Fouling plugs? Update 9/2/08

[bassarama]

Ok, got another bug out of the motor, after checking the new plugs with a precision gap gauge, I found out the old plugs were set at .035, that said, I set the new Champions at .035 and checked for fouling, all tested fine.
If you read above, last time I was out cruising around, I couldn***8217;t achieve my 42 mph top speed***8230;I had reduced the fuel from 40:1 to 50:1 and installed a new set of champions. The fact that a few days ago I had been working on the starter motor/ground cable, decreased the gas mix ration from 40:1 to 50:1 and installed a new set of plugs, this lack of top speed got my attention***8230;

The throttle linkage was the obvious place to check and here***8217;s the problem; as you can see, the missing piece of rubber sleeve is the reason the throttle linkage didn***8217;t open the carburetors all the way, thus the lack of top rpm***8217;s > speed:



As you can see, with the new slightly over size sleeve, the carburetors linkage opens all the way, there***8217;s still about 1/16***8221; of gap between the offset cam and the sleeve, this leaves enough play so that I can engage forward and reverse without accelerating right away.



Update: 9-12-08, plugs after running at WOT, 5500 rpm's:





Here you go guys, a couple more pix for the record***8230;

Thanks for helping out
