What's on your bench today?

372AT

 

Just got done running a little whirly gigger inside one of these poor things. I'll see how she runs tomorrow. I've made no ignition timing mods, so curious to see how she will respond to them tomorrow. Adjusting the carburetor is just a good time on these things.

We'll see how she comes out. There isn't a lot you can do on the intake of these unless you want to defeat the strato. This is a work saw, so I didn't want to go too crazy with it. There's some timing added to the intake, very little done to the exhaust port, muffler gutted, transfers raised and directed a touch, and lower transfers had a lot of work done to them, as well as the base of the cylinder to match it to the chassis.

 

I'll adjust the timing advance tomorrow to see how she likes it.

 

Just noticed I said it was a 372AT. I meant to say 372XT. This will likely be the last one I do - virtually every porter I know that I asked for advice on a 372XT said either

1) I don't do em if I can help it - they eat rings, or

2) lathe work and defeat strato to get real gains.

 

So, yeah, I just will go a bit conservative on it, gave it a lot more open exhaust, more transfers, and some ignition timing if it helps. She has to like it at least a little - she's half a turn out on both screws and still jis nudging the rev limiter.

A bud of mine, whom I have owned a few ported saws of his, is a Husqvarna dealer stateside.

 

He's had a '572AT' in his hands for a short while recently.

 

He liked it.

 

That's all he would tell me.

Your first problem is its a Stihl, your second is your clutch drum, replace it, the drums were mis-aligned when drilled

If you can get hold of the metal caged needle bearings, they are significantly stronger than the fibre ones!
