lektricity is simple,
You have + and _
You can fondle one OR the other.

Do not get between them, they bite.
They are separated for a reason.

Find the hot leads and all the ground leads.
Then you can figure out what the switches, devices, loads do and what triggers them.
It may be a ground path or hot that makes it do what it does.

Another good thing to know is how to do and use a voltage drop test.
It can narrow down the problem.
It can quickly find a bad/weak connection or bad wire.

Thanks, I'll print this and tape it to the inside of my toolbox!

I could not get my Asian Hybrid to idle low enough to stop the chain from spinning, and then I realized (a bit late) it is not the idle, must be something wrong with the clutch.

So I start taking it down and sure enough a clutch spring is broken. I had ordered a supply of them, but when I went to install one it became clear the ones I purchased have fewer coils (5 instead of 7). So I robbed a spring off a broken 460 clutch I saved and now all is well!

I take every AM clutch spring and throw them in the garbage and put OEM ones on.

The clutches themselves aren't bad but the springs suck.

I took this poulan countervibe stuff in trade today to help a local get his parts he needed. Traded 380 3750 p+c and 22" badboy bar and new chain and a crankcase for his 3450.

The poulan 4000 has a 3400 rear handle on it do to the 4000 handle in pic was cracked and other half broken. The 4000 recoil pulley and recoil still good but he said the flywheel had a issue. So replaced with a 3400 flywheel and recoil cover.

Craftsman 3.7 was told runs but has a break you can see in rear handle at back L. 3400 just a part saw with clean looking piston.

Will sell or trade off to folks too.
