PLEASE HELP IF ANYONE HAS EXPERIENCE WITH THIS :)
I have a mark III classic w 912 uls Acting odd during taxi needs lots of left rudder
to keep on the runway with tail on and off the ground and while flying needs
lots of right stick to keep plane level. If you let go of the controls during
straight and level flight the plane wants to roll to the left has anyone
had similar experiences and or has anybody had any luck with adjusting engine
mounts changing the thrust angle to help with aileron trim etc

A Kolb with lots of power does take a bit of rudder to keep it flying
straight. Most people add a trim tab to reduce the effect.
A Kolb that wants to roll right or left is a plane that isn't rigged right.
The common cause is the wings aren't flying with the same pitch or angle of
attack. Kolb sells a wide aft wing attachment fitting that allows one wing
to be adjusted by moving washers around on the attachment bolt to trim out
minor alignment issues. Use one on both wings for more adjustment. Some
people add a bungee cord that pulls the stick to the side. I trim my plane
for neutral stick force flying solo but requires a bit of pressure with a
passenger. Kolbs are almost never able to fly hands off.
As usual worth what you paid for it.

In my very limited experience with this particular aircraft, the issue of it being
"out of trim" or "out of rig" is the lesser of the problems.
An aircraft with adequate primary control authority can be flown, tested, trim-tabbed,
adjusted, bent, hammered, shimmed, tweaked, and "figured out" until it
flies correctly. Like a car that "pulls" to one side, it may be somewhat annoying
to drive but it is not unsafe.
An aircraft that does not have sufficient primary control authority to adequately
overcome the other (relatively minor) issues cannot or should not be operated
until the source of the control problem can be identified and corrected. Essentially
I believe you have to be able to maneuver the aircraft safely and with
authority first, then you can start making it fly easier, better, straighter,
etc.
It is my strongest possible recommendation that no further test flying be performed
until the cause of the major control difficulties (excess stick force required,
insufficient roll authority in one direction) can be resolved. My recommendation
is to perform what the FAA calls "proof of control" testing as part
of this. Once the cause of the friction and poor cont6rol response is addressed,
it is my further recommendation that initial flight testing be performed at
another location where the physical environment and local restrictions do not
create a serious safety hazard as they did on the flights I was involved with
two weeks ago.
Only after the source of the control issue has been identified, resolved, and the
results have been validated (demonstration of full three-axis control response
and authority) do I believe that "normal" flight operations can resume at
the aircraft's home base of Camarillo UL strip.

If you don't have a set of plans and the construction book you should
contact the factory. I've attached the factory blue print for the rudder
trim tab required. For the roll issue first make sure the flaps are rigged
correctly then you need to check the angle of incidence of each wing and
the horizontal stabilizers.
