I just put a new QQ106 in service yesterday... 3 flips with choke... POP choke off, one flip.. started right up! Easiest starting engine I have ever had so far! I used the glove for the first few starts but put it away after that.

I did notice there is a warning in the addendum sheet that Bobby attaches to the manual - "WARNING - ENGINE COULD KICK BACK IF ATTEMPTING TO START IN A FLOODED CONDITION"

I'll never have that issue as I will only flip unitl the first hint of a pop. Once I open the choke, I only have about 2-3 clicks of throttle (no more) and my engines usually start on the first or second flip.

One the engine pops, I will not re-choke. Of course, it is warm here all the time, so the need to choke is minimal anyway.

I too have a 3W which sometimes kicks back, and does it hard. Mine is a 75i, with about 5 hours running, and has done it since new. I have run it with a friend's (new) ignition unit, with the same result. The ignition units are not getting hot. The static ignition timing is set at a few degrees after TDC. After a number of painful experiences I finally came to my senses and started to use a chicken stick rather than a glove. I have sent the engine back to 3W but they returned it with no fault found. It is still kicking back and I have just broken a second prop on the stick during a kickback. It is getting expensive! With the carb set to the factory settings it does not kick back, but the main needle is way too rich. With the needle set 5/8 of a turn out rather than one, the engine runs well but kicks.

Can anyone help please?

Jim,

I learned the hard way with my 3W-106, have the scar to prove it. Lean out the low end. When you get it right, it stops kicking back. I kept leaning it until my transition was smooth and then leaned out the high end. My -75i has never kicked back, but I went through three props on the -106. I went to Lowes and bought an 18" length of hose that I use to prop now. The hose is 1 1/4" or so in diameter, clear with a fabric braided into it. I believe RV's use it for waste water drains but I'm not sure. I'd post a picture but can't find the memory card for my camera (ARGH![:@])

I have a 3W 60k that has allot of flights on it . Since it was new it will kick back hard IF it is really wet with fuel or the idle is set slightly high.
I have checked the timing , had the ign module checked and replaced , it still does it .. but only if i over choke it or have it set to high idle ...
I basically had to re-learn how to start this engine ... compared to my other gassers.
Since It appears that original post has had no running problems after started, but only a kick back problem occasionally while starting I would consider
that it might be getting too wet and kicking back .

How do you guys tune the low and high ends ?

This is interesting, I had a 3W 60, 5 years ago, and it backfired once on me. Good thing I always wear a big glove because it did hurt all the same. Only did it once, but unfortunately the motor was toasted in a crash. Just ordered the 80Xi. I will give a small review of it here when I get it, and I will be using my hockey glove

Mike(Rajul),

This is what I've been doing lately when I tune the Low and High ends of my gassers: Factory settings, then, lean the low end first. (I didn't always do this, used to start at the high end, but with the kick back issues, went to the low end). Lean it until it almost quits, then richen about an 1/8th of a turn. Lean the high end until you're 200-500rpm of peak. Depending on the engine, it can be either a long or short process. Fly the airplane. I'm sure others may have better ways, but this works for me.

Thanks everyone for the replies. I thought the settings I ended up with were pretty good, with a good pickup. There may be a little scope to lean out the bottom a little more and compensate on the main needle, bit not much. What I don't understand though is why it hasn't been kicking back with the factory settings, which has the same bottom needle position and a richer main needle. If being wet was a problem, wouldn't these settings make things worse if anything? Dan767, thanks for the hose pipe suggestion.

Jim----My smaller 3w kicks back when too lean and never when slobbering rich. It also helps if you flip the prop like you mean it, the only time it bit me was my fault.

When most of us start our gassers, it's common to advance the throttle slightly, choke and flip. With the choke on and the throttle up more than just a click or two, it can get real rich (wet) in a hurry. The only thing that I'm doing differently, is leaving the throttle at idle, instead of opening it at all, even when I start for the first time of the day. It takes two or three more flips, but it doesn't seem to get overly primed, and starts just fine. After the first start, most of the time I can restart without the choke, unless it's been more than 20 minutes or so.
