I have been eyeballing the mixture screws since I bought the boat. i noticed the middle carb has the mixture screw turned in twice as far as the upper and lower. it'd seem to me these should the same but since the upper carb and lower carb feed two cyclinders it'd be different..since the middle carb feeds only the number cyclinder...it seems to be running good from the hole shot the plane but the fuel comsumption is about a gal an hour which seems high....which leads me to ask this....

All three out the same. As mentioned add infinitem, 1 1/8 turn out from lightly seated. Fine tune from there. The search function is a miracle worker

Center carb has a smaller main jet, than the top and bottom carbs.

They shoud be about the same.In the other post I gave instructions on how to set them.
The top and bottom feed two the center feeds one.They are jetted differently to compensate for the amount of feed.

Food the search feature is a pain in the *** on this site. Seems like everything pops up other than what you're looking for then you have to sift through it.

+2.

I've been struggling using the Search function with this site as well. Not sure if there's something the Moderators can do to improve this function. I'm sure it would encourage more people to use it.
