OC-4 will only run on wrong firing order?

[Doug424]

I have found a lot of good used model A u-joints at flea markets and on ebay. A source for new ones that some people use is: http://www.snydersantiqueauto.com/1620  that's the kit for $43,, they sell the whole joint for $95 So, what you found sounds about right.

I have had similar experiences with NAPA, although other's have great experiences to report. Depends where you are, I guess.

Thank you for the U-joint information. I haven't found them any cheaper, myself.

On the rubber boot, I sell them for $10 plus probably about $3 shipping ? certainly no more than $15 inc. shipping, wherever you are in the US.

If you have a dedicated drive shaft shop in your area, they'll probably know more than an auto parts store. Especially for old or unusual applications. Around here we have a place called Point Spring and Driveshaft. I've had them rebuild several driveshafts for me. It sounds like you found a good price on the Model A u-joints, but you might want to check with a local shop if you have one.

So there I was.... trying to get my "Chocked full o nuts" OC3 running and the wife starts reading me this post, In two wire swaps it was running!  After 3 days of trying to make sure my OC3 was set up like the book. Now it just purrs..... Thanks everyone.

Great news! Glad you got her working!

I knew my IXB 3 had come from another device since there's no Oliver bell housing badge like plate with the OC3 serial on it. The engine crankshaft has the extension to run my hydraulic pump. But does anyone know why Grants and my IXB3's use the other (wrong) firing order?

[oliverchris]

I assume because you did not set up #1 on the magneto rotor with the upstroke of the #1 piston.

I put a spark plug in-line neon light on the front (number one) spark plug/cylinder. I rolled the engine by hand until that (front #1) plug wire flashed with light, it's fed by the wire off of the top R hand wire from the magnetos cap (distributor). The SPRK mark is in the flywheel timing hole, and that all coinsides with the white bar in the he magnetos timing window. So could I still have the engine mechanically 180 out? Or is it 90 degrees? I timed the engine with a timing light, on the SPRK mark in the window, on the cylinder one plug wire. It idled ok, but It ran like crap loaded, but it ran, it didn't like to run loaded in gear or moving the blade up and down timed that way. Later I timed it closer to TDC and it purrs. All with an incorrect firing order?

I'll play with it more after my compression tester comes in.
