Data points: warm engine @ 160* and 65 psi oil,
timing 10* advance
Brand new plugs, sparkling white after 90 miles.
<span style="color: #990000">( I enriched the carbs 1/8 turn as suggested.)</span>
Balanced the carbs with the Unisis tool angled at 45*
I covered the main opening, the rectangular small opening
and the the tiny round hole in the upper left.
Same spot both carbs. Reconnected the throttle shaft
and got the carbs to twitchy 900 rpm warm idle..
Stuck a hose in each carb and heard ???? got me.
Front carb: lifted the piston a wee bit- a brief quickening.
Front carb: lifted the piston 1/4 inch- engine died.
Rear carb : lifted the piston a wee bit -nothing happened
Rear carb: lifted the piston about 3/4" - nothing much changed.
What is my rear carb telling me to adjust?
Here's my N0 6 plug with 90 miles on it - before I enriched
the carb 1/8 turn clockwise last hour.
thanks, d
