I've just picked up a series 5 Gem, number G47705 with what I understand is the Howard twin 360 degree engine.

Two problems are immediately obvious, firstly, the chain is very slack and rubbing on the casing. I've ordered a new one, but is it OK to fit a new chain to old sprockets?

Second issue is that although it has good compression on both cylinders,and it starts easily and runs fine, it tends to cough and splutter under load. The plugs look fine with a good colour, so I don't think it's a mixture issue. Any thoughts on what I should look for first?
