Progressing with my Talbot T700, see pic. of latest drive system. I decided I needed a 4;1 ratio drop but this meant a very small pulley on the motor.
Chains do have the advantage of smaller sprockets so I now have a two stage drive with both chain and belt. Testing is being hampered by engine problems however.
From new, it has been prone to kick back when pull starting (Nasty!) and also the occasional backfire. Main problem now is that it stops after a couple of minutes.
Then restarts ok. I guess this means that the carb. is not filling quick enough. Any advice would be appreciated.

It would be easier to diagnose an engine issue with a picture of your engine.

Backfire is more an issue of timing, but hard for these simple engines to go out of time.

Like Vic said, perhaps pics of the motor setup would help.

Wes,

Check the fuel tap, I had a little generator that was similarly troublesome, it turned out to be gunk in the tap, looked like golden hermetite.

That stuff is shellac, it's caused by alcohol in the fuel. It cleans up easy with lacquer thinner.

Thanks all. I decided yesterday that the engine idle speed was too slow. Had to look in the manual to locate the screw! My engine sits very low in the car and I can't see the screw without standing on my head! Anyway, it now idles much more smoothly. But it still jerks the start handle out of my hand. While doing this however, I removed the air filter. When I put the filter back on, the engine stops! The filter is pretty much as new. It runs ok with just the plastic cover in place, i.e. without the paper filter, so I will probably take it up to the local car park ans see if it runs for more than 5 minutes!
