cleaning your phazer carbs
seems like todays fuel is kicking most of us in the butt by creating running issues with our sleds. for the 2 stroke phazer owners, its been my observation that alot of you simply arent getting your carbs cleaned thoroughly and are still experiencing some lingering running issues as a result. basically, your missing some key elements in your cleaning process.
not going into detail as to the removal and reinstall of the carbs, i am figuring you have them out and on the bench, accounted for the choke plungers and parts, you already cleaned the excess crap from the exteroir, fuel drained, and ready for some tutorial. do one carb at a time and reference the other and dont mix parts between the two.
with the fuel drained and the float bowl removed, you already found your main jet, its attached to the 17mm bolt securing the bowl to the carb. go ahead and remove this jet and give it a look over. sometimes it helps to have a wrench on the bolt when using a well fitting flat blade screwdriver on the jet or use a vise as the jet can be stuck. this jet, along with the bolt and bowl needs to be shiny and clean. carb dip, carb spray, etc. there should be no residue, blockage, or any abnormality on these parts, or any other parts inside.
with the carbs upside down and the airbox side facing you, you will see two rubber plugs. if yours are correctly installed, they will be on the left and center tubes, the right is uncovered. period. no exceptions.
under the left plug is you pilot jet. you need a well fitting small flat head screwdriver to remove this. careful here, they are easily stripped. dont fight it, if its stubborn, spray some carb cleaner or pb blast and let it soak. give it a bit and keep trying. make sure this jet has no obstructions. you should see the light through it as well as the several holes on the side.
next, remove the pin securing the float. offset needle nose work well here. pull the float out and pay attention as to not lose the needle. turn the carb over over your palm or a tray and the needle will fall. account for it. give it a once over, but its hard to determine its condition. just look at it for a few seconds because.
now grab a 10mm socket and remove the needles' seat. any debris, color, gunk, etc needs to be cleared. consider changing them as a set if they appear questionable.
now for the part that seems to be overlooked most often. on the airbox side of the carb theres also three openings. again, with the airbox side facing you and carbs in normal run position, the opening on the right should be clear to where you removed the pilot jet from. the center should be clear to where the main jet attaches, and the right hole will be tied to the overflows. i am guessing it also helps with pressure in the bowls. if you look closely at the inside of the carb body, on the left below where your fuel line attaches you will see a hole as well as a tiny one directly opposite on the right.
be sure you have good flow through the fuel inlet, all the parts are clean, and you have confirmed all passages to be clear. dont forget the choke circuit, it should be clear to the center tube on the carb.
button that side up and start on the other carb. i am sure i missed something along the way, but its a carb. if theres a hole, something must go in and come out.
