| Subject: | |  re: only runs with choke
I noticed that all the FE290D carbs in the Kawasaki parts book have #45 pilot jets in them, you said yours was a #42. Since we are running out of ideas, I wonder if the change would help? PN 92064-2083 Double check the number on yours. Don't know about your swap meet tach. We use the ones that have the wire that wraps around the plug wire. tinytach.com

Bad, just thinking about your "stumble" There is a spring that goes the length of the link between the governor arm and the carb throttle plate. PN M94839, this spring holds tension on the linkage and has to be fastened on both ends for the throttle system to work properly.

Not wanting to steal the subject here but I have looked and looked at this spring trying to figure out what it does. Mine was broke but the pictures shows the spring connected in the same holes as the linkage. I just don't see how it does anything.
Can you explain?

The spring holds tension on the linkage so the throttle doesn't flutter. This spring keeps a solid connection from the governor arm to the throttle plate regardless of how much slop is in the linkage. And yes,the spring hooks can be in the same holes as the linkage.

| re: only runs with choke
I have a 19 month old CX with the same problem- only runs with choke. Gradually got worse. I brought it in to the dealer yesterday as CX's have 2 year warranties. When they tell me whats up I'll post but I'm thinking my problem may be what a previous poster said- fuel pump.
BTW? did your problem start gradually (only occasionally needing choke to run followed by a period of normal operation)?

Thanks much. I put the new spring on today. Gradually putting my rust bucket back together.

| re: only runs with choke
well thought i had a breakthrough yesterday, buddy of mine said change the fuel line it is probably collapsing choking off the fuel. i started the motor an squeezed the fuel line and coulda swore that the thing ran great - so i called my friend and said yep that was it, bought new fuel line and still runs like crap... arghh
i pulled the valve cover off tonight, pulled the rockers too, the valves seem to have a bit of dimpling in them (exhaust is ever so slightly worse than the intake) should there be any dimpling at all on these or should they be completely flat? only reason i ask is because the rocker adjust appears rounded like it came from the factory.
I also did my best to look in the tank for something stupid like a leaf or something getting drawn into the suction tube... nada
would like to have pulled the tank out and flushed it but it doesn't appear that this would be a very easy job w/o pulling all the brake and shifter linkage
ok...
so a recap so far
new plug
new air filter
new fuel filter
new fuel pump
new fuel lines (tank to pump,pump to carb)
checked the tank, pulled suction tube to make sure it is clear)
gonna show my neighbor tomorrow (hopefully) where i am at and pick his brain too (he is a mechanic by trade)
any ideas please let me know
thanks in advance

i have ony owned mine for about a week now so probably not much help in answering this. but i think you are right, guy i got it from said it ran great last year, sat over the winter and ran like crap w/o choke this year (he puts stabil in all his tanks religiously and i have cleaned the carb myself at least 2 or 3 times now

Very very anxious to hear what your issue was with yours so please post. I am pulling my hair out about now. would take it to the dealer but frankly no funds at this point (still paying for the gator) hahaha..

| re: only runs with choke
Slight dimples won't affect the adjustment in the valves. One last idea from me. Check the vent hose for the gas tank. It comes out the top and runs thru the frame and comes out below the shifter. Take it off at the tank and blow air thru to make sure it's clear.

| re: only runs with choke
Well we found it and it is so stupid i cant believe it but here was the problem: part number M127231 (Restrictor) some dumb orange cap in the intake from the frame to the air canister) looks like mice chewed it up so the hole was too big (no longer restricting). when we first saw the cap i thought - why would someone put that in there and then my neighbor pointed it out in the parts book. we put a makeshift (temporary) restrictor in its place and whadda ya know runs normal now.
Thanks to all of you for your help, especially Gator - dude you are a godsend to this board. Your knowledge and willingness to help is greatly appreciated, THanks for taking time to stick with me on this helping me diagnose along the way - Thank You
I am so glad I found this board, would have been lost without it. You guys Rock !!
I have a attached a pic of the offending part - hopefully this will help someone in the future.
