Never seen priming a gas engine done like this before. It scares me just watching it!

No big deal, just don't let go of the prop. Rocking it back and forth primes the carb, and a slight kick tells you it's ready to start....

I'll just take your word for it.

I just rock the prop till wet, then power it up, then flip. Makes me feel a littler safer.

Thats proper starting procedure other that hanging on to the prop. FLIP the prop all the way thru till it pops, then bring to idle and she'll start just about every time.

If you hold the prop firmly, the kick is just a bump.

If the guys that question this way of starting a small gasser.....it shows they do not have much experience at all with engines. Get to learning....Fellows!

I've seen many people prime large gassers by rocking the prop. The only problem i have with the techique shown in the video is reaching across the prop arc to hold the plane. Get someone to hold the plane for your. Keep the arteries out of the danger zone.

Joystick is a regular RCU contributor and usually hangs out in the Syssa 30 thread.

The technique he shows in the video is more or less the way Todd Syssa does it. Todd had the first vids I saw of someone doing it this way.

He is a member of the club I joined. He is very methodical and safe in what he does. Plus he is a nice guy.

i have a buddy that starts his engines that way, it always makes me pucker... theres no way i would start a gas engine engine that way.... it may be safe to the seasoned experts, but ill stick to my traditional style

Me too, he can and does do it successfully, but I prefer the traditional method.

I watched it four times. Is he back flipping the prop against compression to start it? If so, I don't understand how it works as it doesn't seem like a back flip against compression would hit the point where the ignition fires on a gasser. It's early for me, only had half a cup of coffee, am I missing something?

What he is doing at the field is turning everything on and the choke in the choke/on position. He then grabs the prop firmly. Then he turns the prop back and fourth through the compression stroke forcing the diaphram to pump. He does this till there is enough fuel to ignite and pop in his hand. Since he is holding on "really" firmly the prop does not get away from his control.

Then the choke goes off and it "usually" starts on the first flip ( turning the prop in the normal direction ) with the choke off. I have tried it on my DLE30 but frankly it makes me a little nervous so I stick to the conventional.

The carb is a pumper carb. So rocking the prop back and forth will draw fuel. I perform this procedure on my engine but with the ignition off. I have an optical kill switch and verify ignition is off before priming the main fuel line. After I see fuel enter the carb through the tygon tubing. I flip the switch on my transmitter to arm the optical kill switch. I also have a servo actuated choke. I flip the switch for that as well. Then start the engine in a normal manner. Our field has starting benches with vertical uprights. We also have a tail hold down that is anchored to the cement for the large scale aircraft. That is where I prefer to start my plane from.

Like most here, I've found rocking the prop to be a tremendous help in starting a cold engine.

My technique: IGN off, choke on, throttle full - then rock prop for 10-20 seconds or so. Then IGN on and throttle idle with choke still on.Flip againuntil it pops(usually in the first few flips if not the very first one), then choke off and flip till it starts. Pretty safe and easy.

I don't really see any gain in rocking it with the ignition on. The least slip up or carelessness and it could be for a bad day.

I found after the first time statring my DA 50 swinging that 22X8 wood prop, I needed to change my shorts.....

It scared the heck out of me....[X(]

I have seen this method used and this guy looks like he knows what he is doing.....

Always a puck factor for me still new to gassers........

I think the scan rates and the You Tube video causes an illusion? There's just no way he was back flipping to start the gas spark ignition engine?

av8tor1977

My Feedback: (6)

Well, that was my question.

Hell, there's nothing new about rocking the prop back and forth on a gasser to get fuel to the carb, nor is it a new thing to hang on tight to the prop while turning it to feel when it has the right amount of prime or choke. It just looked like he back flipped the prop to start it and I can't understand how that would work with a gasser.

I just looked again at the video and on my computer it appeared that he flipped it conventionally to start it.

I started flying gassers in 83, the first gasser I had was a Q35 with no choke. You had to stick a finger in the carb ans rock thwe prop just likr in the video. Once your finger got wet, it was ready. Its not that big a deal. Looks worst then it is

With the standard choke on, ignition on, flip till it starts then stops, then choke off and flip till it starts you are actually flooding the engine a bit. That's why it takes several flips with the choke off to get it going.

On my airplanes without cowls, I do just as you suggested; I put my finger over the carb and flip with the ignition off until my finger gets wet. Then turn the ignition on and it nearly always starts on the first flip.

I may be new to gassers, but I really doubt that engine is going to fire with the ignition off......just my thought.

I personally use the Kavan starter every time....Yea I'm a chicken like that...but that Kavan turns the Evolution 40GX like it's a little .049

Willing to bet the Kavan can start some big gassers.

I think it is to keep from cutting his fingers on the sharp throttle stick.
