Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

My ts 2 3/4 Hp motor is a little sad at the moment . Does anyone know of a motor rebuilder in Australia or Queensland that will rebore the cylinders and do a crank shaft regrind. Have another set  of cylinders that are standard but there are tracks where the gudgion pin buttons are. Does anyone have a reasonable crank and or cylinders and pistons to suit for sale. Cheers Conrad


Hi Conrad,

I've had 3 Douglas motors done by Neil at ReCo - rebores, regrinds, bigend shells etc. I think he likes working on the older stuff (despite the frustrations they throw up sometimes!)

Cheers, Keith...

another company up your way is Beaudesert Engine Reconditioners. I found them very helpful and a prompt service for barrel boring.



Thank you Kieth and Rob for your replies, Facebooked Reco Engineering and found photo's of work done on a 1914 Douglas barrels and crank. Will give them a call during the week to find out more. Cheers Conrad


Hello , My T/S motor has been rebuilt. New valves, guides, valve springs, bored to 20 thou, new pistons and rings, crank straightened and new big end shells. New crush washers to Inlet pipes and valve caps. Long reach spark plugs installed. Motor starts easily, with only the air slide open to a 1/4.  Can rev up using the air slide , but when adjusting with both air and fuel the engine want to stop. The carbie is an AMAC. Is the fuel jet to large or small as it is a 27 jet. Is there settings that I am missing? Cannot run with part or full fuel on the slide. Any Help. Cheers Conrad


Hi Conrad,
You'd expect starting to be with air closed, throttle half open. Are you sure you're not mixing up the levers? Throttle is the long lever, goes to the slide closest to the engine.
Jet size is something like AMAC 25-27, which is 0.026" to 0.028". Don't believe what's stamped on the jet. If you don't have tiny number drills, an easy way to measure is with a tapered needle of some kind (I raid my wife's sewing basket for a darning needle). Insert the needle into the jet, mark where is stops, and measure the diameter with your micrometer/vernier.
If you're still having trouble, post a photo of your carb so we know what model you've got.
