I seem to remember a john deere effect
Sorry Scott ............ I thought I responded

Yuppers, mine was popping away like a Jiffy Pop on the oven at first, but only when unloaded.

Over the course of the next tank or two, it stopped popping

I stopped wondering when it stopped popping .............. some things are better left alone ;)

I think it was too much fuel, I seem to be getting more time on a tank too.
IIRC, twas Scott that first said excess fuel

It is an old thread I know but some recent port work on my 461 got me thinking. There have been several models released : the strato'd 261, 400, 462, the injected 500 and the oldish school 881 and none appear to have these "flanges" or diverters/stuffers.
So has anyone experimented and removed them on either the 461 or the 661 with noticeable affect, good or bad?

The information I heard, which I believe came through Randy, was that the saddles were installed because the pistons were getting too hot, and the diverted charge cooled them down a bit.

I imagine that removing the limiters on the carb reduces (or eliminates) this problem, but I've never removed the saddle and I'm not sure if removing it would benefit anything. In fact, I would imagine it would serve a little like a crank stuffer.

Any reason you want to remove the saddle?

Old version 462 has it. Interestingly they delete that in the new version?

Wasn’t there a few failures. Ie pistons with fractures.. although I’m not sure why the saddle would interfere…

I’m sure someone will chime in as why etc.

Other than the cooling effect that’s talked about I’ve always looked it as it’s there to help push the charge to the lower transfers in the front.
