I have a chance to trade my 165 for a 250 . I know the 250 is worth more but do you guys think its worth the effort to change over? iirc the 250 is not adjustable , and dont want issues down the road .

Make sure the 250 doesn't have a small step off the back of the motor housing before the rotor cap. They had a little different rotor design that might have a tough time keeping up with the fuel delivery.

do you have any pics of what your talking about?
I guess im lost on the fuel delivery part .......... you mean a 250 pump wont be able to keep up as good as a 165??

No i just mean that the older style 250 pump will not keep up with a newer 165.

If you look at where the back cover is (grey piece), the older style will have a small step between that and the motor tower.
