Contact me if you have any questions.

Hello and welcome to my webpage.

My latest project: a hot air engine.

See the recent acquisitions.

I now have 25 Jacobson engines and some factory records which list all parts used on all the engines Jacobson made; Bullseye, Maynard, Spotless, Moody, and Unito. I specialize in engines made in Warren, Pennsylvania and in gas engine restoration. My collection includes Jacobson Engines from 1 1/2 hp to 16 hp; Straightline, Struthers Wells, Fairchild Betts and RG Shiley. I have the means of making most small parts for Jacobson Engines including ignition and governor parts, oil shields and mufflers. I also have literature on Warren-made engines.

I am always looking for basket-case Jacobsons or Warren-made engines and I am looking to borrow a 15 hp crank guard and 12-15 hp muffer to make patterns. I am still looking for a Type "T" thermoil.

I do not make parts for Jacobsen lawnmowers. This is a different spelling and a different company.
