ignition and upholstry

The work has stopped for a while the ignition timing has not been correct.I have tried to start but it did work for only a halve a minute then a bang!The upholstery is next step I have a help from friend who has measured and planning to do the work in January.The rear window in wood is a copy being made due to the bad shape for the original one.I am also planning to buy new rims and tires.
