I have an old Homelite chainsaw Model 17 Serial # 520788. It is red and green, has an 18" bar and a green cover over the head and spark plug area. It has a tank for gas, a tank for chain and bar oil, and a tank for gear lube.A few questions please: 1. How old is the saw? 2. There is a high and low speed adjustment on the carb as well as 2 other holes on the side of the carb marked H and L which have regular brass screws in the holes What should be the initial settings for the adjustments and are there any adjustments for the brass screws in the H and L holes on the side of the carb or are they just tightened until they bottom out? 3. There is a governor adjustment screw next to the top of the head with a rod from this to the carb. What is the correct setting for this governor? 4. Lastly, when the chail oil primer is pushed, it appears much of the oil comes out at the top of the chain next to ahere the bar mounts to the saw. The oil then runs down the bar and appears to oil the chain but much of the oil just drips on the ground. iIs this the way it should work? Any additional information about this saw would be very much appreciated. Thanks so much for your time. I really appreciate it.

1. How old is the saw? 1950s 2. There is a high and low speed adjustment on the carb as well as 2 other holes on the side of the carb marked H and L which have regular brass screws in the holes What should be the initial settings for the adjustments and are there any adjustments for the brass screws in the H and L holes on the side of the carb or are they just tightened until they bottom out? The H and L are just plugs. Start with the High and Low set to 1 turn open.3. There is a governor adjustment screw next to the top of the head with a rod from this to the carb. What is the correct setting for this governor? There isn't a specific setting, find what works best.4. Lastly, when the chail oil primer is pushed, it appears much of the oil comes out at the top of the chain next to ahere the bar mounts to the saw. The oil then runs down the bar and appears to oil the chain but much of the oil just drips on the ground. iIs this the way it should work? Sounds like it is working correctly. You won't have oil running down the bar when the chain is turning.

Thanks so much for the information. I really appreciate it. I got this saw at an estate sale at a very low price and because of the age, I wasn't sure it was worth getting it to run. I had it running and it seems to run fine, Really powerful and LOUD!!!. The only problem I have now is when it runs, the H and L speed adjustment screws, due to the saw vibrating, unscrew and the saw stops. I looked and there are no springs on the adjustment screws to keep them from turning. Only a small flat type of O ring on the screw itself. I'm going to try to replace them with O rings unless you have another suggestion. Thanks again so much.

So, now you have an old saw to go with the 1940 Plymouth? Yes, you need to find springs for the mixture screws. There should be a brass washer between the spring and o-ring too. Wear muffs when you run that thing ;D

Thanks a lot for the website. Terrific and full of information. As for the H and L adj. screws, the head of the screw is the same diameter as the threads on the screw. Therefore, the way they are kept in place is with an O ring which is flat on the outer edge. This O ring fits in a groove between the screw head and the threads. I put on an O ring on each screw and adjusted the screws to the initial setting and the screws seem real snug. Should work just fine. Thanks again and have a good weekend and a happy July 4th.

Are you saying the adjustment screws will not accept a spring ? Is it a Tillotson carb ?

Another reader sent me info on a Tilotson HL 104 and it is exactly like mine. I did use O rings to keep the adjustment screws snug and it seem to work just fine. Thanks for all the help. I really appreciate it.
