Don't make me chop you
With the small Sthils being some of the top threads in the chainsaw section for the present time I thought I would put this up to show some of the former rear handled or AVP models that evolved into the rear handled MS 200. Most of you guys may or may not be familiar with these saws. I have always been somewhat of a nut when it comes to these older 020's. I try to make them as good looking as I can with the correct body parts, engines and carbs according to the markings on the gas tanks without going overboard or hurting to much in the pocketbook.
Here goes, I hope my facts are correct.
Pic 1 and 2 show the first 020 AV. AV being anti-vib. The P on the gas tank was the professional model or the rear handled version. The clutch cover also had a P on it but it came off cleaning up the saw. I have no idea why or how this notion came about. To me it is backwards, the tophandle version would be a better choice for a pro climber.
The 020 AV(P) has a 38mm engine. Which was 32cc or 2.0 cu. in. with a simple point and condenser ignition. The saw came with a simple hard plastic hand guard that is very brittle and easy to break. No rubber on the round front handle just bare metal. Carbs were usually the Tilltitson HU. These saws came with 1/4 pitch chain with 12 or 14 in. bars In it's day it was probaly a deluxe model to have.
Pic #3 is another 38mm AVP which is basically the same saw only with a electronic ignition and a some rubber on the front handle. The electronic ignitions were just simple transistorized modules about the size of your thumbnail that took the place of the points and condenser and was located under the flywheel in the same place as the points and condenser. The electronic ignitions aren't all the same in the 020 line-up. Some have what I think would be called a capacitor discharge ignition,again under the flywheel, others have the trigger module mounted with a right angle bracket to the coil on the outside of the flywheel. This type ignition was more common on the Super's. I imagine this is for keeping the module cooler. Carbs on these saws could again be Tilly HU or the Walbro WA.
I tossed that 1/4 in pitch carving bar on this saw just to have something different and to make the saw look nice. It is one of my better ones.
Pic # 4 is the Super AVP version of the 020. I wish that tag on the tank was in better condition but it is the best I can do for now. Carbs on the Super's were usually the Walbro WT or WA. This saw is a close relative to the present day MS rear handle 200 with a working chainbrake. The engines are almost identical. The Super version of the 020 is a 40mm or 35 cc or 2.13 cu.in. The MS has a 35.2 cc or 2.15 cu.in. engine. I have been inside both engines the 020 Super has a very noticable longer connecting rod than does the 200. The transfers are different, the 200's are open while the 020 is closed. I have never ran the two saws side by side but I think if you were to get down and dirty in a bury the bar in hardwood type cut the 020 just might edge the 200 out by a smidge. The 200's seem to fall off when you get into these types of cuts. My memory of running the 020 Super's climbing and from a bucket might be clouded as I don't remember the Super's falling off in cuts like this. The 200's definately have the 020 beat for short quick cuts hands down because of their faster chain speed and higher revving. The 200 is also a much nicer saw to run, it is lighter and better balanced and as Butch has said more egronomic. The feature I like best on the 200 is the contoured front handle. It isn't round like most saws. Feels like it is custom made for your hand when you grip it.
Pic #5 just shows the AVP 020 Super alongside my rear handled MS 200, sort of a past and present kind of thing.
Hope this wasn't too boring for some of you guys. Like I said I just have a soft spot for these 020's. I hope my info is also correct as parts on these 020's interchange readily between the early models up to the more modern type's.
