I have a 1958 MGA with SU carbs. It has become very hard starting. When it does turn over and start it begins like it is not running on all cylinders. Than it kicks in and runs fine. Takes a long time to idle before I can disengage the choke. While at idle if it drops below 900 RPM the engine cuts out and has to be restarted. When first started at times there is a backfire in the engine compartment not the exhaust tailpipe.
Any suggestions greatly appreciated
Thank you
