Poulan 245A help

[axe2fall]

Picked up a 245 Automatic. No history.Dont know how long it sat but it had an inch of barn dust on top. Took it home and oiled the bar and chain, put fresh 16:1 fuel mix in her and she fired up. Idled nice. After a little tweak it accelerated good so I let it warm up a little more and poured the coals to 'er. Ran great. Shut it down and checked over the chain. Filled the oil tank and tried it on a fallen green 20" hickory. I was starting to smile but halfway through it started bogging and stalled. Now it starts right up and still idles good but upon acceleration it bogs and stalls. . too many projects so I put it down but I keep looking at it .. I tend to over-complicate and dont really want to mess it up. Any sugesstions on what to look for and in which order to check things out ?
Thanks,
Andy

Probably doesn't need any more than the fuel system gone through. Clean carb,new kit, new filter in tank, lines, adjust screws to about 1 turn each and see what she does!

Stop with the 16:1, unnecessary with modern syn oils, use 50:1. Gas is crappier today then the olden days, but oils are MUCH better. You don't need to try and push sludge through carbs anymore.

Clean carb, see if it needs a kit, judgement call but most likely, won't hurt, new fuel line and filter, etc. New plug maybe. The basics first. If it sat for a long time, anything that needs to be pliable and flexible..ain't. Replace that stuff.

Great saws!

No truer words were ever typed. (except the 50:1. 32:1 is much safer and won't hurt a thing.):msp_tongue:

You may have a venting issue. Try loosening the fuel cap and see if the saw runs. Could be that the tank is not venting stopping the fuel from flowing to the carb.

Where in VA are you?

This maybe a good example of why I cringe everytime I hear someone say "the saw was found where it was sitting for like 100 years so I just gassed it up to see if it would run".

Severe damage can be done to a saw that has been sitting for years like that if some simple maintanence has not been done to it first.

In this case I'm willing to bet what happened could have been the fact that the in tank fuel line is probably broken and the filter is laying in the bottom of the tank so while it run at first, it probably sucked up a buch of crap from the tank and then plugged up the screen in the carb.

If you look next to where the fuel line enters the tank, there should be a vent fitting.

I've bought several flea market saws that had the fuel filter laying in the tank, fairly common.

The tank vent is in the cap on the 245A.

 

[homelitejim]

The fuel lines are easy to check, two pieces one going from the tank to the carb and one inside the tank to filter. One screw holds the tank top on, fuel lines are cheap and easy to replace, carb should be tuned 1 and 1/4 out on the low and high and left there.

Yep. Better listen to what Mark says about Poulans, he forgot more than most of us know.

I have been wanting to use one mix for all of my 2 cycle stuff. Picked up a synthetic blend stabilized oil that says its good for anything from 16:1 to 50:1, called Pro-mix, I think . . . still went a little heavy on the oil anyway . .Added Sta-bil for ethanol too.using 89 octane gas . . .Should that be ok?

I did a little more than just yank the rope and I really hope I have not ruined the thing. I have a 4000 that sat for alongwhile and that very thing happened.(filter on bottom of tank) Thanks for reminding me about that.
What kind of severe damage could occur and what should I have checked before I tried to start it?
I really did not expect it to fire or run . . it appeared discarded.

I am starting to figure that out, but you ALL have forgotten more than I know !

You have a great older saw there. Take Mark's and everyone else's advice and go through the saw before running them. The vent is a rubber duck bill valve in the fuel cap. If you can't see it, it probably has turned to goo.
They are great old 73 cc fairly light weight saw, especially for being all metal, no plastic. Only draw back to them, if you want to call it that, is the lack of anti-vibe features. But, I don't notice it much to be honest.

I run Woodland Pro synthetic oil at 40:1 in all my saws, young or old. No problem.:msp_thumbup: You mentioned the 4000 also. The 4000 is a saw i use more than any other. I like em so well, I have 4 of them. Here are a couple pics of them out working together.

A lot of the better oils already have the stabilizer built in. Some places also are phasing in non-ethanol fuel but I imagine with all the turmoil going on ethanol will re-emerge and maybe in a bigger way. I use Klotz Super Techniplate at 32:1 with no other stabilizer. I think I'm gonna drive a few miles tomorrow and pick up 5 gallon of non-ethanol gas for my saws.

I think I forget more than the average guy....Uh, what was the subject again?
