Hi dd


Yes Those main jets were too small is it ?
Those are Primary 75 and secondary 45
do i go for factory size or little small ?
i don't know my carburator exact condition

But my Spark plugs were dark black and car was smooking on above 1000 higher rpm, that is what i was thinking why they did not become white shal i change my power valve too it is currently running 50 but factory size is 60


thanks
regards
sumith
