Re: Can’t figure it out!

I realize this is an old post, however, as a general rule, if you increase your rpm and your oil pressure drops that means it you’re low on oil. Another indicator is if you pull back on the throttle quickly if your oil pressure drops, it means that the oil is running away from the pick up and when i...

Re: 1941 K Distributor Cap and Rotor

The 12 V per Tronics module in the I GW distributor works quite well and reliably. The 6 V version has problems because the module Ceases to function properly at 5 V. The 6 volt version is also susceptible to noise coming from the Generator. We have come up with ways around that however your best lu...

Re: KL Generator overcharging

Has your generator been converted to 12 V. If not you can get an over voltage condition that can damage your batteries and your ignition system. If it has been converted then the third brush probably needs adjusting

Re: KLC carb (Zenith 11168 / 552M) mix screw adjustment

A good starting point for the high speed adjustment is three turns out from fully closed. For the idle mixture screw one and a quarter turns out from fully closed is a good starting point Your engine should run well with these preliminary settings

Re: Adding a Temp gauge to a CC 105hp "K" engine

I don’t think it much matters whether you use an electrical gauge or a mechanical gauge that uses a capillary tube. Your big challenge is to find a gauge that matches the cosmetics of your other gauges and getting the plug out of the side of the head. Once you’ve accomplished that either one will wo...

You need to make sure your test connections are good. I will get back to you Monday on the part number.
An A circuit requires you ground the fields a B circuit needs power to the fields. It started out as a Delco vs Prestolite thing.

Re: Riviera KBL Engine Oil Pressure Gage Connection

No all the oil goes through the oil cooler.
If the engine was assembled properly there is a pipe plug under the oil pump which directs the flow of oil out to the side of the engine then through the oil cooler and then back into the main oil galley.
