    So I'm working on a full carb rebuild on my 82 seca 750, I have replaced everything else but these, I can't find them inside the carb anywhere or anything that looks similar. Can someone point me in the right direction? Thanks!

    My WAG is the anti-tamper plugs for the mixture screws.

    Another question, I'm needing to disconnect the tci to do a compression test and I cannot for the life of me get these connectors to let go! Any tips or tricks? 20190911_231713.jpg

    Pull harder. Then put some silicone grease in the plug terminals before you re-connect it.

    I finally got them! I don't think it had ever been pulled off, I was worried about the connector breaking, now to rebuild my petcock and get my wiring cleaned up and hopefully I'll be good to go

    Yes take your time with those carbs and do them right the first time. Bench test them for fuel level, leaking gas and make sure the diaphragms are working.....it will really save you time in the long run.

    I've actually replaced everything inside the carbs except for the float bowl drain screws, and that's simply because the heads are so stripped I cant get them out except for one. I've tried every screwdriver in my garage, including a manual impact driver with zero luck. I really don't want to drill them out and mess something up so they may just have to stay 20190912_180431.jpg 20190912_180438.jpg 20190912_180428.jpg 20190912_180431.jpg 20190912_180438.jpg

    torch the screw with a mini torch and spray pb blaster around the screw head. You will have to get them out and get some functional to set the wet levels. I just used my TIG and stuck a booger on the screw head for the vise-grips.

    I actually hadn't thought of just attaching a booger to grab with vice grips! Thanks I'll be pulling them tomorrow!

    Yes, you will want to remove the bowls before you work on them.

    The bowls came off no problem, the drain screws on the other hand are the devil

    Yeah, I had a few stripped on the brackets as well as drain screws. Soft metal screws, even with JIS drivers they can be a pain if seized.

    I took my drain screws out with one of those screw removal tools, the reverse drill bit. Then bought replacements from xj4ever
