Here's a Super 770 I picked up. Same crank extension..
Strange looking carb. Any idea what it is?
That is a different one. Never seen a carb like that on a Saw. Was always under the assumption that all those model saws used the HL.

Looks like a Carter ND carb
That's the critter Ray. Thanks for finding the info. At least I can get a kit for it.
The saw doesn't appeared to have been used much and except for the grime on the outside from sitting in a shop for years, it's pretty clean inside. The fuel tank was drained and is clean as a whistle.
had 770, could never get the carter to work right. friend bought it for shelf queen.
I'll get to the 770 one day.
The 990 is an interesting saw. I've never seen anything like the design. Weird how the PTO side seal rides on a machined surface coming off the clutch drum. Double bearing in the drum but any chance of holding pressure or vacuum for long seems impossible. The crank bearing and thrust bearing on the PTO side look good and the seal should be any easy one to find.
The points, condenser and coil are on a plate under the flywheel. It appears that the reed(s) are attached to the front of the crankcase. I looks like the rod is unbolted from the opening and the piston drawn back and removed through the side of the case. I am going to find out.
The comp is only at 120 so I'm hoping I can find some Cabers that will fit.
Look closely at the sprocket drum bore. You should see one or two lip seals in with the needle bearings.
120psi is Great! Save your time and money.
I have two Super 75a. One pumps 110 and the other 90. Both run good.
Tune the carb to compensate for the vac leak.
A Tilly HL from another Bantam type is the best alternative to the Carter ND.
You will need to drill access holes for the jet crews.
Thanks for the info Carl! Just looked at the drum and I can see the seal.
Hi guys, Homelite guy here. My question is I have a new cylinder and I believe it fits a Remington saw. 63401 cast on cylinder. Bore is 1 7/8. Possibly for a PL4, maybe others? Has a new piston and rings also. Any information would be helpful.
