thirdbike Posted May 14, 2011 Share #1 Posted May 14, 2011 (edited) I need you expertise! Could someone please direct me to a schematic that explains the workings of the first generation carbs. An exploded diagram for these particular models with an explanation would be helpful. I was hoping to find a thread with photos of a carb overhaul. I would like to understand a little bit more about what is going on. There are a lot of small holes and orifices that seem to serve similar roles. My current problem is as follows. I removed and cleaned the carbs and have cured my rough acceleration problem. Now, any adjustment to the pilot screw on just one carb makes no difference. Closing the pilot screw all the way on the other carbs causes the engine to stumble while any adjustment on this one carb makes no difference - the engine runs regardless of setting. I guess where I am a bit unsure is the role played by the other small orifices and their routing Thank you.

Venturous Randy Posted May 14, 2011 Share #3 Posted May 14, 2011 Very good information Dingy. We maybe should put this infomation in our technical archives. RandyA Link to comment Share on other sites More sharing options...
thirdbike Posted May 14, 2011 Author Share #4 Posted May 14, 2011 That was fast. Thank you. I don't want to appear ungrateful but to make it even more clearer I would like to see a couple of labelled photos of the actual carb. A complete series of photos showing a tear-down would be the Cadillac solution. The diagram and the articles are a bit superficial. Thank you again.

dingy Posted May 14, 2011 Share #5 Posted May 14, 2011 I have a zip file that has a series of 35 pictures of a set of carbs being tore down. May not have every last detail. 7 meg. PM me an email address. Also watch this seller on ebay, luci0903 , he has an excellent DVD that shows a complete tear down & rebuild of a set of VMax carbs. Usually runs around $15. Didn't see any listed right now. Gary Link to comment Share on other sites More sharing options...
thirdbike Posted May 14, 2011 Author Share #6 Posted May 14, 2011 The pictures are very much appreciated! Too bad it is not earlier in the season or I would put a complete step by step "carb manual" with photos labels and instructions together. This would make a great addition to the archives Thanks once again Dingy Link to comment Share on other sites More sharing options...
GigaWhiskey Posted May 14, 2011 Share #7 Posted May 14, 2011 Make sure you have a washer and an o-ring on each pilot screw. I was missing two. Replaced them and it has made a world of difference. I need to get two more sets cause the other two o-rings look like super flat washers instead of o-rings. Link to comment Share on other sites More sharing options...
dingy Posted May 15, 2011 Share #8 Posted May 15, 2011 Here is something else I did when I stripped the carbs down. This is each O-ring that came out of the carb. I taped them to a piece of card board and noted location. The bottom one is from the fuel bowl side of carb, actually covers the main jet.
