Finally got it running. But running like a bag of nails. Not all plugs are getting fuel any ideas ?

Defo sus as I swapped them over due to the storms being electric choke and land is manual

All running before and working just no fuel to the plugs

Engine was running fine. Sus were ok but needed cleaning out float levels seem to be correct as they were working perfectly before. Just can't get fuel to plugs. Would it be worth putting fuel down carb throat to see if she will start and pull fuel through?

Replaced sd1 engine with range rover v8 engine on su carbs. Strong spark fuel to the carbs. But nothing going to the plugs. Fuel pump seems to work as it should. Any ideas thanks
