2001 ec300
#7 slide
45 pilot
a/s somewhere between 2 and 2.5 turns out.
175 main
ddk needle on #2
float is adjusted properly
bike runs great pulls hard and relatively smooth.
carb is clean
but:
sounds like it's 4 stroking at 1/8 throttle.
bike will not idle. zips up and down through the rev range pretty clean, but dies instantly when i shut the throttle
idle screw has no effect.
air screw has little to no effect. i can't get it to idle to adjust airscrew. i hold throttle at 1/16 or so, and i turn airscrew till 4 stroking is minimized.
bike used to idle when it was about 30 degrees cooler.... it would at least idle for 20 seconds or so, then die off. now it just dies instantly.
since it's warmer, i've tried 42 pilot and moving needle up and down (it runs slightly better with needle at position 1...but still no idle.) and 172 main. still no idle (and bike wasn't as strong all around...). i don't want to go bigger on the pilot (48), because i think it will 4 stroke more most likely?
so i assume have 2 choices:
different needle
different slide. - now i've tried a leaner slide in the past on my 200, but i didn't like the effect. plus needles are cheaper
so, any suggestions as to needles that may solve my dilemma? i'vew plugged lotsa things into jd jetting chart, and it seems ddl might be the solution. slightly leaner to 1/4 throttle..
