I'm New Here
I recently purchased an RV-8. We decided to change the throttle/mixture/prop assembly because it was not doing well after a lot of years of use. We noticed that the builder made some interesting (not direct) routing from the cockpit to the servo fuel injector. We installed the new assembly and realigned the linkages. Everything works great EXCEPT until we install the lower cowl. The mixture linkage / mixture arm bolt rubs on the lower cowl. The issue is the space between the lower cowl and the bolt connecting the mixture linkage to the mixture arm which attached to the servo fuel injector. If the width of the bold and castle nut were 1/8" shorter my problem would be solved.
The only options that I see is to purchase an slightly smaller mixture arm ( the current arm is cast metal which will not bend but will break if bent), figure out how to use fewer washers on the bolt or make a opening in the lower cowl to accommodate the movement of the mixture linkage. The opening would then be covered with a fiberglass bubble and painted.
Any suggestions would be greatly appreciated.
Thanks
Alan
