Have a Homelite XL-98C multi purpose saw Ut # 050158 and serial # HI2430319. What is the fuel mixture ratio?

A google search produced the link below.

You would be fairly safe using a 2-stroke mix similar to machines of a similar age, design and purpose if you don't find what you are looking for.

I bought up a lot of Homelite parts when dealer went out of business about 20 years ago and have had interest in them since. I have worked on a few super xl's but cannot tell you for sure the fuel mixture but believe it probably changes over the years from 16-1 to 20-1 saw on internet one person claimed that that ut number used 32-1. Don't believe it would make any difference as long as you used good grade 2 cycle oil and it would not smoke near as bad as 16-1. One person on internet claimed that he still had the saw his Dad bought new in 1967 or 68 so they have been around that long but at that time I do not believe they had a UT number on them.
The cc is 57.4 and weighs 13.14 lbs. With 24" bar.

Changing a spark plug rarely fixes a no start problem. You need to troubleshoot the saw more. Do a search on youtube or google about how to check for spark and how to check to see that the carburetor is getting fuel.

Run what ever fuel/oil mix you are comfortable with. A run lean condition is most often caused by an undetected air leak leaning out the mixture to failure. A couple of ounces of 2-cycle oil will not prevent its occurrence. If an owners manual (OM - I tried) is ever located it likely says 32:1. Most modern saws recommend 50:1:

Oil Mix Ratio:

In the early to mid 90s Dolmar, Echo, efco, Homelite, Husqvarna, Jonsered, Makita, Oleo-Mac, Red Max, Ryobi, Shindaiwa, Solo, Spear

40:1 mixture for the fuel:oil ratio.16:1 will cause your saw to barely run(if at all) and if it does, will fog out every mosquito for 4 blocks. You can use any reputable 2-stroke oil, though stay away from outboard engine oil. Get the good stuff that says Stihl, or Husquavarnah, or something like that. Even the Homelite stuff is ok. The oil tank takes regular bar and chain oil.

The header says that it is an electric saw which would only require bar oil. A 2-stroke gas engine, however, does require fuel mixed with a modern saw oil at 40:1 ratio plus bar/chain oil in it's own tank as well. Always premix the fuel and oil in a separate can and shake well even before filling the saw. Hope this helps!

40:1 is about right. Be sure to use modern synthetic oils made for saws and premix thoroughly before adding to the saw.

32:1 according to this.

Thank You for using FixYa.

An XL from that time frame recommends 32:1 here:

If my saw it would be adjusted for and operate on 50:1.
1 gallon of premium fuel to 2.6 ounces of quality 2-cycle oil.
4 liters of premium fuel to 80 milliliters of quality 2-cycle oil.
