Greg Marsh Enterprises is a full dealer for Amal, Tri-Spark, Wassel, Central Wheel Components, and a reseller for Andover Norton, JRC Engineering, and Colorado Norton Works.

Members of this forum always pay less than the prices published on my web site:


Amal premier carb sets for Norton Commandos are $455.00 delivered to the US and I don't sell generic sets - only the correct set for your bike.

Tri-Spark Ignitions for singles and twins are $225.00 delivered to the US. These are the new version that work both CW and CCW. I also have the Triumph Twin CW Only for $215.00 delivered to the US and the Triumph/BSA Triple for $250.00 delivered to the US.

Tri-Spark MOSFET Regulators are $105.00 delivered to the US.

A Tri-Spark Twin Ignition and MOSFET ordered together are $315.00 delivered to the US.

I bought out the Old Britts AN stock below cost and am selling to forum members very inexpensively. Besides the Old Britts stock, I have over 2000 Andover Norton parts.

I sell Lucas, Hepolite, and Girling for less than anyone I am aware of. These are all from Wassel and are quality products. I sell/can get other Wassel products, and I try to weed out the bad ones. For instance, anything Lucas-like is junk, the petcocks they sell are excellent. They sell several different twistgrips – some junk, some excellent.
You can fill a cart and request a quote. Better still is write or call me and we can figure out what you need together. 703-200-4025 or

The last number in each is the pilot jet. Amal says that 750s should use #17 and 850s should use #19. Many prefer #19 for 750 as well. Pilot jets cost a ridiculous amount of money, but I have some Amal provided to shut me up about the issue so I can usually provide #19 when requested with a PACK set.

If you don't know about "PACK" numbers, they are sets of Premier carbs. The non-Premier sets are "ACK" numbers (no longer available). Each PACK set includes the carbs with the traditional sub-number on the side. For instance, if you have a Combat it came from the factory with the carbs R932/19 & L932/20 and that's what PACK 140 contains. To figure out which PACK you need, see the bottom of this page: the list above can be used, but there are quite a few notes on the CommandoID page. For instance, the application data above is what Amal says but PACK 139 is confusing - it's certainly for 72 non-Combat and if your 73 had 30mm carbs it's for that too, but most 73 750s need PACK 112. If you have trouble figuring it out, I'm happy to help.
