Hello, I am wondering whether the gear wear as shown in the attached pictures is acceptable. Back story: These gears came out of a car that had a lot of growl noise when driving in first and second gear. The growl had some rattly-noise to it, with about about a 4 to 6Hz modulation to that...

Parts arrived from Renner's corner exactly as ordered. My reports of their demise are greatly exaggerated.

@MAG: Thanks for that tip. I had been wondering what the spring-looking-like thing was in the pictures on Vince F.'s website... had thought it was a thread, turns out it's a, uh... spring, duh..... I'm guessing my carb-in-question is missing that spring part, as the GAV turns with much less...

I have a Model B carburettor for which the GAV does not seem to work correctly. The carb. runs rich independent of whether the GAV is fully closed, fully open, or anywhere in between (it is running at 10 ~ 11 as measured by an A/F meter independent of the GAV position). Off the car, I notice...

Hello, Is there any known/established upper limit on spark plug resistance, particularly for the inner conductor? I pulled one plug from a cylinder from which I was not getting any significant power (shorting the spark wire to ground did not result in any significant decrease in engine idle...

Took my '31 Roadster out for the first time in a few months, not noticing that all coolant had leaked out. While driving, I attributed the burning smell I kept getting to some oil I had spilled on the exhaust manifold during a recent oil change. Finally realised the engine was overheating when...

Hi folks, Yes, that actually makes sense (much more than a 10-34 tap does), given that Zenith used metric units for dimensions of other parts. Don't know why I didn't think of that. Cheers, Andrew

Hi folks, My reading and measurements indicate that the threads on Model B carb. jets (e.g. main, cap, other) are 10-34, yes, ten dash thirty four, not the standard 10-32. No amount of Googling has yet enabled me to find a source for such a thread (save for one, which is actually a typo)...

I purchased (what I thought was) a Model B carburettor, for the purposes of acquiring a core to be re-built. I didn't look close enough, for though it has nearly the form of a Model B carb., it has some clear differences, as shown in the attached pictures. As shown in the first picture, I see...

FWIW, I have had two 'modern' (neoprene?) rear main seals fail on me after <1000 miles. I have since reverted to the traditional seal set-up, providing no more than minor oil leakage for ~6000 mi. over the last eight months.

I am very sorry to hear that kind sir. May the honour of your son and your family live on. -Andrew

Hi folks, I recently had to repair even the A&L US-made brake light switch with the brass bushings, even after only ~6 months of daily use. I was not very happy about that, for, given that one has to severely deform and re-deform the sheet metal tabs in order to open and re-close it, I have...

... & How.

You may be reacting to a warning, as a result of California Proposition 65, which will inform you that Marvel Mystery Oil contains chemicals which may be, in some way harmful. The correct interpretation of this warning is that you should not pour Marvel Mystery Oil on your morning scrambled...

I drove my '31 Roadster today from Los Gatos (southern SF Bay Area) to Lake Berryessa and back for some jet-skiing with my son. That's 225 miles of driving round trip, in particularly hot weather - about 95ºF for most of the drive. With the top down, hat on, and a bottle of water at the ready...
