Setting up an OS 1.60, cline, bisson pitts, 18x6w (finally solved)
Okay,
Got my cline regulator installed tonight and did some tuning. Currently I'm running the needle out 3/4 of a turn and the mixture out 2.5 turns from closed with the barrel closed. The engine seems to idle lean and it makes the dull brrrrr sound instead of your typical 2 stroke idle with the periodic misses. When I go to full throttle it jumps up instantly, and starts to build rpms pretty fast until it gets to about 1000 rpm shy of max then hesitates though that last little bit. I was thinking I my have too much timing with an OS 8 plug and 15% fuel so I tried the cold F plug just for kicks but it didn't seem to make any difference.
Here is the setup:
15% omega
APC 18x6w
cline regulator
bisson pitts muffler with tapperd ends cut off.
The engine ran well and peaked at 9150 rpm so this combo works, just need to work out that last little bit of transition.
Anyone else with a similar setup care to post their setup so I can compare notes?
Thanks,
schu
