Ok

This all on me .... As Jack would say...

USER ERROR !!!!!!!

Got a new engine. It is shipped with a little rubber cap on the fuel nipple and on the nipple on the diaphram plate.
Nice touch really.

Removed the cap on the fuel nipple to install fuel line.
Forgot the cap on the diaphram plate..... LOL

Engine was very hard to start. Needed choking like it wasnt getting fuel. Yet fuel was dripping from the carb.
Once running, it would run great above half throttle.
Below half throttle the engine would load up and eventually quit.
Then it wouldn't start. It would pop and pop and pop but would never start until you choked it for
even more fuel. As fuel is pouring out the carb.

Then because it was running so rich. I started screwing in the low needle. Went all the way to closed and fuel would still run out the carb and the engine would load up and quit.

At that point I figured I had a bad carb. Went to take the cowl off and remembered that stupid little rubber cap. Did I take it off ???? Could that cause this?

Reached into the cowl and sure enough. Pulled the cap off and then tried starting the engine again.
Started on the first flip and sat there idling like it was a well broken in engine.

well It could have been broken in for all the flipping I did on the prop LOL.

Did 4 flights on it after that. Ran mint. Went out today and did another 5 flights. Sweet.

So basically. With the rubber cap on there. The air expanded once hot and pushed the diaphram down. Causing the float needle to be fully open. Explains the fuel pouring out of the carb and the engine loading up and quitting.

Cheers

If only I did not have to entertain relatives today sure would like to get some airoplane flights in, CG balance, trims & of course skill level.

Re: The never ending engine thread, East-West

This is not engine related but on an electric motor. Finished a 59” Slick build with all necessary electrics & settings. Had Lorne take it up for a test flight & not far into it the spinner/prop/housing vacated the plane. Lorne successfully landed it even thou the CG changed dramatically in mid flight. After some searching throughout deadfall & grasses found the missing parts. What I had forgotten to do, on the backside of the motor shaft a collar with retainer screw, which was still in the motor carton. The C-clip on the shaft alone was not strong enough on its own.

In reading this. I was there. I believe what Peter is sharing, is that the set-screw collet was important, under thrust. But nice to have it now, in the re-build (of sorts).
Hey Peter might you drive to the Trout Farm tomorrow? (2hr drive for him)
I might go flying.

Yeah Mike,

He dropped over to show me the carnage. Too bad he didn't get a chance to even fly it.

Regards,

Dennis

Dale, Do not think it will happen, as our company will not be leaving till mid-day. I need to get out there before months end to try out the Eagle 580 that I found in Lorne’s storage shed. I think it will be a slow flyer, but that is fine, slower impact, less damage.

Pete

PS: thanks for clarifying my post!!

Re: The never ending engine thread, East-West

A bit of user error on my end also!! Got 3 more flights on the 126" Carden / GP176evo yesterday and on the last flight a massive rattle developed so I killed the engine and dead sticked it in. All 6 prop bolts sheared off and the only thing holding the prop on was the TruTurn spinner, LOL.

Spinner is out of round, prop has been chewed up by the spinner and the sheared bolts mangled the hub.

Not sure if I forgot to tighten the bolts or perhaps I over tightened them ?

I sent Lorne a note and offered to buy a hub. Lorne called Fergie and Fergie is sending me a new hub direct with no charge

A huge to Lorne and Fergie. Customer service at it's finest
