They are non resistor. I've got a pretty good spark.

Then the carb is probably the culprit. I'm not familiar with Walbro's. I only have the Mikuni Powerjets in my sleds. I hope you get it sorted. These sleds are fun.

Yeah, I'm going to try another carb when I get a chance. I'm hoping I can get it running before the snow is gone.

I super re-cleaned the carb and it now runs great until it gets hot. After twenty minutes or so it gets really boggy and won't go up hills. Will still go okay on flats but stalls out at idle. It seems like it's still getting spark but maybe it's weaker( or my imagination, it's hard to tell).
Is there anything else to try before I buy new coils?

Still trying to make this run right.
Just replaced coils, timed both cylinders, cleaned carb, new belt. Compression is 110 both cylinders.
Starts good and idles now. Seems a little boggy on low end and tops out at 42mph(gps).
I've had it much faster last year but it wouldn't idle and one coil was intermittent.
What to check next??
Anyone know where to get the walbro insulator rings?

What's the difference between walbro wf-30 and wf-31?
Any idea which should be on the 77 sting and what size jet?
