I'm now trying to fine tune my 1.7 Djet and needing to clarify a thing or 2. I have read the stuff from pbanders (Thanks for putting this info out there) time and time again, and also the stuff from Kjell Nelin (Thanks to you also). I can not drive my 914 yet so I know that I cant fully tune it yet. But, in all of the reading, do I really need to worry too much about the AAR and the decel valve ?? I sprayed my AAR down with penetrating oil before I mounted it, and it is frozen up again already. If the AAR and decel valve arent really needed, I would rather just eliminate them. I dont have to worry about passing smog because we dont test here,and I can live with some popping and cold warm up issues. I just need some input before I ditch them. Thanks in advance !!

Northeast here, so very cold.
No AAR, no decel, no cold start injector.

Runs perfectly fine without them.
Plug the plenum.

You don't need them in Tx.
2 less things to go wrong.
