Hello to everyone..took the 54/235 out for a Sunday ride after advancing the timing and replacing the condensor and the new re-built carburator did need some more tighting as per your instructions. It all worked out great we had a lovely ride on Sunday about 35 miles round trip! OK...once in awhile while decelerating I will get little BABY backfire farts not many...do I need to advance just a bit more or leave well enough alone as I did not get any pinging and the idle is fine and so is starting up. This was the first ride where heading for the side of the road was not needed and it did very well up a 6 percent grade at 50-55 just like a truck should...what do you think? THANKS, Steve
