Homelite Super XL chainsaw

Hi All,I am trying to set the points, I assume that I bring the piston to the top and set the points from that position on the shaft,correct me if I am wrong.
Thanks

I think I have owned that Homelite Saw since around 1977 . . . . and I have never had to adjust the points.

Looking in my service manual though, I read:

"Note the following on breaker point equipped models: Breaker point gap should be 0.015 inch. Air gap should be 0.008-0.012 inch and may be set using Homelite shim stock No. 24306. Ignition timing is fixed at 23 BTDC and cannot be adjusted. Breaker point gap must be correct, however, as it will affect ignition timing if incorrect."

Hope that helps more than it clouds the issue for you.

So that would seem to say that if the piston is at TDC the lobe on the shaft is how to set the point gap,I guess.

There should be a lobe on the shaft that the points ride on, you position the shaft so it has the points at full open position, you set the gap there. Have a good one. Geo

What model is the carb? I suspect there will be some letters or numbers on the carb itself.

The only numbers I see without removing the carb are, Homelite SCD 8 and 119

You'd have a high (H) and a low (L) screw and a throttle stop screw. Get it running and warmed up with the right gas/oil mix. At idle set the L for max rpms, then at WOT set the H for max rpms. Now check the responsiveness of the throttle from idle to high rpms. It should crack right off without hesitation. If you're good there, go back to WOT and turn out the H screw for a slight rpm drop. This gives you a little richer mix for more lube and load.

Now, at idle set the throttle stop to get the chain just moving, then back until the chain stops.

If you're running the saw in hot weather, either set the H screw for a little richer mixture or run more oil in the mix. For a 1977 it probably has a 32:1 ratio. For today's oils a 50:1 is pretty common. Go back to the 32:1 mix for hot weather.

Sounds like some carburetor tuning is needed. Turn the high speed mixture screw in a half turn or so and see if that helps. Soemtimes you have to rev it up and blow out all the old oil and residue if the carb seeped over time.

The carb was removed and clean,which really didn't need it,I'll try turning the HI needle valve in a bit,just never saw this kind of grey wet smoke.
