Thread: Rate my plugs!

  1. #1

    Rate my plugs!

    With the 1050 finally figured out, and the 1200 screaming, I'm just trying to fine tune them to make sure they're getting the right fuel.

    I took both out this morning and did a set of chops. I did some last week but didn't have the camera with me. They both seemed a little lean so this morning I opened them up each about 1/8 to 1/4 turn on each carb.

    Here's the 1200 in order from MAG to PTO:

    Pictures are a little fuzzy, but I'm thinking:
    M: A little ruch
    C: Good, maybe a tad rich
    P: Pretty good (maybe a tad lean?)



    1050 - Pictures are worse. Kinda hard to take pictures floating out on the lake. I need to remember to take a spare set of plugs so I can swap them and photograph the chops when I get back to shore!

    P: A tad rich


    What are your thoughts?


    The 1050 seemed to be running too hot, although the plugs don't really show this. The MAG in particular the plug was actually too hot to hold with my bare hand. Not sure what to make of this....gonna have to run through the cooling system and make sure everything's flowing as it should.

    1200 mag-rich,cen-perfect,pto,tad lean
    1050 mag-tad lean cen-more lean, pto-tad rich

    Just my opinion.

    They say deep inside the electrode is the only place that reveals whats going on. not the upper part of the ceramic on the center electrode in there.lower down into it. hard to see that from the pics.

    A nice choclate color is what I was looking for. Thats great to hear they are both running good.

    does your 1050 have a history of getting hot? i mean other 1050's get hot also? not familiar with them. Ryan has 1. See what he says about that. He had great wash on his at starved rock. maybe a tad rich but safe. perfect running ski.

    I bought the 1050 with a blown motor so I don't know how it ran before....but obviously not too well!! I 'd have to dig up the pic from when I got it, but I want to say the MAG was the cylinder that had seized and melted down.

    I need to read my old posts too. I can't remember which dome configuration I ended up using. I remember debating on whether I should go with the '96 or '97 (which used a different middle dome) but I can't remember at all what I ended up using.

    I need to find my scope and see if there's any wash developing yet.

    Maybe a rich setting on that cylinder is what ya want to prevent it from heating up too much.

    What's the piston wash look like?

    Did the RPM change with the needle change?

    Probably. I'll open them up a little more next weekend.

    I haven't checked the wash yet....can't find my damn scope. And I didn't really pay attention to the RPMs. I know the damn 1200 is a little under-propped because it would rev way up out of the hole until it finally hooked up.....but when it does, it flies!

    Are you sure?

    Found a similar problem on a SLTX.

    The impeller was totally beat up, and every one of the stator vanes had a chunk missing from it.

    Looks fat to me, just an observation. Lean that thing out a bit. Should be tan in color when dialed in correctly.

    The pump is in perfect shape. Almost new. I do have another brand new 6-vane pump and wear ring that was supposedly for a virage. I need to see what prop it has on it...
