carb question

[BassCliff]

Hi,

The idle mixture screw controls ONLY the idle mixture. Yes, turning it out will make the idle mixture richer (add more fuel). But it doesn't anything to any other circuit in the carb.

Read: Plug Chops-Highest RPM Methods and the links on that page.


Thank you for your indulgence,

ok

found it...

while doing my carbs the first time.. the #1 and #4 floats were bent way out... they were allowing the bowls to overfill and not shut off the fuel... while idling as well as while off they would overflow and create running problems...

fixing that part of it now.

am looking at the jets to see if they are right or not as well.

If the bowl vents were blocked wouldn't it cause a reduction in fuel flow and ultimately result in a lean mixture?

Yeah I thought that might be part of it..

so i found out that the main jets are #124 and the air jet on the back of the carb have a #180 on them...

does that sound right.

also talked to a friend of mine and he agreed that if the floats were not in the right position that they could allow the air jet to get clogged with fuel and make it run bad too... going to take care of the float issue tomorrow morning and then get the rest of it back together.. should work just fine after that.
