1. I read somewhere that they suggested using a CJ8Y spark plug instead of the CJ6Y in the StrikeMaster Lazer Mag Express because it supposedly sparks better. The manual calls for CJ6Y, can anyone confirm that I could/should use the CJ8Y? On the StrikeMaster web site it lists both but the CJ8Y says 2hp Techumshe (TC) and the CJ6Y says 2hp Techumshe (TMO).

2. When you buy spark plugs are they already gapped and ready to go or do you always have to adjust them?

I personally would recommend neither...go to a marine dealer, ATV shop, or an auto shop and Cross reference the CJ16 over to a like NGK..a better plug.

If you go to the NGK web site you can look it up for yourself if you wish.

Gap should be set as long as you do not alter it.

Im cant remember for sure but i think its a hotter plug than the 6. I forgot how the heat range works with champions.

I would stick with what strikemaster calls for, putting the wrong heat range in can cause damage.

Also, make sure you check the gap. Having worked at a auto parts store I can tell you that plugs' gap should always be checked. The way stuff gets banged around in shipping and in the hands of some employees stocking, its amazing that they dont come broken half the time. *Always check the plugs before you pay for them to make sure they aren't broken*

Higher the number, hotter the plug for Champions. Just the opposite for NGK.

There's no reason you should need to use a hotter plug if you are mixing the fuel correctly.

I would agree with changing over to an NGK plug. Bosch also makes good plugs, not sure if they make one for this application.

I have been running the CJ8Y in mine for a while now. It burns one step hotter than the CJ6Y and runs great. Cy up at the Strikemaster shop will recommend the CJ8Y. My buddy was just up there on Thursday evening and they put the 8 in for him. I don't know why they put the 6 in from the factory, but the 8 does work better.

Because the auger is run for very short periods, in cold temps, and normally not warmed before you start cutting, using a hotter plug isn't going to hurt anything. In fact because of all the above, you'll probably have less carbon build up in the engine and less plug fouling if you use a hotter plug.

What about those "Pulstar" plugs. Are they the real deal? They claim more power and efficiency. Thought I saw them at Menards among other places.
Don't waste your money. I think they would fall into the "Deer Whistle" category. I can't see how a spark plug can increase your horsepower unless you are replacing a worn out one with a new one. If all these "miracles" were so great the manufacturers would be fighting over them. Just my opinion.

Still running the same NGK for 3 years now without need of replacement in the old mag III. The motor had trouble starting and running under load when I acquired it and all that has changed is the spark plug and the addition of amsoil saber to the fuel mix. She's been running strong ever since. Better and more reliable than my buddy's brand new tough to start jiffy stx.

Yup...I'm on that NGK wagon too.

I roll-slide-drill with the NGK BPMR7A plug, better plug, hotter cleaner spark.

*BPMR7A NGK Replaces Champion RCJ7Y, AC CS42S, Autolite 2974,

I also always run Sta-Bil Marine Blue Formula in my fuels, and run high octane fuel.

      It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.

      Problems with Yetti

      By rundrave · Posted

      we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.

      I haven’t done any leaf springs for a long time and I can’t completely see the connections in your pics BUT I I’d be rounding up: PB Blaster, torch, 3 lb hammer, chisel, cut off tool, breaker bar, Jack stands or blocks.   This kind of stuff usually isn’t the easiest.   I would think you would be able to get at what you need by keeping the house up with Jack stands and getting the pressure off that suspension, then attack the hardware.  But again, I don’t feel like I can see everything going on there.

      Problems with Yetti

      reviving an old thread due to running into the same issue with the same year of house. not expecting anything from yetti and I already have replacement parts ordered and on the way.   I am looking for some input or feedback on how to replace the leaf springs themselves.    If I jack the house up and remove the tire, is it possible to pivot the axel assembly low enough to get to the other end of the leaf spring and remove that one bolt?   Or do I have to remove the entire pivot arm to get to it? Then I also have to factor in brake wire as well then. What a mess   My house is currently an hour away from my home at a relatives, going to go back up and look it over again and try to figure out a game plan.           Above pic is with house lowered on ice, the other end of that leaf is what I need to get to.   above pic is side that middle bolt broke and bottom 2 leafs fell out here is other side that didnt break but you can see bottom half of leaf already did but atleast bolt is still in there here is hub assembly in my garage with house lowered and tires off when I put new tires on it a couple months ago. hopefully I can raise house high enough that it can drop down far enough and not snap brake cable there so I can get to that other end of the leaf spring.
