Ht70 stihl pole porting?

[pro94lt]

I took a ht70 in for payment put a new carb, fuel lines and got it going, I see it's got a pro style cylinder and wondering about porting... Anyone ever ported a ht70? Might try a base gasket removal first...

It would give it torque. I bet the muffler is all choked up

Let's look at the jug if your serious. Pics.

I've not got the jug off yet the muffler bolts are a dirt dobber den... It's a open port dual transfer engine and the bolts go in from the bottom and looks like the cylinder is threaded for the head bolts. I've first got to clean the bolts off before they back out through the cylinder threads...
