Carb sync tool

[RxThunder]

I've seen many of the homemade tools to sync carbs and have no problem making one of my own, my issue is I'm not sure where the hoses actually connect on the carbs, my carbs are freshly cleaned, new exhaust donuts and figured it's time to sync the carbs, I'm sure they're way off. Anyone with pictures or description on where to hook up the hoses and what size hoses to use? Thanks!

That definitly helps. Are there 4 lines to hook up on the 4 cylinders?

Yes, each carb has a nipple on the carb boot, I just synced mine this weekend and it seems crisper

Well, sort of... 2 lines at a time, you just keep the rightmost tube on that cylinder, it is a reference that you sync the rest off of.

If I'm going to hook up all 4 at once, what would I do with the vacume lines for the fuel pump? Could I just t into my same lines for my sync tool?

You need to build a different type of tool for doing all 4 at once, and surprisingly, it isn't as accurate as doing 2 at a time. For the fuel, you just use a T fitting. The fuel pumps don't affect vacuum, they just use the impulses.

Different how? Sorry but just saying different isn't much help.
