carb help VM 28 pumpers

[Guest]

Hi working on my 79 1000 , vm 28 pumpers ,, I am not sure if I am doing some thing wrong or what, I have stripped the carb all the way down 2 times dipped them ,took extra time to use air and carb cleaner and blown through every hole , and when I put back on bike ,seams like 1 or 2 don't fire, ,, has any one else been going through this, and is Ultrasonic Cleaner that much better , and is that why I am have so much trouble ,I am not using one .. if so is this one good , ebay #.261860375636 Professional Stainless Steel Ultrasonic Cleaner

thanks Bill B

There's several members that offer carb cleaning services, see the Services forum. That would be cheaper than buying a sonic cleaner

You sure it's the carbs and not the ignition? Does it have points?

Sounds like something other than the carbs. Have you pulled each plug individually to make sure you are getting spark?

alke46 yes I put new plugs , has good spark

Although I do want to eventually buy an ultrasonic cleaner I've always dipped by carbs in proper carb dip and it works just fine. All that being said, I did have a set of 26mm carbs that needed a 3rd dip before I cleared the pilot circuit. After that I started my method of dipping the carb from anywhere between 6 hrs to 24hrs in Berrymans, then putting a guitar wire thru every circuit, then spraying with carb cleaner and air. Never had that issue again. What did you use to dip them with, and how long/how dirty were they? interesting you have 28mm and not the stock 26mm's. I have a set of 28mm and have always wondering what the performance would be like.
