CRRC Pro GF26I

[Jedijody]

One plug or the other does not help it start easier, different heat range relates to the ability of the plug to transfer heat from the firing area of the plug to the cylinder after the engine has been warmed up. If your having trouble starting, try increasing the plug gap to about .028"-.030".

thank you for your message but can you explain it to me??

Hello everyone have received great information from all your input I have a CRRC pro gfi26 that will be going into a CM
Yak 54 140 might be to heavy for 3D but I hope it should ok for aerobatics and sprited sport flying any comments or recomendations would welcome

After 20 flights my 26 with a JXF 17x7 (40:1) got 7600RPM @ 2500FTs.
Is it good?

[Jedijody]

That sounds about right, keep doing what you're doing.

My engine has developed a tendency to misfire at high idle and full throttle. Nothing has been changed (same needle setting, gas, etc.) I have found that re-tightening the spark plug cap kind of solves the problem momentarily but after a while the cap loosens up again. I tried a hose clamp but that does not seem to work. Could the spark plug cap/wire be defective?

[Jedijody]

Not likely, try repositioning the clamp at the very bottom of the plug cap and tighten it tight. the cap can be replaced if it's been damaged, the high tension lead cannot.

[joseae]

I will try that on Monday. How can I replace the cap if it is damaged, and what exactly do you mean by the high tension lead?

[Jedijody]

The high tension lead is the spark plug wire.

To replace the cap, carefully cut the shrink wrap off and slide the braided shielding up the spark plug wire out of the way, remove the spring retaining ring from the end of the cap, bend out the tabs holding the cap halves together, remove the metal cap halves and silicone boot. Replace with like parts in reverse order, use some rubbing alcohol to lube the inside of the silicone boot so the plug wire and spring on the end will slide in easy.

Hi guys
I have just recently purchase one of these engines and was running my third tank throught it when it just stopped. I can't get it to go again. My battery for the EI is full and when i take the plug and re-connect it i can't see any spark. Also when i used to turn the power of to the EI i could hear a click on the unit now thats gone.
Has any one had any troubles with there EI units???

Have you tried a different plug yet?

Need help!
Day after day my engine is getting difficult fo start up and tune.
For the first start up of the day I have to flip It for about one hour and at each flight I have to adjust the carburetor.
When I'm flying I'm noting a noise like if the engine was turning a unbalanced propeller,as the engine was vibrating!
Examining the engine I noticed a leak on the front bearing(PHOTO).



May be this my engine's problem?
Many thanks!

[Big-Mo]

Oh Yeah that is most definitely a problem sounds like the seal/bearing in the front of the motor is shot. causing it to suck air and vibrate i bet if you grab the crankshaft and wiggle it from side to side and up and down that you find a bit of movement,

But Jody can answer this much better than I .

Other than this problem how do you like this engine? and how old is it ?

thanks
Big Mo

[Jedijody]

I think Mo hit the nail on the head, looks like a problem to me! If this is a new engine, send it back to the dealer you purchased it from for warranty repair.

Just purchased this engine and received it yesterday. My first gasser! Has anyone put this in a Funtana 90 or a Seagull 540 Edge 60 size? Have a 125 4 stroke in the Seagull and the Funtana had a 100 4 in it.
Any help you can send my way would be most appreciated.
