Davefrombc. Thank you. I have a degree in electronics and my Father was a master mechanic. I worked with him from time I was knee high to a grasshopper lol. I worked as a mechanic in service on hellicopters and then on trucks and cars for a few years. Then I decided I had enough of low pay(back then it was low) so I went into Industrial electronic. I am retired now, got burnt out doing electronic repair, 45 years of it is way to long and have a hobby that is trying to turn into a business of working on small engines. These electrical prints, ECM/CDI electronics are simple on small engines though the manufactures are tring to make them complex so shade tree mechanics can not work on them. I started out just doing some work on friends mowers and Atvs. I have never advertized but now have about 75 - 85 people that use me to repair everything, mowers, Atvs, motorcycles and Boats. But I draw the line and work only on smaller engines. I have had people wanting me to work on Trucks and cars because they know I know how but I am to darn old to do all the crawling around on them. As for parts and manuals I use the internet to hunt down what i need and sometimes I have to purchase those manuals.
