On those odd supposidley tamper resistant screws you can often turn them with a piece of small plastic fuel line .Try as they might the have never been able to make things totaly tamper proof .

Well the mac wasn't a mac but a gmc (chinese crap) will see if I can get it to run might get a few bucks for it If nothing else I think the bar will fit the jen feng macs   Also got a non running 011 or 010 stihl has no compression but usable parts saw Or just ebay it and turn it into a mac with the cash

You can probabley throw a set of generic rings in those little Stihls if the chrome isn't shot and give them a new lease on life .

They are what they are but they aren't bad for little saws .Ha they won't win any races or slay many oaks but they will cut firewood and trim apple trees in the back yard . ;)

Hey Al was having a fiddle with the two junkers tonight the gmc runs sort of have to try sort out the carb a bit races when upright drops back to a normal idle speed when layed on its side. The stihl I think may well have worn the barrell as the rubber plug that fills the gaps where you slide a screwdriver in to adjust the carb is missing thus allowing a pile of crusty crud to enter the carb chamber but as you say rings may do it cheers

So is this gizmo a regular brush mower or a wheeled string trimmer ?

I just recently bought an old Whipper brush mower for little of nothing to get the 8 HP engine to fix my buddys log splitter .From what I gather this is the same design the DR brush mower uses .Since I have a couple more large Briggs engines laying around I'm thinking about hanging another engine on it .Those things are supposed to be tough enough to mow down 1 1/2" saplings .

One of those 8HP Briggs engines I picked up also for a song  was a go kart engine .I pulled the head and watched the valves and it definatley has a reground cam shaft .

Now what they do on a kart engine is turn down about 1/2 of the stub end of the 1" crankshaft to 3/4" so they can use a Comet clutch .As luck would have it I landed  a stock unturned crank with a rod and piston off of flea bay for less than they get for  connecting rod which I need to repair another engine .Geeze between chainsaws and Briggs engines I'm up to my hip pockets in small engines .

This thing is just a regular string trimmer when I referred to the 2 junkers that was the saws I was given in return for getting the strimmer running  What was supposed to have been a mac wasn't
