a little wet from me trying to start it.

compression is also good, i took the head and cylinder off yesterday just to be on the safr side every thing looked fine to me no scoring and rings look good.

If you have Good compression A correct and uncontaminated Mixture.

And their are no air leaks With a correct operating exhaust .
We need to focus on spark plug..And wire.kill switch.
CDI & mag.

You did disconnect Kill switch and tried....correct.?



Also you may give Us A call .( this typing is getting old) LOL

I know the Motor kit wasn't bought from me but i don't mind helping at all.


cheers

You seem to know your Poop.
If the Motor runs on Starting fluid Low compression is not yet ruled out. air being sucked by the crank seal will give a high Rev symptom as well.
recheck manifold gasket..


It sounds Like A Air leak ( might be coming from crank ) .

Ill keep thinking.
Let me know the outcome.

Blur Collar - I'm new to MB's but have been around IC engines for many years. Here's something I learned from my 2-stroke outboard motor days - using starting fluid (usually ether) washes lubricant from the exposed surfaces and can contribute to unexpected ring and cylinder wear; for 2-strokes it was always recommended to use a spray bottle with the proper gas/oil ratio to inject a test starting mixture. Do you think the same issue would apply with these motors?

BTW, in this case I would have guessed intake manifold gasket... but didn't think about the crank seal. Not something that would have been an issue on outboards. Good place to look. If you can get to the crank seal while running, spraying some 2-stroke oil on it will make a temporary seal, if idle drops to normal briefly, you know it's sucking air.

found it it is the crank seal the one behind the primare drive gear. pulled the clutch cover off and put my hand by it as i was peddling puff puff puff right out the side.

Bummer..

Wish i was wrong.
I never had to replace one on the china Kits.
Like i said on the phone .I ran into this a million times On older 2 stroke motors.
It will not be an easy fix But it can be done.

Sorry i don't carry any Seals ..

If i did i would mail you one out for free.
Try getting a hold of the original motors vender.( BGF)

Crank seals can go anytime But having only one months On the BGF motor maybe he can give you a Kit or long block for cost.It never hurts to ask.

Good luck

Cheers

Using Starting fluid can be very bad for a motor.I don't like it at all.
But in situation like this It can pin point a Problem very fast.
AGAIN
using starting fluid id a bad thing..
Buy to a trained individual a small amount under certain conditions Will be fine.

Crank seal just went over night and that seems strange to me. I'm milking my break-in on my first HT and am learning alot from you guys!
For what it's worth, thanks ALL.
