If the doors are original the holes are already there

I was told many years ago by Darryl Uprichard of Racetorations that they set all their floats to 5mm. ( This must only apply to the brass type. ) I did this with my triples and it made a critical difference. Later I got a clear gauge to measure the fuel depth from the top of the well ( where the main tube screws in - remove to check ). I found that 5mm with 3-ring vintage Italian 40DCOE-18s this gives 27mm depth. Oddly, older 40DCOE-18s with brass shafts on another engine gives 27mm with a setting of 8mm. Such depth is the key to when the main systems enters the game, the higher the

This is a work of art in its own right and it's obvious with circa (20) sections welded together it's not commercially viable. Richard Good's " inability " to build it in stainless must mean " for an acceptable price ". From what I've seen on this thread the GOODPARTS design in coated mild steel is still the competitively priced best performance option. I would be quite surprised if he doesn't know whether the RHD cars will accommodate it, less surprised if they cannot. I have no financial interest and provide this link just FYI: https://www.goodparts.com/product-ca

6-3-1 pairing 1-6,2-5 and 3-4 gives them equal firing order spacing. Richard Good's version has equal length primaries and secondaries which he tested against Phoenix's version where they are apparently unequal and found a big difference in his favor. The downside is Richard " cannot build it in stainless " ostensibly due to the metal's relative reluctance to bend into the tight radius required for 1 & 6 cylinders where mild steel can. He has his " ceramic " coated in (3) different temperature ranges. I have experience with this on my trick engine with very high lift cam and triple DC

Hi Tom,
Regarding your TR250 crankcase ventilation system, particularly the photo of the air cleaner (2008 post) showing a hose from the air cleaner to the emissions valve, you state the hole is restricted.. Would you recall the size of the hole? I am installing the same set up on my triple S.U. carbureted TR6 engine. I currently have the hose from the emissions valve attached to the port on the center carb (other two carb ports are capped) but not sure if as good as to the air cleaner. I am experiencing a bit of surging on mild acceleration, but not sure of the cause. Perhaps attaching the hose to a barb on the airbag (Richard Good title SU air box) may be better. Thank you!

Hi 75,
Here's a photo showing the orifice; 1/8" IIRC. I think you reached me on the TRIUMPH EXPERIENCE site, right? I'm not very active on these forums lately as TRs are celebratory for me, and that mood is in a state of suspension for now.
Regards,
Tom
