I have a Giant big stik. I have a CCRC 40cc engine on it. Runs great, is a awesome plane. I am new to the gas, 2-cycle planes, so still trying to get better at getting it started.

Well today went to start it for a freind. What I do is leave the ignition off. turn on the choke ,flip the prop about 6 times. then turn on the ignition, flip it until it fires, then choke off and flip till she starts. Is this right? Thing is it does not always start that easy. It also does this thing where it like does this fire/pop real quick and catches my fingers. Like it has to much gas or something in it when it ignites? It is hard to describe.

Well long story short. I flooded the engine, how do I unflood a engine like this? Any one have this engine.
What is the best, and easiest way to start one, expecially this CCRC 40cc.

Thanks
George

Anyone ever flood one of these?

Easiest way to cure a flooded engine is to remove the spark plug and with the choke off and with the plug hole pointing down flip the prop a couple times to clear the excess fuel from the cylinder. Maybe flipping the prop six times when choking to start the engine is too many and that is sending excess fuel to the engine. Try changing your starting routine by choke on, ignition on and throttle set at a high idle, then flip prop until the engine pops, then choke off and flip until it starts. It is somewhat unusual for the prop to want to bite you if the engine is timed correctly so maybe you should have the timing checked which should be at 28-30 deg BTDC.

how the heck do you check the timing on a engine like this?

George,

Follow Karolh's advice.

If the engine is not inverted, it will take more turns for the fuel in the crankcase to be vented out through the opened plug.

In my experience, full open throttle during cranking also helps venting the excess of fuel or flooding.

Wear a leather glove for flipping propellers powered by a 40 cc.

The engine is inverted, and I wear multiple gloves lol When it is running it runs good, so I do not think it is a timing issue.

with the ignition off. when I am "priming" the engine the choke should be on right? Should the throttle be opened up?

Thanks

Full throttle, ignition on, when it pops/fires, choke off throttle back to idle. It should start on the next flip. Make sure you have a good sparkplug and gapped at .020

When is this EVER a good idea?

I wondered this also when I read it. Seems dangerous.

The full throttle part is the problem. Crack the throttle one click or so, ignition on, choke on then prop til it pops.
Works fine, lasts along time

Made me wonder if I had been doing it wrong all this time, guess not.

Many flyers run the fuel out at the end of the day, do you? If so do not confuse priming the carb with priming the engine. If the carb is not dry, never prop the engine without the ignition on and you won't ever flood the engine.

If you completely run the carb dry, the next start is always going to be alot more cranks on the engine to first prime the pump and carb diapham. Again once fuel is in the carb never prop without the ignition on and you won't flood out the engine (throttle position should always be appropriate).

I used to get the same issues, the way I fixed it was no longer priming the motor. Ijust leave it on idle, put on the choke with ignition on and flip till it fires. It may not fire on the first 2-3 flicks but it wont flood and it will only take around 10 odd flicks at most.

I recommend you check the timing. I have a CRRC 26cc that was set at 50 degrees btdc and was a bear to start and ran hot. Re-timed to 28 degrees and is well behaved now.

Well this motor was used for a season before I bought it. It is all broke in. My probem is being new to this type of starting method. (used to a pull start) Once I get the steps, down I think it will be fine. When I have t running it runs great. Starting was my problem.

How do you check the timing on a engine like this? Where should the timing be?

Thanks
George
