Proform 850 dialing it in closer

I will read that link and Thank You.

It only comes out of the garage to go on a trailer to race at the track.

I sneak it out into the back 40 for a few small tests but it hasn't been licence sence 2003.

I'm running Sunoco leaded.....110 or 112 Race Gas, can't remember right now. have to go to my buddy's shop and look.


Then you can probably trim the fuel ring down some, the MPH will tell you how far to go.

You may want to start working with the MAB. That gets tricky.

Im also inclined to think that when a main jet change is too much, you can either open the bottom emulsion hole .004 or if you have a 4 or 5 emulsion metering block you can add slower hole and maybe start with a .024ish hole.
