Hi guys.
I've got JC Penny/ Eska 1975A 5.5hp with the Tecumseh AV600-643-20b power head.
With the help of you guys I got it running (needed points set, new coil and carb rebuild). got it running Tuesday night and after clearing its throat it ran real well.
So I came back tonight to hook it up to the water hose and see if the water pump works (it does.... thats the good news).
The problem is; after running great the other night now it 'pulses' (brap brap braaaaaap brap) also, it would only run with the choke fully engaged although it would smooth out a little at full throttle.
There's an outside chance of a loose electrical connection and I'll check for that but it seems rythmic and I suspect the carburetor. Question is; what could be wrong if it ran so well the other night? I've heard that the little red 'fuel pump' bladder is notorious for going out on these but I've also heard that that is normally associated with a backfire, which I did not experience. BTW I've also heard you don't need the fuel pump if you are going to run it off of the on-board fuel tank (gravity feed).... Is that true?
Any ideas?
I really do appreciate the help.
