I apologize for some of the dumb questions I've asked on this site but I got one more just in case someone might know a fix.

I wanted to ask you if anyone knew anything about the TEV? For mine with just the spring it dips way under idle almost stalling or with a few washers to help put tension on the spring fixes the dipping under idle but brings some very loud decelerating backfiring.. It's a 2012, Dyna Muffler, Lancer Jet Kit, stock 52.5 pilot and 150 main, 3 washers in place of white spacer, PowerStar Spark plug, Cone Air Filter, a/f screw between 1 1/2 - 2 turns out...   I'm at about 900ft elevation.. I just can't seem to get the bike to stop dipping under idle with just the TEV spring in there and when I add washer or washers it does not dip below idle anymore but backfires real loud when decelerating... I don't know what to do to keep the bike from backfiring during decelerating and keep from dipping under idle at the same time.

Thank you to anyone that can help

Thanks

I answered your Personal Mesage about this......you can see the long answer by going to your messages.

I agre with Apache Snow.....the TEV is not often the cause of running issues.....provided the passages are clean and it works as it was designed.

When the engine drops rpms below the idle - it is an indication that the mixture has gone too rich or too lean.  It could be that a mixture or jet adjustment could change the problem.......or maybe it is a sticky slide that is not seating completely until the engine stops.  I imagine the stalling issue only occurs when you are sitting still.....the engine is not stalling while you are moving?

Try turning the screw out 1/4 turn at a time and see what happens.  If the issue becomes worse then maybe the carb is set too rich.  If there is no difference and you get 3 turns out....then maybe up to a #55 pilot....however the need for a #55 is questionable as that is a very rich jet for the Savage.

If your fix creates a new problem, then what was fixed was not the problem.
return it to stock and try another.

1st be certain, you have a clean carb and you have assembled it correctly. Next make all adjustments as best you can.

You might even have to redo some and start all over.

Idle speed seems to affect all others, so try a high idle speed (1200 rpm) and if that didn't work try a low (1000).

Mine used to shut off if I was running at high speed & slapped the gas shut.
Raised the idle & that went away
