On a 1929 model A speedster with the original zenith carburetor and Offenhauser pressure regulator-what setting should the regulator be set at?

I don't have first hand experience with this combination, but I think 2 to 4 psi would be the proper range. Factory Model As did not have a fuel pump, just gravity feed, right?

Given that thte carburetor only saw the pressure created by about 24 inches of gasoline, which is less that one pound of pressure, I would set it at 1 to 1.5 pounds.

I'm running power curve headers with the 4" slip ons and a K&N high flow intake. With just putting the slip ons on an everything else stock, you should not have to tune, but if u have headers or different intake then stock you will have to tune, and no the bike dose not really run cooler. The only thing your gonna get from the slip ons is louder exhaust. Hope that helps.

I am a DIYer and not a small engine expert. My engine is a HMSK 100 and the only marking I could find on the old carb was 1433A which is probably a casting number. The picture correctly portrays the carb I and presently using. By the way, I used it for about an hour yesterday and it started and ran like new. Bernie Z

The settings above 5 are 6, 8, 10, 15, 25. Nice little regulator. Works well.

I sold my unit and bought another brand, so I have nothing to look at to help you. Your best bet might to to find one on display at a store and look at it or check youtube. There are carb rebuild videos on youtube.

TO SET THE TACHOMETER (SPARK PLUG FIRING REVOLUTION):Press and hold the S1 button for 4 seconds. The LCD will display 01 (spark plug fires twice per revolution),02 (once per revolution), 03 (every other revolution), 04 (hour only, will not display RPM).Once you find your desired spark plug firing pattern, release the S1 button.The LCD will blink for 8 to 10 seconds and return to total hour meter mode.The default for the standard model is 02 (once per revolution).

Look at the photos carefully. Make sure both the throttle and the choke levers in the photo matches your carb exactly. You will not need any other parts. This carb doesnt have an adjustable mixture, but it is set at the factory for mixture.

In my case I did not have to adjust anything. Once I replaced the old carb with this one the generator cranked right up. I did not even have to adjust the idle. Not sure if all are that way.

This pump runs at about 3.5 psi, even without a regulator in some applications. Some carburetors may have different pressure requirements, so be sure to verify that this is the right pressure for your carburetor. The fuel delivery should be more than enough to meet the demands of a 2-barrel carburetor on that 4 cylinder engine.

There are three adjustment screws. 1 for idle, a needle valve on the bottom of bowl (Fuel), and a screw on the side (probable for air). However, all adjustments were pre-set at the factory. The carb was bolted on and ready to go.

I just used reducers and a mig. Get someone to tighten reducer on for you will help

I installed my new carburetor and made "no" adjustments. It has been in service for several months and has not required any adjustment. I am very happy with this product.

Same here - 29.8 as best as I can read on the dial. I am using it with a vacuum chamber and let it run for hours sometimes. It does need frequent oil changes and the Yellow Jacket brand oil (required for warranty) can be hard to get at times so stock up when you can.

Mine did not but there's must much "adjustment/setting" to be done inside a carb. Once rebuilt, the stems that are used to adjust flow would be set according to the manual that came with the original equipment. However, I prefer to just get it running and then adjust the gas & air flow... which are done outside the carb... until it's running smoothly.

There is a factory setting, however the settings are only correctif other things are ok. Fuel, air intake, compression, etc.. The answer to the question is yes.

,Dial goes to 280. Red zone starts at 200. I have a bike tire I air to 100 psi. Works great. Schumacher service is way over the top good. I would recommend you buy it. I have one and gifted one. On psi, I attempted to air bike tire at service station buttheir compressor only went to 70 psi.

Well I have a honda ruckus, its a 49cc motor. But I did some research and the 360 setting is the one that was correct for me. I would look up what your motor is supposed to run at idle rpm then find the setting on the tach that matches and that should be the correct setting.
