038 magnum

[giver]

I have had an old Stihl kicking around for about 5 years and decided tonight it needed to live again. I thought it was a 034 but after pulling the cylinder ( it had been straight based) it's a 52mm bore and about 34mm stroke so I'm thinking it's a 038 mag I just need clarification please.

Pictures will help for clarifying the model.

I'll try and get some up tomorrow but there's no tags anywhere on it

034’s look totally different to 038’s.
People will be able to tell you right away from the plastics and shape.

Just looked it up, looks like a 038 and has a 52 mm bore so must be a magnum

52mm should be.

I've never tried a 038 will they run with a 044/440

52mm X 34 is a 038M

52mm X 40 is an 064

Save OEM cyl if you can, stay away from Chi-Com "Chinesium"

I think the cylinder will clean up fine, just ordered a meteor piston for it. I thought about the LRB cylinder and piston kit but not sure about it so I'm going to use the OEM

More low down grunt than a 440. 440's rev harder and faster. I preferred my 038 mag contrary to popular opinion. Was built like a tank.

You'll like it if running well. Done right will last a long time. Mine chugs through hardwood with a 25" B/C

Check over and/or replace hoses/filters/rubber parts (intake boot/AV mounts)/carb kit. Worth doing seals that come in a gasket set.

I think I might do some light porting and a MM. I traded my ported 372xp for a f250 in the spring so I'm in need of another 70cc saw

Is there any decent AM cylinder kits available for 038 I have another one but it's a super that needs a cylinder?

 

[Adam08ski]

Meteor one make one I think.

I found a meteor piston but not a cylinder, but I haven't looked very hard either
