Shadow Posted January 16, 2011 Share Posted January 16, 2011 I decided to open up my used carbs (40dcoe27) and give them a rebuild. During inspection I realized the top cover was damaged. Particularly the two posts that the float bowl attaches to. One post in 2 of the 3 carbs have broken and the previous owner wired the pin to the post. Is there a way I can fix this? If not where can I purchase a new top cover? Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted January 16, 2011 Share Posted January 16, 2011 (edited) You can probably buy a top cover... Me, in my cheapness and impatience would probably rig up a repair. My repair would look better than that though! That repair probably works fine but I would cut off half the post, clean, fab up a replacement chunk and pin it with a dowel or screw. I would also investigate fuel proof epoxies. Edited January 16, 2011 by cygnusx1 Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted January 16, 2011 Share Posted January 16, 2011 (edited) I would fab a new post and attach it to the inside of the broken one. I would drill and tap the existing one in 2 places and narrow up the float to fit. Replacing the existing unit is the best option, but It could be fixed. I have bought parts from http://redlineweber.com/html/application_guide/Table_of_Contents.htm with good results.

jasper Posted January 16, 2011 Share Posted January 16, 2011 I would repair with a JB WELD/ LIQUID STEEL/PC7 type of product. Strong, and can be drilled and filed. Use a plastic dowel in place of the pivot pin during moulding. This can easily be removed after product cures. Quote Link to comment Share on other sites More sharing options...
Shadow Posted January 16, 2011 Author Share Posted January 16, 2011 Thanks guys. I think I will try to fab new posts. Im just too cheap to buy a new cover right now. Thats why im keeping the L series in there. Look for a build thread soon Quote Link to comment Share on other sites More sharing options...
GOTAZ Posted January 16, 2011 Share Posted January 16, 2011 I 2nd Jasper's call on JB Weld. Get the hardener-to-resin ratio as precise as possible, mix thoroughly and be certain the parts to be glued are clean. Chlorinated brake cleaner is good for flushing any remaining grease, oil, etc off the parts. Beware that chlorinated solvents are carcinogenic; use at your own risk. I use it outdoors, wear nitrile gloves and don't breath the fumes. Good luck. Quote Link to comment Share on other sites More sharing options...
