mikuni carb set up

Hi Warren..if your carb is one of the VM series type then it is very similar to the Amal range of carbs to set up....see

What is different is the cold start operation....

Unlike Amal where a slide is lowered into the venturi in front of the main jet, the Mikuni uses a starting jet at the side of the slide. This has a small rod operated valve which iscontrolled by a built-in side lever. The valve rod itself needs to be down to block the cold start jet which means the choke lever needs to be pulled up....so there is a chance you might be operating this in reverse?....Les

Hi,

just to make it completely clear are you saying Les that for a cold start push the lever down and once running raise it back up? Sorry for being dim just need to clarify. Thanks Paul.

If it's a 1973 850 then a 932 Mk 1 Amal will solve your problem and restore your street cred at the same time. Problem solved!

Hi Paul...Yep, that's it... push down the end of the lever for a cold start and lift the lever fully to turn off the cold start jet...for normal running....Les

Thanks Les,

had a few rough running problems with my mark 3 and when I first read your post I thought I'd been running on choke! Thanks Paul.
