Did you check the timing? And how about timing advance?Water in tank from bad fuel? - happens all of a sudden - I think it is that based on description of what happened.

you need to change the fuel gauge, fuel gauge goes bad so does the temp gauge, runs thru fuel gauge then to temp

The first thing to do is check the engine for vacuum leaks, use a can or Carb cleaner, spray around the top near the intake gaskets and see if the engine idle changes, if it does you have a leak.

If you are starting it like that, you have a bad starter or you need to replace your key and tumbler

Most likely the hydraulic line wasn't properly installed on the clutch slave cylinder or master cylinder, causing a leak. If the fitting was cross-threaded, it may have damaged either the hydraulic line fitting or the cylinder it goes into. Have whoever did the work fix this at their cost.

Fuel pump, clogged fuel filter or clogged air filter

EGR valve may be sticking open

on the bottom of the steering cover ther are 5 phillips tiped screws you may have to get down low to see them

If its knocking with low or no oil pressure, then your bottom end has failed at some point, and the engine hasn't got much longer to live. If it runs fine and has oil pressure, chances are its the top end, these engine use solid lifters and may need adjustment, but from my experience they are always a little noisy even when the lash is correctly adjusted.

Try using your emergency flashers. If all the bulbs are working, you don't need to replace any fuses. More often than not, the flashers go on these older rigs. Fuses rarely fail unless there is a much larger problem.

I built these engine on the assembly line ,couldnt you fit a OHC cortina engine as in the UK its not a issue with the paperwork and technical engineers like it is here in spain but finding a kent 1.6 GT lump with a webber carb nowdays ? ever heard of a brown stuff from a rocking horse?

If the problem is occurring or corrected while wiggling the switch, remove the switch assembly and check for loose ,corroded or burnt harness connection. if it looks ok, problem may be within the switch itself, replace the switch assembly and recheck.
