RPM Drop From Nuetral to Gear

qkcuda said

I have a 750 DP as well, mine has 4 corner idle. I took off the carb and opened the secondary throttle plates some, so I could close the primaries a little. There is a small set screw in the baseplate. Are you running vacuum advance? If so plug it and see if it makes a difference.

I turned the screw for the secondary throttle position over so I can adjust it from the top. I've got them open as far as I can and still be able to get a response out of the secondary idle mixture screws. If I open them any more, the idle mixture screws won't change anything. Butterflies on both pri and sec are open the same amount.

So far, the vacuum advance has been disconnected and plugged until I sort out the current issues.
