1 1/2 Stroke

[Looper]

Hi, I've a D1 Bantam that tends to lurk in the shed and only gets started every year or so. I challenged a friend with an old Honda 50 to a race tomorrow but having spent a while on it today it's not going be able to compete. It's starting ok but wont run right, it seems to be struggling to two stroke properly, just a lot of banging and burbling when I lift the throttle. It will then suddenly rev up fine for a while then go back to struggling. In fairness there's nothing really right with the engine, low compression, ancient ignition components, and a carb that needs a good cleaning. Having said that it ran fine a few years ago. I haven't much time or money to spent on it so what I'm wondering is what to tackle first? It kind of needs everything doing but that's not likely to happen, any ideas where to start? Many thanks.

clean the carb and replace the plug i reckon

Thanks mervin, will do. The poor bike really needs some love and attention but time is tight. I'll start there and see if it cures it.

Dump the fuel as well...modern stuff has a shortish life and gums up carbs as well.

The Bantam owners club has a good web site open to non members...a welth of info to be had.
