Experience Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. I received a scholarship from the Air Force and am currently pursuing another degree.
Question I have a Mcculloch eager beaver, 2.1ci, about 10 yrs. old. I took it apart for cleaning, etc. (got a little carried away i guess); the handle (rt. side looking to front of saw from rear) contained 3 parts-throttle trigger, safety lock for throttle, and a spring, The spring is approximately 2-2.5 inches total length, approx. 90 degree bend, 1/2 inch coil, in center, w/ 2 full loops, straight on shorter side, longer side with small dogleg and bend at end. I assume the spring returns the throttle to idle after starting. As the pieces unexpectedly disassembled self b4 i could glom the schematics of, and I've tried numerous config's to reassemble, I cannot come up with sensible location (it seems to fit the post in front of throttle only) and mechanical function for the spring. the mechanism (throttle , lock) will work without, but needs manual return to unlocked throttle status.any ideas? thanks.
Answer The srping is used to hold the throttle safety lock in place, not to return the throttle to idle.
The 90 degree bend, if I remember correctly, just sits under the safety lock lever to hold it up.
I'll see if I have a repair manual for it but we got rid of most McCulloch stuff years ago.
