Improved Running
09/14/07 at 08:12:32

Hi All, 2004, all stock. After new plug, clean carb twice, change oil and filter, adjust valves still ran like crap at low speed range. Okay at higher RPM. New pilot jet, 55. better but not good. Pulled plug to adjust idle jet. It was turned in all the way. Took a bit of force to back it out. Set it at 1 1/2 out. Better but still sluggish on smooth acceleration from low speeds. Took out the doughnut thingy on the needle and replaced with a shim/washer 2/3 thickness of original doughnut thingy. Runs perfect now. My thanks to all who post on this board. Probably would not have done the doughnut thingy. By the way, the plug over the idle jet is the same diameter as the doughnut thingy. When you drill the hole to use a sheet metal screw to remove the plug use a bit the same diameter as the needle. Just luck that I did. Again thanks to this board.

Are you telling me the only way to get the plug out is by drilling? OY!
I hadn't heard about having to do that, I'm dangerous with a drill!

Re: Improved Running Reply #4 - 09/14/07 at 11:29:11 Once the drill has gone deep enough to have the oputside edge below the surface, decrease the pressure, also, if you will wrap the bit with a few layers of tape, it will stop the drillbit from slamming thru & wrecking the pilot screw( brass) behind the plug

you DONT have to drill..small framing screw for metal studs/track is what i used they have a phillips head on them screw driver in easy 1-2 1/4 turns till it grabs(not TOO far or you hit the pilot head) or the plug spins(easier on newer bikes)pull out by gripping screw head with good pliers/vice grips... home despot has them but you have to buy 1000 at a time!!!some hardware stores have them by the piece..

I'm pretty triggerhappy with drills, which most of the time is what you need (especially with carpentry). I'm glad to know it's only the pilot that I will hit if I go too far, I'm putting in a new one anyway. Think I'll go see if Lancer got them in yet!

I believe you are getting the pilot jet which is inside the carb and pilot mixture screw which is hidden behind the plug mixed up. Those who know more may correct me but I am pretty sure they are two different things in two different places

Max says, I hate to rain on the parade, but, I believe the idle mixture screw, AKA pilot air screw, controls primarily fuel + or - rather than air although there is usually some air bubbles in the mixture at this point. When you turn it in(clockwise) it decreases the fuel in the idle A/F mixture to the point many engines die for lack of fuel. When you turn it out (CCW) the engine runs richer (more fuel than air for correct operation) and the engine gets an uneven idle and usually some black exhaust. There has been units that use the air for idle adjustment, but as the A/F ratio by volume is very large that passage and tapered adjustment screw has to be very large to be effective. From the retired auto shop teacher.
