A washer will push the whole assembly up into the bottom of the clutch bell.

Whatever you're doing you're doing wrong, you dont need and shouldnt use red locktite.

Is your low end rich and the motor is kicking?

@ Barracudahockey Yea, something sucks. Let me take a picture of the carb tonight, cuz I dont know which needle is which. It has a funky carb ive never seen before, along with a strange head that has two glow plugs..

Here, I got a couple picks of this two needle set up that im not used to. and has anyone ever seen this kinda head?? Mabye I need some tuning tips on the strange carb and head set up??

So far the nut is holding, but is does seem to be poping funny when turning over...

Thats a 3 needle carb that allows you to adjust the midrange mixture, and the head is called a Viper head, you light one plug and start it, when you pick it up into a hover you will hear the second plug light and the engine smooth out.

No $H!T. thats cool. This is new to me. You dont happen to know which needle is which.
Would these have different default setting than stock? My raptor 30 is much simpler than this one.

Best to get the number off the carb but going by memory, the one where the fuel comes in is the high speed needle, the small screw is the idle mixture, and the needle farthest from the fuel inlet is the mid range.

If its the carb I think it is, then the mid needle is opposite, its an airbleed that you open it to lean the mid range.

Sorry to hear about your sex life. Yes, there is a number stamped on the front of the carb, 60L for example, you're going to need that since this is a custom (frankencopter comes to mind) installation.

Got another question! I got the clutch to stay tight on there, and the carb model & tuning specs figured out. Got her idiling, kinda ruff, and I noticed the clutch seemed to be engaging early. Sprung Clutch!!

Now my question, I Have an extra 90 size clutch sitting around, will that work in a 50??
my guess is the extra mass of the clutch is going to make it engage too late, or higher RPM's ??

Is this a "new" symptom?

If the clutch shoe has a crack in it, then you have some issues. You will need to replace the clutch shoe, before you fly.

If the clutch liner is to thick, then no problems. It will wear in. a couple of quick taps on the throttle will wear it in quicker.

The 90 size bell housing liner is thicker than the 50. I don't think that it will work.

Old Guys Rule!

@Zaneman007 its a new/used heli that im unfamiliar with. Mostly just the motor. I've crashed and rebuilt my electrics plenty, so im used to that. My other only nitro is a Raptor 30 that ive flown for 4 years and have never had to pull the motor yet. so this 50 and the clutch issues are little new.

The gap on the clutches i have here are either obviously smushed in( the one the heli came with in it) or very sprung out ward (wasnt like that when i put it in) I only have about ten mins. or so on it, it was used.

I think your right, I might have to wait for a new clutch to come in.

Thanks man...

If the clutch is sprung (the gaps between the shoe and the body aren't parallel) then bending them back will only last about 1 flight.

The gap needs set correctly when the liner is installed and a new clutch used or you're going to be going back and forth replacing parts.

Alrighty, ordering a new clutch. Lack of patience makes people think strange things....
