I retired two and a half years ago after driving for Roadway express for eighteen years. Every one needs something to do even if they are retired, so last spring I went back to college. I always done my minor repairs on my equipment that I used around the house and place. So I took a twelve hour course on small engines. I started working on chainsaws not to supplement my income so much but as a hobby. Then I found this site about six months ago and started with page one and have read every post that had a title that I thought would be of interest to me and some that did not. I have learned a lot but I do not retain things well at my age so I printed the ones that I thought I would use and have two note books full. I thank every one for all the post, some are educational, some are interesting and some are not. All this being said to soften every one up. I know the opinion most every one has on poulan wildthings, but since I started working on saws my neighbors bring all there problems to me. The saw in question is hard to start (15 pulls). I have checked every thing I know to check and some things I don't know ( tank vent, new plug, gas in carb, gas in cylinder, checked fuel filter, choke on, choke off, use prime button, don't use prime button. Once you get it cranked it will usually start the next time without a lot of trouble. The only thing I found is the spark is yellow and some time I can not see it (I broke my neon tube tester and checked six places in town today and no one had one). It is very hard to pull for a small saw and will kick back sometimes. I took the fly wheel of and it has a built in key that had .002-.004 slack in it so when I put it back I moved it so the time would be retarded and it helped on the kick back. I have no way to test the coil. My question is should the coil be bad on a saw that probably has not been use over ten hours.
The other question is about an 021 stihl that another neighbor brought me in a bucket (good neighbor). The oiler had quit and his sons had dismantled it and then they were lost as what to do. I got ever thing back in the right place and found the problem. Some one had put the sprocket on and either had not put the wire that runs the pump back in the grove on the sprocket or the wire had got bent down so that it rubbed against the plastic case and rubbed a hole where the oil pump goes through the case and it pumps oil into the area behind the clutch. I fixed this with JB weld (I don't know how long this will work). Now it still want pump oil. As I said before I got it in a bucket and this is the first 021 I have seen. I put it back with the hole on the side where the hole is in the case and pushed it up until the end meshed with the plastic gear on the crank. The plastic fitting that comes out of the tank and fits over the end of the pump has a square opening so I am wandering if I did not get all of the parts (I have had to send him back a time or two to find parts). Any help would be appreciated. Tom P.S. I bought an 028 Stihl WB yesterday with a scored piston and wander if it would be economical to repair it.

can't help on the 021 oiler but on the poulan 2 things spark should be blue next yes a caoil can fail but it is not the most common things next do a leak down test for air leaks in the crankcase/intake thats about the first thing to do in a saw.
