My four stroke engine which was installed on my funfly still making me hell of the time and was sent back for recheck.
I have an old os 46fx which i would like to i install temporarily till the engine will be fixed (few weeks).
The problem is that OS engine holes are located differently then my 4 stroke .
Can i have two sets of open holes at the same time on my fulyfly or does somebody has a better way to that.
i really don't want to wait all this time

need help
thanks
