#167318 daglassguy (User) Fresh Boarder Posts: 77 Float valve & needle MPG nightmare 8 Months, 4 Weeks ago   For 5 years was getting consistant 52 mpg with barons big air kit and setup. Suddenly milage droped to 23 mpg. Took carb off and checked everything visually. Decided to port manafold and go to 167 main. Still getting rotten milage. Then checked float level and found it way high. After numerous assembly and dissasembly found that it would only adjust to wide open or off. Looked closely at needle and could not see anything wrong with it. Installed another used needle and float became adjustable again. Milage came back up again (not sure how much yet). Have a new needle and seat ordered and will install. I had no idea that float level affected mpg that much. Hope this helps someone else who is having similar trouble.   Logged     The administrator has disabled public write access. #167343 Questcap (User) Platinum Boarder Posts: 1244 Re:Float valve & needle MPG nightmare 8 Months, 4 Weeks ago   Actually, it is likely to effect mileage more than any other variable! Especially when, as you put it, it was way high!   Logged     Sig pic deleted - larger than 450 pixels and 50 kb   The administrator has disabled public write access. #167392 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 14517 Re:Float valve & needle MPG nightmare 8 Months, 4 Weeks ago   Yes ... float level very important and often overlooked. The needle and the seat also wear out over time and need to be replaced.

When I visually inspected the needle everything looked good. Checked the little spring gizmo on end and it was moving up and down freely. I compared the one I put in and the old one and could see a very little angle change on the beveled end. But just looking at it, their didnt seem to be any wear.   Logged     The administrator has disabled public write access.
