Got a 1983 1.9 wbx
Was a non runner, but got it running sweet. However if i havent started it for a week, it either wont start, or will take ages to start. I know fuel is getting to the carb, cos i can smell it. I have chaned fuel lines, spark plugs, rotor and dizzy, HT leads were new when i bought it, new exhaust pipe (back to stock from empi twin) had oil change and oil filter done etc. Only thing not changed is the coil and fuel pump. The fuel pump must be working as fuel gets there fine and i have had it running well before.
Could the coil be my obvious choice? Yesterday it wouldnt even start. Also should i check each plug is sparking? And can i tell if the coil works by testing it in any way?
this is a pic of the engine , the coil doesnt look like any i have seen before, could it be the wrong sort?

Any help would be great. I want it to start on first/second turn really.
