Title: Vm28 final jet. Configuration
Post by: Jeff XL79 on February 23, 2025, 01:02:53 PM

Would anyone care to share what your Mikuni vm28 jet  combination was? This is on a Casler 45 with dual ignition. Thank you.

I've verified the main (200) and the idle (60) jets in my new vm28 carbs from Summit.
Also, I had ordered a 42 piece set of aftermarket jets from Amazon thinking that they would work. Well, they aren't even close.  Under magnification you could see the holes weren't even close to the mikuni jets. If they have a number system that corresponds to anything it isn't supplied. 
Obviously I need to get oem jets to keep from getting completely out in the weeds.

Going to start with 150 and 160 main jets and 40 and 50 for the idle circuit.  I don't have a egt or a cht gauge so I'm going to go mainly by plug color and rpm with a smooth transition. Still open to anyone sharing what combination of jets they're using also.

I did searches using idle, jets, vm28, mikuni and a couple more variations and didn't see that post. Thanks for the info.
