VM20 Carb top

I’ve always had problems unscrewing the carb top of these smaller carbs. But today, I came to the realization that what makes the top difficult to screw on & off is the choke lever!

If you simply depress the choke lever down, as in activating the choke, all of a sudden the cap unscrews totally unencumbered!

I never read anyone talking about this so I thought I’d bring this up. I had to remove the cap because the throttle wasn’t returning quickly & easily. So once I got the slide out, I put in a heavier gauge slide spring with more turns in it. The spring which was in the carb was the lightest weight spring I’d ever seen in ANY Mikuni carb.

I had about 12-14 different carb springs in my carb box. So changing to a heavier gauge spring gave me a much better throttle return. Sure glad I got this box with my first Hodie! It’s made life a lot easier, time after time, after time, after...... :ugeek: Victor

Kinda like throwing all your small wrenches away and just buying a 12 inch crescent.

There are two size carb caps for early and later carb. But to the threads kinda also go always. So here Greg has had these made for a fix

The trick I guess is how to ID early vs late. I will have to ask Greg

We were joking at HD about how many carbs there are without the cap, slide, spring and needle because someone took them out and left them hanging on the end of the throttle cable. So out there also are slide assemblies that no-one knows what they go to hanging on cables......
