Max rpm for 42 cc Craftsman chain saw

[Outlaw5.0]

I need to give the 42cc Craftsman beater saw a tune and need to know the max rpm. Also how to remove the limiter caps?.

i would say about 200,000 rpm and then go buy a real saw

Already have a stihl MS460, the crapsman is for small jobs and dirty jobs. The saw seems to be really screeming lately, just want to check the rpms.

get a tach, sometimes saws run great before they die

I was able to retune it without pulling the limiter caps. I set at 13,000 rpms, it four stroked at 12,900 rpms.

Congratulations, and goodonya for not letting some of these guys get under your skin.

I have one that I bought at a yard sale for $15, and it gets some rough useage, and keeps on cuttin'

Thank you. Get yourself a good chain(not the non-kick back crap) and mod the muffler, it will seem even better for the $15.00!.

Well I did a few more mods to the muffler, cut a few holes in the baffle, and one more in the muffler case. I was able to increase the rpm to 13,100 and its still four stroking, but ran out of adjustment. I need to remove the limiter caps and see what happens. I also have a few mods in store for the carb and air filter cover. I realize its a cheap junk saw, but its still fun. My Stihl MS460 will get a few more mods next after its broke in slightly more.

I second that!! I've got lots of saws but the little Craftsman comes out now and again. The thing runs like a champ. Mod the muffler, richen it up, and you'll be impressed.

Is this the same saw that you thought was getting tired after using up four chains?

Yes, maybe it now runs like it did when it was new?. Anyway it runs better. I'm trying to get some experience on this saw before I really tear into the MS460. After buying the MS460, I can't afford to buy a MS361 till next year, so I need the crapsman to last.

My 38cc poulan exhaust gasket needed trimming because the opening was too small. The next time I mod this style muffler I'm going to try drilling the baffle holes on the top down through the bottom. Did you open up the two small outlet louvres in the back?

No I left those the way they are. I put a 3/8 hole in the right upper side and out the front on the bottom. I also drilled out the baffle holes larger and added 4 holes on the other side of the baffle. I may drill the holes out to 7/16 after I pull the limiter caps.

Did you use the dimpled area in the bottom front for a outlet hole?

Yes.

Have you thought about making a screen type air filter instead of using the oiled foam type?

Have you thought about making a screen type air filter instead of using the oiled foam type?

No I have not. I have thought about drilling small holes in the back of the cover and epoxying a screen on the inside to catch some of the dust/dirt/shavings. If I could get a Green Weinie or K&N type to fit, I would try that. Eventually I will raise the compression, one step at a time. I love to tinker with mechanical stuff, so this is fun!.

4 yrs ago I bought my 1st chainsaw 42cc craftsman with 18" bar and safety chain--I hated the thing at 1st--I had trouble starting it and then the rope came off of it so I had to tear it apart to reattach it and a few days later it broke off again--so the next time I fixed the rope I split the end and tied it around the tiny little screw that held it in place and I used crazyglue on it--yes I i did--LOL but its still on there


after re gapping the sparkplug--I never have trouble starting it--this is a lower compression saw isn't it?

anyway I kind of like the saw now for the small work I do--its light and starts everytime--I did almost kill it though cutting up a large appletree

I just need to get a 16" bar for it and better chains than the safety chains


I would also like to muffler mod it

are there replacement cylinders and pistons to get more CC's out of it

I'd spend maybe $100 on it

i have a 2250 poulan that i modded the muffler took the baffle out and used it for about 5 yrs.after modding the saw has never not started when i needed it.
