I think there are two possible reasons that I can think of why the power is down, as described above or the increased air flow is resulting in a leaner mixture. I don’t have my wide band sensor setup so I don’t know exactly what is happening. At the moment I am not going to mess about with changing needles but if the low pressure scenario is correct then changing over the piston spring to a lighter spring may be a fix and I’m going to give it a try. If it doesn’t make things better then I will run the standard filter for now.

I haven’t done much with the aesthetics of the car as yet but gave her a a clean and a wax today as I have some Amazons visiting this week.

Looks nice. A polish and wax is good for at least a 5 hp increase. If that is original paint it appears to be in remarkable condition.
Your front grill and headlight surrounds look to be in good condition (same as on my '71 142 E). That soft aluminum usually takes a beating. I spent a lot of time beating dents out, filing and polishing mine to get it looking reasonable. |

From 5 m your paint looks pretty good. Lucky you to have a spare grill.
About 2 yrs after smoothing and polishing my grill and surrounds I got caught in a bad hailstorm. After hammering out the dents a second time, filing and polishing I actually filed right through the soft aluminum in a couple or spots. I filled the small holes with epoxy mixed with aluminum filings and polished down so it doesn't look too bad. I did go looking for a replacement grill; but, de Luxe and Grand Luxe grills in reasonable condition seem to be exceedingly rare on this side of the Atlantic. |

Got the new ATS alloys so now to decide what size tyres; 185 65 or 195 65?

Or 205/60? The 185/65 is smaller in diameter that the 165/80 so not a good idea. You have more than enough width to go wide with these rims. Are they 5, 5.5 or 6?

Yeah the 185/70 would be close but not a common size. 5.5” is the rim width. I might also get the Amazon cars 1” lower springs to go with the wheels. I have 205s on the Amazon and look great but didn’t know about that wide with the ATS rims and the 142 which has a bit more conservative style I think. Any idea what would of been a wide tyre back in the 70s for the 140s. It’s mainly for looks, what suits the rims and the car to be honest.

In the mid '70s 185/70 was the common 'wide tire' fitted on to 140s. That may have been in part due to the fact that 185/70 was a very common tire size in the '70s (good selection) and that the profile height was very close (-2%) to the original 165/80 so the overall final drive ratios didn't change significantly. But, I think the only tires available in the 185/70 size are from Vredstein ($) and Pirelli ($$$). Derek raises a point about tire height. This can be a consideration depending on what final drive ratio you are using. With a 4.1 differential ratio the 185/65 tire will give you a overall final drive ratio that is about the same as the original 165/80 tire with a 4.27 differential. With OD that should be quite acceptable at highway speeds. If you already have a 4.27 differential, then fitting is going to result in higher engine speeds. If you have a lot of hills / low speed driving then you may like that change in overall drive ratio. If you don't have OD / do a lot of high speed driving you may not like the increase in noise. As you note the ATS rims are a 5.5" rim width so the 'common' application guides say that the maximum recommended tire width is 195 mm and the ideal tire width is 175mm - 185 mm. Some tire manufactures list 5.5" rims as acceptable for their 205 mm section width tires; but, when you do that both the tires contact patch and height changes and performance may change.
