Welcome to our Site for MG, Triumph and Austin-Healey Car Information.
Triumph TR6 - Strombergs or SU's?
I'm contemplating going to HS6's based on various bits of information I've heard, but I'd like to hear first hand from members of the forum who have done this about their experiences? What differences did you notice? More performance? Better driveability? Anything else? Oh, and what was YOUR motivation to change? Cheers, Dave |

Dave I was in Calgary last week (visiting from Nova Scotia), and I had the opportunity to vist Sports Car Parts (lots of Brit/bits cars), the staff there were very knowledgeable, so try and call Dale. Temperture here on Saturday will be +11C so its a day on the rebuild....install steering rack, front discs, and sway bar. Les |

Dave Not trying to be smart here but you might get a faster answer if you look at the Archives (link above). The BBS is kinda quiet and possibly the chaps who have done this are "away" shall I say. I know the same question has been asked. choose a year then just start scrolling down the threads.Besides the ARCHIVES I just did a quick google of "HS6 Carburetors" and saw 2 links to changing to HS6 carbs..one for am MG the other for a 73 TR6. Have fun. Rickc |

Hi Dave, I found my ZS carbs even after 2 rebuilds were never great,they would somehow change / based on weather or engine temp..especially after a long drive. The temp compensators and bypass valves are a pain as well, I got them set up pretty good and all is documented if you need any info. I installed SU's 2 years ago and they are amazing..no complicated parts and less time tinkering with them..run great all the time. Charlie |

I'm familiar with the Zenith Stromberg (ZS) but not with the SU. So I'll tell you my experiences. Charlie is correct about The temp compensators and bypass valves can be a pain if not adjusted correctly. The key with multiple ZS's is to have the temp compensators adjusted so that they open and close at the same time. Once adjusted, you really don't touch them again. If you don't know what the temp compensator is, look at my picture. They are located behind the air cleaners on the right side of each of them. They have the long discolored off white plastic cover on them. I look at adjusting carb air/fuel mixture as the car is talking to you. If it's a hot or cold day, the car will tell you how to adjust, it only take a few minutes. So it's not a pain if you know what the signs are. With the ZS's, the car will speak to you by reacting by the following 1)If the idle stumbles and it smells like gas, it's to rich. Verify it by looking at the spark plugs. They're probably dark grey to black. 2)If at idle it miss fires consistently, (kind of like a machine gun) it's to lean. Verify it by looking at the spark plugs. They're probably light grey to white. Being that I have the triple carb set-up, I adjust mine so that the carbs run just a little lean. I Adjust them when the engine is warmed up. That way, my temp compensators are open. I verify the mixture by looking at the spark plugs and making sure they are grey to light medium grey. I've got mine so dialed that I haven't adjusted them for about a year. Hope this helps you on your decision making process. ![]() |
