Anyone know how to hook up the RCEXL CDI and sensor with this engine? i thought i did it correctly but its not working, when i trun the prop i get no spark only when i disconnct the battery from the cdi? any pointers,manuels o videos?

Check that the sensor isn't upside down in the mounting bracket. The sensor has to "see" the correct polarity.

its not up side down for sure, it can only sit one way in the mounting bracket, im sure that part is icorrect

I wrote this for another guy, it may help you.
Get Pennzoil, run it at 32:1 all the time.

Do check the timing, here's my way:
The easy no math timing.

Cut a strip of paper 1/4" x 5".

Rap the paper around the prop drive, back by the crankcase where the magnet is. Overlap the paper then cut with a #11 blade cut though both layers of the paper.

Now you have a piece of paper the exact circumference of the prop drive.

Cut it in half, take one of the halves and cut that in half again, take that and cut it in half also. Now cut it so it's in 1/3 and 2/3 pieces.

The 2/3 piece is how much before TDC the engine should fire, (30*).

Now find TDC by removing the spark plug, then sticking something in the hole, a pencil works fine. Move the crankshaft until the piston. is at the top of the cylinder, you'll find that about 5* either side of the TDC it doesn't feel like the piston is moving. Wiggle the crank back and forth until you can find the center of this piston not moving zone, that's TDC.

Now with a marker make a line across the edge of the prop drive onto the crankcase, it doesn't matter where, just that it's easy to see.

Now turn the prop drive clockwise a distance equal to the 2/3 piece of paper.

Plug the ignition into a 4.8v battery, and turn it on.

Now with the two screws loosened move the sensor off the magnet until you hear the ignition pop.

Tighten the screws for the sensor down, then confirm that the timing is still set that 2/3 piece of paper before the TDC mark.

You may have to lengthen one of the grooves in the sensor mount to get the timing correct.


1.Start the engine, set the throttle so the engine is going 3500 rpm.

2.With the engine running I turn the "L" needle in, it is always the needle that is closest to the engine, when the engine speeds up to 4000 rpm I adjust the throttle to bring it back to 3500 rpm. You keep repeating this step until your engine doesn't speed up anymore when you turn the "L" needle in.

3.Turn the "L" needle out 3/16th of a turn.

4.Open the "H" needle 2 turns out, open the throttle all the way open. Now slowly turn the "H" needle in the engine will increase in rpms. Turn the needle about 1/16 at a time, when you get no more increase in rpm the "H" is set properly.

5.Set you idle speed with your throttle trims, it's best to take the idle stop screw completely out, you should have it so the idle is correct with the trim in the middle, and the low trim kills the engine.

6.With the engine running at the idle speed that you fly at you should now be able to snap the throttle open and the engine quickly speed up. If it just dies, turn the "L" needle out 1/16th of a turn, repeat this step until is quickly speeds up. If when you snap the throttle open it stumbles then speeds up turn the "L" needle in 1/16th of a turn until it cleanly and quickly speeds up.

7.Close the hole or notch up in the choke plate, I'll post a picture of what I mean, I do it with soldiering the hole close, some use glue or a bolt.

After you modify the choke plate the way to start the engine is:
a. Close choke completely.
b. Open throttle half way.
c. Flip engine with ignition on until the engine coughs.
d. Take choke fully off.
e. Set throttle just above idle, flip until it starts, usually 3 to 5 flips.

You have to use the Rcexl sensor, the CRRC sensor is not compatible with the Rcexl module and will give you thefault you have and as Rich mentioned the sensor must be positioned with the proper polarity, here's the instructions.

my misteak its not a rcexl sensor, its what ever came with the ccr 26cc engine

There's your problem.

issue solved ThANKS ALL!!!

What was the problem?

The RCEXL ignition module will not work with a CRRC 26 ignition sensor?

the problem was infact the sensor was upside down and not centered over the magnet![:-]

still cant get this engine to run, it will make a popping sound when the choke is on and then i take the choke off try to start it with my electric started and all it does is pop,spin spin spin and pop...never runs..anyone know the factory high speed needle and low speed needle settings?

could it be the spark plug? i checked it and it does still spark, but it has a oily black ring around the threads

First stop using a starter you are flooding the engine.

2 turns out on both needles is a good starting place.

Take the plug out, dry it off, put it back in.

Hand flip it with the choke on, throttle 1/8th open, if you haven't plug the hole in the choke plate, puy your thumb over the intake as you flip.

Once it pops once stop take the choke off.

With the throttle 1/8 open flip it over, it should start within 5 flips, but if you flip 10 times start over with the choke.

hmmm... i will try that do you think i need a new plug?

The factory needle settings are, L 1-1/3, H 1-3/4. You can try a new plug, for an NGK it's the same number as the Torch that comes in the engine but if you are still using the CRRC sensor, do yourself a favor and replace it with the Rcexl.

iIt has a Rcexl ignition set up, i just need to know the timing and it came without instructions..anyone know where i can print off one of thise time setting things?

30* BTC

Please read the instructions that I posted, they don't help if you don't read and do them.

IMOthis method is much eaier to do, degree wheel is included, shoot for 28 degrees BTDC.
