I had a carby that I modified yesterday that I could not get to come back to idle. I had fitted 5 washers under the cam , this was reducing it but it was still way to high. Got another carby body, swapped all the internals, 3 washers under the cam and it works perfectly. Out of all the carbs I have modified I only have 3 bodies that won't work for some reason, the one yesterday an 2 previous ones that would not start. Remove the internals to another body and no problems. Why I have no idea
