4 months on and we are getting somewhere, had a few issues getting a decent set of Spanish Webers but thanks to the guys at Palmside (Christchurch NZ) we are nearly there!
To condense 3 months of head scratching fitted carbs after checking float height, could not get motor to idle, spitting back, , running on 2 cylinders, could not get carbs synchronised, checked for air leaks, compression, valve clearances, all checked out ok. Bought Misab plates as I didn’t like the spacer and 2 O ring type supplied with the Mangoletsi manifold, bought new non resistor plugs, then resistor plugs when I read that edis likes resistor plugs, swapped EDIS coils and module, finally swapped over carbs and misfiring cylinders moved from 1/2 to 3/4, removed carbs stripped down and noticed this-
See the undrilled opening into the starter circuit, on reflection this was probably not the issue but it was definitely not right and carb was returned to Palmside and a replacement supplied.
Replacement carb was fitted, and voila- still not able to get carbs balanced😡. This time I looked at the carbs first and found a problem with the progression hole drillings
One carb needed 1/4 turn of the throttle plate screw to cover the first progression hole, the other needed 1/2 a turn, these carbs would never synch correctly, 1 carbs holes were drilled approx 1mm further away from the throttle spindle than the other.
This time I sent both carbs back with a request to get a pair from the same batch with progression holes drilled in the same place, a good set came back and were filled and synced without issue.
Moral of the story is if you decide to go for new Spanish Webers make sure you buy from a reputable dealer who will help you sort out the issues!
Next chapter, dealing with that off idle lean hole😄 to be continued…….
