3D20%26hl%3Den%26lr%3D%26sa%3DN<br /><br />There are different sizes that expand to fit a range of cylinders covering a range of an inch or two so you need to know your cylinder diameter before you buy one. There are little ones for honing brake cylinders but they're not what you want.
You seem to be better served in the US with local general machine shops where you can take things in and get a quick turnaround.<br /><br />We generally don't have the same things here, unless you're in the know in the trades. It's usually a case of taking things to some kind of specialist or semi-specialist engineering or engine rebuilding workshop where little jobs get put in a queue way behind bigger jobs. Sometimes we can find a bloke who'll do it on the spot but not often.<br /><br />I always marvel at your US magazines where somebody says "I took it down to the machine shop" and got welding / milling / boring etc done on the spot.
Phone for some quotes for having the work done.<br /><br />Compare the prices for buying a hone with having it done by someone else. <br /><br />If it's affordable to have it done by a professional you're bound to get a better job than your first attempt. They also have the skills and tools to measure the bore properly.<br /><br />You don't need a marine mechanic specifically as any engine rebuilder or serious workshop that works on cars, boats or motorbikes would probably have the equipment and skills. And some general engineering workshops as well.<br /><br />If you decide to get someone else to do it, print out this thread and give it to them as an aid as there's some great advice on things like filing out the ports and avoiding damaging the hone in the web at the bottom that should help the mechanic and ensure you get a good result.
A much better suggestion than mine. Local mower shops, unlike local auto mechanics, are much more likely to do the full range of engine rebuilding on two strokes. They'll also know more about honing them than four stroke rebuilers, e.g. the port burr issues that others mentioned. They're working with motors smaller and a lot bigger than yours all the time so they'll have the gear and skills. Reminds me that the bloke at my mower shop is a qualified marine engineer who's helped me out on outboards at times.
Not familiar with that particular little motor, but most have removable heads. Probably just a typo, but you need to take the cylinder itself, i.e. block, rather than the cylinder head - unless they are one and the same on that little motor.
I've busted a couple stones smacking the web....won't no more..
