    How to tell if it's a MKIV
    What are the things to look for? How do I tell if it's a MKIV vs others?

    I've never run "wot" straight and level because it (the tach) reads 8000 rpm on the climb out as soon as I get to 400 or so agl I back off to just under 6000 rpm indicated, God only knows what it's really turning. the egt's have never hit 1100 the cht's always under 300. plugs look good not hot and not fouled, changing/ re-gapping did not make any performance difference. I think the engine runs strong it's just I've been afraid of running it because of the tach readings. Static max fluctuates thus the reason I started the thread. I admit I'm a newbie to 2 stroke aircraft engines but I'm not a dumbass, i.e. I fly with both mags/ I monitor my egt cht readings,/ I even do a mag check during my run up. Realize I'm in phase 1 testing on this plane and it has 17 hrs, 8 of which I've put on it. With out a local resource to give me a what's normal I've just been trying to carefully test the characteristics of this experimental, the biggest hang-up has been the issue I started the thread about. I appreciate all the advice do you think there might be something else besides the tach that could be the problem?

    I re-read this and I come off testy, well I am at work and I haven't flown since dec.27.

    I always run both mags while flying! All the tests were static run ups, and you are right my egt's were real nice although I never really thought about that being a symptom, thanks for the tip. I wish I had found this site months ago!!

    Yep sounds like you've been there, it is a needle type electronic VDO tach, if I change it I'll spend some bucks and get a MGL flight 2, the original intruments are used junk,(i'm not the original builder) it's time to get serious and make this thing right, and nice. Also I'm Looking at an Avid MKIV kit I hope to get it this spring!
    I plan on using You guys as a resource, I'll let you know about the tach when I get the new one installed. thanks.

    Rotax question from a newbie
    Hello all, I've read quite afew posts on here and thought I'd ask a question that no one has been able to really give me a good answer to. I have a rans s5 with a rotax 503 dcdi the tach looks like it is reading over revs from the engine, thus leading me to overpitch my prop, ect. The deal is if I run both mags the engine looks to over rev even with a fixed pitch Tenn. wood prop made for the 503.( they said no way it would over rev, same story with powerfin) If I run the left mag it still over revs (or it looks like it on the tach you really don't hear it over rev) Now comes the weird part if I run the right mag it looks normal at the high rpm range at idle it reads zero, literally, the tach starts to respond at about 2500-3000 rpm and then seems normal, then engine runs better with both mags though the rpm range and runs ok with either by themselves. if it's a bad connection (I've checked the tach itself) why only one mag? could the tach be bad? if so it sure is weird, I was leaning towards the left mag/CDI is creating dirty signals and screwing up the tach if so why does the other not read at idle? Any thoughts?

    I've made some offers on barnstormers but that seems to piss them off, I guess they think they have them priced low enough as they are, strange bunch we are sometimes. I have a rans I'm flying so I'm not desperate just would rather build a nice 2 seater that i want to keep. I'll keep looking. I enjoy the posts on here, makes me jelous, I fly alone
    mostly, but it's still great!

    Hello, not much on introductions but I'm interested in an Avid Mk 4 or a kitfox 4, I've been lurking here for awhile, trying to learn, would you care to part with one of your kitfoxes? I've been looking for a good one preferably an unfinished kit on barnstormers and there just too pricey when you don't know what you're getting.
