This one came in in February, customer said entirely his fault. He did not read the instructions correctly and left it on high idle with the brake set for several minutes to warm up. Very low hour 291, the clutch itself was overheated to the point the clutch springs were totally slack and the...

Thanks all, I will try the solenoid and filter and report back on Monday. Mark

I have an MS362C in the shop, customer says it falls on its face under load. The label on the handle says it is version 3.0. I when through the calibration procedure; 30+ seconds in triangle with the brake on, then release the brake and pin the throttle open. I could hear it hunting, rev...

Rather than tear the engine completely down again, I swapped the flywheel and starter shaft from an 850 that allowed the cover to fit correctly. It was also necessary to space the coil out 1/4" to keep the laminations properly aligned with the magnets on the flywheel. I used a threaded...

I put a note in the small parts bin with the dowel pins so hopefully I remember to check these in the future. I also noticed there are 4 different versions of the bearing insert used on the 10 Series saws over 57cc. It's hard to confuse the ones with the retaining rings vs. the ones...

I was putting a PM800 together and learned a valuable lesson about the dowel pin (110851) used to locate the bearing insert on the PTO side; in spite of the fact that the IPL from 1973 through 1992 call out the same part number, there are in fact two different length pins on various models...

Shane - I sent a message. Mark

I just make some blanked off "gaskets" from Buna N material and use the carburetor and muffler for my block off plates. Mark

You might as well make those parts Chris, you will be needing them again for additional projects...

I'd be interested in knowing more about that one, I'm not of Facebook but I will be passing through PA in November. Mark

Bottom line of the coil & flywheel testing: Points ignition (Mini Mac) uses "IGN" flywheel 91961/94513/94737,217673 Early brown & large white electronic ignition modules on the 300 Series saws use the same "IGN" flywheel as the Mini Mac models Black SEM electronic ignitions use "CDI" flywheel...

Sorry Ed, had your message prepared and never sent it, check your in box now. Mark

Many of the black, SEM coils came to me mixed together, and in a few instances had incorrect part numbers on the boxes or bags. A few of the brown and white coils came without part numbers and not being as familiar with the different models at the time, I did not know what they should fit. I...

94513, IGN flywheel 219211 CDI (or BB) flywheel Mark

Son Jeff and I spent some time yesterday trying to organize a mess of electronic ignitions for the small McCulloch saws. I wanted to check/test some different coil and flywheel combinations and came up with this set up using a 300 Series short block, degree wheel, and timing light. I had to...
