Good morning, hope everyone had an awesome and safe weekend so far. ok question for today. If i used my ultra sonic cleaner to clean the jets and just bought gaskets for the carbs, should that do the job or should? Or should i just buy rebuild kits then save old jets. Not sure what to do... seems like i need just a good cleaning.. Any suggestions.. Thanks guys..

Sonic cleaning is the absolute best way to go when cleaning the carbs. However, it will not clean the inside of the low jet, main jets and air bleed jets out. Those need to be done by hand using drill bits. This is a link to the process I use to remove the low jet and the drill sizes for each jet. It's ultimately the only way I have found to clean everything out and get the low to mid range stumbles and flat spot out of the carbs performance. If you want a more up to date detailed description of the process, look in my signature here. The book has better descriptions and pictures of step by step through out the procedure.

I am a proponent of cleaning rather than replacing. You do have to be sure that you have all the deposits removed from the jets tho. A ultrasonic is a great tool, but may not break down all deposits. That is the reason for the judicious use of a properly sized drill bit to insure the hole is the correct size. Larry lists the sizes in his carb book, but I think that .018" is the size for the idle jet.



You don't want to remove any brass or reform the flow of the jet, but by being just a little careful and using the bit in your fingers only, you should be able to do a proper job. Go to the quick reference in the General Discussion, I think the info is also there.

The bowl gasket is rubber and usually reusable. Check/replace the o-rings between the intake manifolds (insulators) and the heads. I have cleaned/serviced quite a few carb sets over the years and NEVER bought a rebuild kit, or any new carb parts for that matter. If they are damaged though, they need to be replaced.
