Derrickc14 Posted July 12, 2015 Report Share Posted July 12, 2015 I just started assembling my build and I understand how to sync the carbs at least on stock carbs but I don't know the right height to let the slide and needle come out to. Do I adjust the adjusters on the cap till the slides themselves are not visible at full throttle or what? Is there something I line the bottom of the slide on each side up to in the carb when I full throttle. I've never owned carbs like this.

hoppedupandcutdown Posted July 12, 2015 Report Share Posted July 12, 2015 As far as I know the slides should be completely up at full throttle. But you should get one of these to sync properly. http://www.farmandsandtoys.com/partdetail.asp?partid=59 Quote Link to comment Share on other sites More sharing options...
bansheelapointe Posted July 12, 2015 Report Share Posted July 12, 2015 use the screw top on top of the carb to get them to open at exactly the same time use the one up by the thumb throttle to get them to open all the way Quote Link to comment Share on other sites More sharing options...

uman1030 Posted July 13, 2015 Report Share Posted July 13, 2015 do you have the longer adjusters? I had issues using stock size adjusters on my 35 pwk's, had to get longer ones Quote Link to comment Share on other sites More sharing options...
Derrickc14 Posted July 13, 2015 Author Report Share Posted July 13, 2015 Yea I have them I think. Jeff was suppose to put them in before he sent them but he might have forgotten. I don't know how to tell. I'm going from stock carbs with tors to theses 35mm's so this is kinda new to me on how to set them and etc..

Man-O-Steele Posted July 13, 2015 Report Share Posted July 13, 2015 the stock adjusters are brass and the longer adjusters are not. Quote Link to comment Share on other sites More sharing options...
Derrickc14 Posted July 13, 2015 Author Report Share Posted July 13, 2015 I have them then. Mine are stainless Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted July 14, 2015 Report Share Posted July 14, 2015 Back idle screws out till slides bottom out, set cable play using adjuster on top of carb so slides are pulling equally and opening all the way. Then get a vacuum guage from fast racing set idle to around 4-5 Cfm on both carbs seems easy but I see countless issues with these two steps 1 Quote Link to comment Share on other sites More sharing options...
Derrickc14 Posted July 14, 2015 Author Report Share Posted July 14, 2015 Thanks sleeper. I get them synced. Then back off on the throttle adjuster but it untreatable from the hand throttle housing before carbs go up. I guess that's what the taller adjusters are for. I think I'm thinking to hard about it cause I want it so perfect. Thanks again guys. I'm ordering the vacuum guage and exhaust hangers for the CPI's today from F.A.S.T..

Derrickc14 Posted July 15, 2015 Author Report Share Posted July 15, 2015 Scratch the last thing I said. Ok so when I adjust the slack out of the cable so both carb slides are all the way up and lifting the same, when I use the sync tool to adjust the vacuum at idle and quarter throttle 2 to 3k rpms, won't that make my slides move out of sync if I already had them lifting at the same time or is the adjustments so small to get the vacuum the same on both sides that it won't make a difference.

Man-O-Steele Posted July 15, 2015 Report Share Posted July 15, 2015 i use the idle screw to adjust the vacuum at at idle. if your carbs slides are adjusted correctly then your guage reading should be the same at any rpm. Quote Link to comment Share on other sites More sharing options...
