QUOTE(toon1 @ Nov 29 2015, 09:26 PM) my AAR was bad. There was likely something else that was going on... In a properly set up injection system (L-jet or D-jet!) the AAR should not affect the mixture. At all. The air going through the AAR is metered air; L-jet takes the air from downstream of the air flow meter, while the D-jet MPS sees the higher pressure of air getting in. In your case, there may have been something else going on. --DD |

QUOTE(pete000 @ Nov 30 2015, 09:15 AM) If you by pass the AAR with a straight hose you will find the idle will race up to over 2K. Then you can pinch the hose down to reduced the air flow and you will notice the rpms dropping. I found the hose has to be pinched real tight to get it to idle near 1K. I did this just as a test to see how the principal of the AAR worked. If you plug the hose ends or cut off all the air flow the engine will have a tough time idling when cold. It wants more air when cold. It can be frustrating I know, I have been trying to get my L-Jet to idle properly when cold. Even with the properly working AAR mine wont idle for a few minuets on its own. The AAR can be slightly adjusted to allow a bit more air flow with the end point stop. I have mine set to allow the most air flow. I am currently testing for air leaks and having the TB rebuilt. The TB's can become warn and cause leaks. The most important part of the L-Jet is to get rid of any Vacuum leaks. There are many places that can cause leaks. Thank you Pete |

The Army has warped my brain and I keep thinking AAR means After Action Review...
