Hey there Huskyman, the Super EZ auto is 2.5 cubic inches and has a 4 reed pyrmid reed cage. The stalling at an idle is probally the carb. This model is prone for carb problems. The good news is that this saw shares the same bars as the smaller Husky's. I have many of these saws, I have one with a 13" Oregon Micro-lite bar that runs 95vp (.325" Narrow Pitch) with a 9 tooth sprocket. This set up is good for everything under 8". The "standard" on these saws is a 16" bar with a 3/8" full chisel chain, sporting a 7 tooth sprocket. This is the set up I suggest you use for an all-around type application. I am unsure of the horsepower as I have no Homelite literature that spells out horsepower. I feel that since the saw has a lot of torque, it doesn't matter what the horsepower is. These saws were produced until the mid 80's, if your saw has a plastic starter cover it was built in the 80's, if metal and it was blue I'd say late 60's, if metal and red probally 70's Good luck and let me know what you decide.
