@@BWRBMW it is always more satisfying to build your own especially if it is basket case. Regarding price, maybe we could do a raffle when I decide to downsize 😄
Great video , thank you for making it , do you know the basic setting for the idle screw is it also one and a half turns out ? , also is that a vent hole port on the outside of the carb slide body , it has a slope side with a hole in it ? All the best , Don.
Idle screw initial setting is one turn in after it starts lifting the slide. You will hear the screw changes the sound as you are turning it in. When it changes the sound, it means it started lifting the slide. Another way of doing this if you are not able to hear this sound change, is to lift throttle cable just tiny bit up just to remove any cable free play. Turn the screw in until cable starts lifting. That’s your touch point. Then one full turn in and that’s the initial setting for idle screw. That hole is a vent and very important is to make sure it is clean. During rebuild and not shown in this video, I always squirt carb cleaner and do compressed air pass on each opening in carb after ultrasonic cleaning just to make sure there isn’t any plugged hole. Hope this helps and thanks for watching!
I am the proud owner of 1975 R90S serial No. 4980095. I understand that the Delorto community is small and I appreciate your taking the time to enlighten us as to the internal workings of the Carbs. I would like to suggest a video on the vacuum port modification to these Carbs. Dale
Great video just got a 1974 and 1976 r90s, 74 need the carb done,
Great walk through. Some day I will have something with DellOrtos and will be watching again 😂
You wanna buy it 😄
@@airheadbarn ha I can’t afford a beautifully restored 90S. I could maybe afford a box of parts then go to your videos to put it together 😅

Great video! I own a 1975 R90S and I would love to see a video on how you go about balancing and adjusting these carbs.
@ thanks for the advice. I’ll try to get that done
