I have a jamming x1 crt and the stock engine...I believe is the OFNA hyper .28 big block...anyways last time I ran it it would just bog out the whole time and I noticed a gas leak...I took the body off and hit the gas and watched fuel fling out of where the clutch is...I'm not sure what to do or how to fix the issue I pulled the engine out and took the clutch cover off but that's as far as I've gotten..please help I can post pics on request

Hey buddy. After reading your post i can think of two things that could be causing this problem. The first thing it could be is a hole in either your fuel line or your fuel pressure line. It may be squirting fuel out, throwing it on the clutch bell and making it aeem as if its coming from the clutch area. Check all of your fuel lines and fuel tank for any possible leaks. I would do that first. If everything there checks out fine, the second thing that could be causing this is a bad front bearning in the engine itself. The bearning im talking about is the one located directly behind the flywheel. These bearninga have been known to "spin" in the engine casing. If this happens, the seal between the bearning and casing can become unsealed and the pressurised engine case is pushing the fuel out of the weakest part of the engine, in this case would be spitting it out of that front bearing. This would make it seem as if the fuel was coming front the clutch as your described Either problem will cause a lean engine condition, starving the engine of fuel. Im sure it has been running hot as well due to this lean mixture. To change the front bearning is a simple job, i recommend using a heat gun to remove the old bearing. Also, to install the new bearning i would dreeze the new bearning to shrink the metal and put the engine case in the oven at 275 degrees. The new bearning will slide right in and when both pieces cool down to room temp, a nice strong seal will automatically be made between the new bearing and the existing engine case. Good luck with everything

If you are sure that the fuel is coming from behind the flywheel, then it sounds like a bad front engine bearing. Not too hard to replace. But without some experience, it coud be dicey.

the engine could just be extremely rich and pissing fuel out the front bearing......

I agree.

Is the engine new?

It seems to me if the front bearing is leaking fuel that may have been caused by a rich engine setting, that bearing should be replaced. Two stroke engines run off of crankcase engine pressure. In order to have a good smooth running engine, that crankcase pressure must be continuous and even. Any air or fuel leaks will affect the engine negatively. This is why a new engine runs better than an old one, crankcase pressure is maintained throughout the two stroke process, both positive and negative pressure  this is also why a good piston/liner seal is imperative to smooth and strong running. If the front bearing seal has been compromised it is time to replace it. Leaning the engine out to reduce fuel leakage is amateur. If leaning out the mixture reduces the amount of fuel coming out of the front bearing it will then push air out thru the front bearing in place of the fuel which is not good either. Replace the bearing correctly and you will take care of the problem. Another thought, if your engine is running on such a rich mixture that its pushing it out of the front bearing, its probably time to replace the piston and liner as well. Good luck and if you have any questions about changing the bearing please dont hesitate

The front bearing does not seal the engine.

I call Shenanigans on this one.

I do not understand what you mean?
The post above mine implies that if fuel is leaking from the front bearing then the bearing/seal is at fault. I know that this is not necessarily true.
Please explain what you are saying?

I believe your statement "the front bearing does not seal the engine"is false.

Also, I believe DSA should elaborate on the statement "fuel flinging". Is it really gushing or just oozing. Alas, seems DSA has disappeared.

The front bearing seal is supposed to be created when the engine is running. If this seal is not made the engine will run poorly. Did you try leaning the engine out to see if that corrected the problem? Either way, i would replace the bearing. It will cost you no more than ten dollars and about 20-30 minutes of your time. Do the right thing to be safe because fuel shold not be blowing out<div>of the front bearing no matter how rich it is running</div>

I thank you guys for everything you've said...I'm using mobile and its not been letting me post

Ah right I see thanks, I shall try to explain,
I have 3 comparable engines to that of the OP (-TTR.21,Hyper.21,Macstar.28), I have had these engines from new and broke them in with a rich mixture. During break in I noticed on all engines that a fair amount of fluid was leaking from the front bearing area, however after (break in and) leaning the mixture the leaking stops or is minimal to say the least..."moist" would be a better description....and better moist than dry.
So that would say to me that the front bearing does not seal the engine.
My theory is that when running way too rich we are constantly adding an incompressible fluid to the crankcase that is not reaching the combustion chamber, the more we add the more we decrease crankcase volume, the more we decrease crankcase volume the higher the pressure (in this case it is positve pressure we are concerned with), therefore the weakest point in the chain (the front of the crank) will release pressure.
Of course the front bearing seal will play a part in sealing the crankcase but fluid leaving the bearing would not automatically say to me that the bearing is at fault.

Yes, no point just us debating....more info would definately help...he came/went but still...
