Ok I will start by saying I found my cat was plugged....Ok! that was fixed Cough Cough! Ran much better now...Ok now for the 2nd O2. Started looking at ways to fool the sensor..Did some research on it and found a couple ways..I don't know what is right or wrong..I'm a try it and see kinda guy sometimes... So if you buy a spark plug non fouler dorman 42009 at advance.( Same Thread as O2) Take it drill it out to 1/2 on the inside of it then install in the rear. Suppose to take it out of the stream enough that it just reads enough to work...I don't know if it works or not for sure. I can say that when I did that that it idled ruff and was acting all weird like it had a bad throttle position sensor... So I was messing around with it tonight and seen my fuel pressure was looking high..Like 65psi....Took and adjusted it down and it started running worse...Go figure! So I said heck with it and started turning it up and wala the miss went away. Now did the miss go away it is unreal the crispness of the throttle! Rediculously better! I mean WOW! Woke it up!!!! Can't wait to run it on the hills! So who knows but I do know this is the best by far that it has ran since I got it!

Chime in! I just wished I had a way to compare it to another one!

Ok well Going away over the weekend but I will be checking for updates! Have a Great Memorial day! Oh yeah check out Templeton Pa of Youtube....I gotta go there...Someone here is from there but it escapes me at this moment of who...LOL Sorry....

      Utv wont start and broken fuel injection wire
      By Jeff freeman
      I have a Coleman 550.  Was having problems to start with where it would start and then shut off after a couple tries. It would take off and be good. It then got to a point where it would not start at all. I replaced the fuel injection twice the second time I replaced it I noticed a mouse or something had chewed one of the wires that connect the electrical to the fuel injector. . So two-part question first does anybody have a part number for that wire harness?  Second, any other ideas after I fix the wire harness permanently on what could keep it from starting I have gas flow up to the fuel injector.

      Massimo 500 will not start
      By JohnnyB
      My Massimo 500 will not start. I’ve checked all the obvious things. It turns over just fine. fuel, spark, fuse box are all good. I can’t figure it out. Any ideas would be greatly appreciated. Thank you.

      Landmaster LM200 Will Not Start
      By BWF
      I have a 2011 or so Landmaster LM200.  I cannot get it to start.  I turn the key and nothing happens.  The brake switch seems to be working, the ignition switch works.  The Coil is new the Voltage Regulator is new and the starter relay is new.
       
      I can connect the terminals on the starter relay and it starts right up and runs fine.  I just can't get it to start by turning the key.
       
      I am having a bit of trouble bleeding the brakes, not much fluid comes out at the calipers when I am pumping the brakes, though that an air bubble near the brake switch might make it not sense that the brake pedal is depressed.
       
      I am at a loss, please help!
