Can someone verify the thread size on a Simmons idle jet? The thread size on a Zenith idle jet is M5x.75 metric.

Other than the thread size possibly different. Is there any other difference in the idle jet compared to a Zenith?

Thanks in advance

Was just looking at a Simmons thread by Purdy Swoft dated 12-21-2012. He listed photos but they are no longer with the thread.

Here is the idle jet, it is similar but about 1/8 inch longer than the Zenith idle jet and the threads are different.
 
10/32 nc? not same threads as zenith! try a tap to make sure or a 10-32NC screw to verify. length is the same: cap jet same threads as idle jet in simmons
 
Gary, idle jet and comp jet are 10-32 as you stated. Maybe Renners has the idle jets?
