Re: 40hp Johnson 1963 Carb Question

Thanks again for the help!

It’s problem solved this morning – at least one problem solved.

The high speed jet has been drilled out and buggered up by persons unknown. The slot for the screwdriver is gone entirely and the passage is larger than it should be.

I took it to an outboard shop this morning and they confirmed it.

So – I don’t need anyone to measure anymore. But I do need a carb bowl. It’s been discontinued from OMC and so I’m now stuck finding a used one. I’ll try on ebay and perhaps post here in the free classifieds.

The only other option is to try to drill and tap the old jet to get it out, and I just had a $100-$200 quote from a machine shop to do that — with an uncertain outcome.

I’m sure this is a big part of why the engine was behaving oddly.
