Hi Mike, I've Got a 7 horse Nelson Bros. but I can't do pictures. If you want I'll take a look tomorrow and try to describe them to you.

looks like this engine didnt have any special valve spring keeps on it ...

looks like a washer and pin will do the job.


thanks guys

Photo Re: Essex engine

Mike,
If you have a 7 hp Essex, you should have a Nelson Bros Jumbo engine. Here's a pic of my old 5 hp Essex.

I sold a 5HP Essex engine at the Portland Swap Meet, It definitely was a Canadian engine and it somewhat resembled a Hercules in a lot of ways. It had 90% of its original dark green paint and was ignitor fired with a Webster magneto. It was a nice well built engine.

Default essex correction

Earlier in the thread I posted that i has helping somenone work on a 7 hp Essex.

Upon better inspection, it's a 5 hp Essex and the original piston has burned up on one side. He had found one to fit it before I started helping out.

The piston that's in it now, at the top of the stroke it extends into the igniter port by 1/4 inch or so. I think it will run like this but, after time will damage this piston as well. Also I think the end wall of the piston is too thin to grind down.

any ideas ?????

thanks mike

Exclamation Re: Essex engine (updated)

As long as the rings are not exposed, unless the engine is heavily loaded, there should not be a problem
