I have a thunder Tiger Pro .25 engine that is in a coweled P47-thunderbolt. Can anyone give me some pointers on howto extend the needle valve by round 2 inches so that I can adjust it with the cowl on. I have seen many suggestions on the net that I cut a slot in the top of the adjuster and use a screw driver. I would prefer not to use this method as I try to take as few items as necessary with me when I go to the field.
Thanks in advance Gerry
