carb adjusting question

[hotrodbelair]

i tried searching but coulding find anything. i rejetted my ex with a 145 pilot and a 170 main. and i ran through all gears did a plug check brown plug, thats good right? but when i hold it right around half throttle it bogs a little bit till i crack the throttle and it clears right out. what do i adjust on for this? thanks

145 pilot? .........check your air/fuel mixture screw on the underside of your carb.

The fuel screw on the side of the carb controls 1/4 - 3/4 throttle, sounds like its running lean maybe back it out a 1/4 a turn or so and see if that helps out any.

Needle position would be the problem.

Bingo, we have a winner :D


Try raising the needle (lower the clip) one position and try again. You might possibly have to go 2 positions, but one position is likely to clear things up.
