<div dir="auto">Must jump in here. Just to muddy the waters a bit, although not relevant to Big Healeys, the SU H1 carburettor on Morris Minor and Sprite MkI (Frogeye) do not have piston damper springs. Springs with a red paint splash started on the MkIIs and Midget MkI.<div dir="auto">Carry on, I'm learning a lot!</div><div dir="auto"><br></div><div dir="auto">Dave W</div><div dir="auto">'59 :()</div><div dir="auto">'59 MGA 1500</div><div dir="auto">"Pay It Forward"</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Fri, Dec 27, 2024, 3:16 PM rct2bnc--- via Healeys <<a href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font-family:Tahoma,Arial,Helvetica,sans-serif;font-size:16px"><div></div>
<div dir="ltr">I have also run into this problem, but not with any of my Austin Healeys. I have a tri-carb set up on an 1959 AC Ace. When I opened the carbs to check and add oil, there was only a brass cap with no damper mechanism. Also after removing the chamber I found no spring and a solid piston rod with no place to put the oil. Luckily, I have a 2003 SU reference manual for most British cars using SU carbs. Each make is broken down by year, type of carb, needles etc. but includes all miscellaneous parts like damper, jet, float, service kit #s, and more. It listed at 1.9 litre Weller six-cylinder engine from 1933- 1952 - all the triple carb set ups. Under damper it states: CAP; for piston spring there is no entry. Without going through the whole manual, you can see that many, many pre-1952 cars, such as: Alvis, Aston-Martin, Armstorng-Siddeley, Bentley-Rolls Royce, Frazer-Nash have CAP and no springs. However, under the listings for all Austin Healey cars (including Sprites) from 1952 - 1974, all carbs on those cars show dampers and springs, without exception. This includes 1954-56 100 M Le Mans and 1955-56 100 S 4 cyl cars. </div><div dir="ltr"><br></div><div dir="ltr">As for the CAP unit, the manual shows 7 variants, from plain brass hexagon, some knurled brass round and some with stamps for OIL RESERVOIR or THIN OIL. They also list 5 different dampers with both brass and plastic caps. </div><div dir="ltr"><br></div><div dir="ltr">I can scan the Austin Healey section and attach for the group, if there is interest.</div><div dir="ltr"><br></div><div dir="ltr">Ben Cohen</div><div dir="ltr"><br></div><div dir="ltr">BN1</div><div dir="ltr">BN7</div><div dir="ltr">BJ8</div><div dir="ltr"><br></div><div dir="ltr"><br></div><div><br></div>

<div><div dir="ltr">ran into something have not seen before. cleaning the carbs on an MGTC and discovered there is no damper. there is a plastic cap and a 3/16 hole approx 1/4 inch deep in top of piston rod. Moss shows a damper and so does the workshop manual. any ideas what i have here?<br></div><div dir="ltr">_______________________________________________<br></div><div dir="ltr">Support Team.Net <a href="http://www.team.net/donate.html" rel="nofollow noreferrer" target="_blank">http://www.team.net/donate.html</a><br></div><div dir="ltr">Suggested annual donation $12.75<br></div><div dir="ltr"><br></div><div dir="ltr">Archive: <a href="http://www.team.net/pipermail/healeys" rel="nofollow noreferrer" target="_blank">http://www.team.net/pipermail/healeys</a> <a href="http://autox.team.net/archive/healeys" rel="nofollow noreferrer" target="_blank">http://autox.team.net/archive/healeys</a><br></div><div dir="ltr"><br></div><div dir="ltr"><a href="mailto:Healeys@autox.team.net" rel="nofollow noreferrer" target="_blank">Healeys@autox.team.net</a><br></div><div dir="ltr"><a href="http://autox.team.net/mailman/listinfo/healeys" rel="nofollow noreferrer" target="_blank">http://autox.team.net/mailman/listinfo/healeys</a><br></div><div dir="ltr"><br></div><div dir="ltr">Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/healeys/rct2bnc@aol.com" rel="nofollow noreferrer" target="_blank">http://autox.team.net/mailman/options/healeys/rct2bnc@aol.com</a><br></div><div dir="ltr"><br></div></div>
