Error in Previous Post - Total Timing NOT 42 Deg
Hey guys -The title pretty much says it. I can't read the numbers on the damper. Rechecked my timing while totally awake and the real numbers are 22 initial, 34 total. Exactly the same as when the engine was dynoed by the builder. Rdorguy, I tried the small tap on the primary accelerator pump and to my amazement the engine almost died! Recovered immediately, though. So I'm either too rich or right on the hairy edge. Since it idles fine and the idle mixture screws are about 1 1/2 turns out, I'm thinking the latter. But I may be too close to the edge since I tuned it with the air cleaner off.
I think timing is OK so I'm going to retune the carb (this time with the air cleaner on), and maybe try smaller primary pump nozzles. Will probably check the idle transfer slot unless a dramatic change occurs from retuning. It'll be a day or two, since I'm wrapping up another science project - I'm measuring the pressure loss caused by my remote oil filter setup.
Thanks to everyone for all the help. |
