Poulan 5200 hotsaw

[p61 western]

I'm happy so far.
All the fins on the back of the cylinder needed cut shorter for clearance so a heat shield will fit in between it and the carb, but never installed the heat shield. It sure didn't like it when that carb heated up, lol.

I haven't burned any alcohol in it yet and still need to have a pipe made.

It's going to be bad azz for sure. Love the old school builds.

I'm keeping my fingers crossed.

I think this thing is coming along nicely. I fiddled with the carb a little more, fixed the air leak, and fixed the tank vent. I'm still needing to work out a couple behavioral problems with the idle down. It may be just too much carb unless running alcohol makes a difference.
This time around I decided to run a 10-pin sprocket with 3/8 chain. I was very surprised with how it pulled it.

 

[Chainsaw Jim]

It's starting to get a little better.

It's still getting too much fuel for idle, but not enough under load. I'll remedy that and give it another run soon.

Still running the 10 pin. The wood is very dry fir.

 

[Chainsaw Jim]

Well this thing is pretty much ready for a pipe.

You gunna try alcohol? Or did that go by the wayside.

I would, but I don't even know where to start.

Acquiring the hardware wasn't what I had in mind when I made the comment.

Running alcohol you need 2-1/2 times as much fuel. Bigger fuel line normally, and gut the fuel filter.

What carb do you have?

 

[Chainsaw Jim]

It's an HR1 with a pretty big fuel hose. I was thinking it might be ready for a sip of juice as it is.

 

[Deets066]

Could be, I’m not real versed on it either. Probly know enough to fack somthin up

Rich on top lean on the bottom.
Dump the timing back and keep the compression reasonable for 20%. A hotter plug might be needed might not.
The main jet usually goes lean on gas carbs. Flood carbs cover it up.

How bout a spacer on the carb plate to hold more fuel also

Drill the inlets and tri-point the needle. Drill the needle seat.
I don't use a larger bowl to cover up a fuel delivery problem.
Case in point. Drag racing a single float Carter 750 carb. They never run out if they are done correctly for proper fuel delivery.
Edit: fixed it, twice, whew...

 

[Chainsaw Jim]

I dragged this old junker out for some hack work. It's ready for a good stack of dimes to hold it together.

I've just aquired my first 5200 and I am tickled pink. Was curious about mods I could do to improve performance without going all out like you? Any ideas would be appreciated. Thank you so much.
