Jets and Timing
For what it is worth, my carb was rebuilt and used the stock jets when the engine was rebuilt last year. Bill Lee of Bill's Toy Shop in Siver City NM did the work
I am at 10,000 in Crested Butte and wheel up over 12,000 and have had no issues with the carb, either starting or running at altitude. I do have the timing set at 12 degrees BTDC. Hope this helps. Terry
