Here is the bow section from the 1977 245A IPL.

No kit is listed in it.

Got ahold of this split boom trimmer with saw attachment. Replaced fuel lines, primer bulb, cleaned carb and put in a new kit. I can get it to fire but it will only run for a second or two then die out even if i throttle it. I tried messing with metering lever in carb and no dice. It has those dumb spline carb adjustment and the tool is supposed to be here tomorrow. Only thing Ive noticed is it will run a moment long on full choke, if you half choke or no choke it the thing speeds up and dies.

Anybody have any ideas?

Those screws are only dumb because you dont have the proper driver for them yet. When you do you will change your mind, there the best setup going.

Not being smart here but you have to read the starting instructions on that power head and follow them exactly if you expect it to start correctly.

Sadly I did follow the instructions. It just wont run the 10 seconds on half choke to make it to
choke off position on choke. And if I move it over to choke off it just dies. Only thing I can think of is there were two diaphrams in carb kit that were the same. One was black and one was a white fibrous material. I put the black one in the carb. Would that matter?

likely so. do you have the old ones that came out? lots of the kits use two such pieces that work together... one makes up the seal between the ports and a thin one that acts like flapper valves.

One in the carb was the black one. And it just had two pieces, the gasket and the black diaphram.

Another thing ive noticed is when I pump the primer bulb gas doesnt get to bulb. Does that mean anything?

First thing that comes to my mind Aaron is forest service, it being Kalifornia and all.

Could very well be Jeff. CDF headquarters is in Sacramento, where this saw came from (and where the state surplus auctions are). This saw would have had to have spent its service life on a shelf however, as it doesn't have that 'beat' look to it. My PM700 used to be a local county saw, and it is in similar shape.........so it is possible. Hope I can find an IPL for this very late 306A. That might answer a few questions.

What do you think about that?

A lot of people have trouble putting the fuel lines back in the right place. I was given an almost new looking Wild Thing because he didn't know where the fuel lines were supposed to go. It ran fine when I turned them around...

Yup, my first overhaul with a purge bulb system was a Mac 2014. Lines were just so much crumbled macaroni. Found many, many different ways to hook it up.

Primer is a misnomer.

Some of those saws never did run right even when hooked up properly. Since I didn't want to spend too much time on them I removed the bulb, blocked the line from the carb and fashioned my own tank vent. Most of the saws ran just fine. My Husqvarna 322L weed whacker and my Poulan Pro weed whacker are examples of this and have been running fine for some time now. I also own a Craftsman 2.6 18" saw that I "modded" this way. I suspect the problem might have been a defective primer bulb but I bought a new one and tried it and it didn't help. The new one may have been defective too for all I know.

So im an idiot so what . Whats really strange is 2 sizes of fuel line and larger line goes to smaller fitting and small line goes to larger fitting.

Two more clues to the puzzle. It may very well be surplus, as a newer AV model would have been my choice, being a county saw isn't a production model, and can be set down at any (or most of the) time. Wonder if there is anything in that muffler spec list from the forest service?

The 3400 and 3700 had started production around the time my saw was built. Those are of course AV models that will do the same job as the 306A. With the amount of time that it takes government agencies to draw up a list of requirements for an equippment order, it could be that they'd gotten a shipment of their 'special' saws right around the time that they became obsolete. If that's what happened, I would have liked to have gotten their load of spares when they changed to the 'next' saws and cleared these out. I haven't seen any inventory numbers engraved into this saw (like my ex-county PM700 has). There is a large sticker from a small engine shop on the flywheel cover. Maybe there's an inventory number under there. I usually like to keep saw shop stickers on old saws (as a bit of history), but this one is big and ugly................and might be hiding something I want to see. I'll see if I can get it off of there this weekend.

 

[8433jeff]

I was thinking a heavier brand, not another newer Poulan. Contract bids can be funny things. A vertical cylinder saw would passed the fire safety deal easy. Look (feel) for a number under the sticker by touch, and if felt, only then would I pull off the "history". Otherwise, it looks like a little used gem, and maybe a private party got inspected by USFS, or asked about cutting on USFS ground. Ask the saw in a quiet moment whilst drinking some PBR or that brown liquid you favor in a short glass and it may tell you.

 

[Eccentric]

Jenn already suspects that I talk to my saws...

 

[BroncoRN]

Got fuel lines turned around and apparently low side was about 3/4 turn too lean but got it all tuned up and it's a neat little saw for $65!! Next stop will be dads yard!!

71A won't start

Been working on a 71A that has been sitting for a long time. Took the side cover off, and the carb was spotless and even the fuel lines were good. Took the Tillotson apart, it was extremely clean inside, too...........gave it about 4 cycles in the ultrasonic cleaner and installed new diaphragms and gaskets.
Put everything back together and tried to start........pull, pull, pull......nothing. It's pulling gas through the line to the carb, but won't start.
Spray some gas in the carb......fires right up, but dies as soon as the gas is burned. Any ideas as to what to check on, in the carb?

 

[DSS]

So I finally got a 3400. :msp_smile: Apparently it runs well, but is missing the air filter and top cover. No pics cause I don't actually have it till tomorrow.

I understand air filters are available, where is the best place to get them? And would anyone have a top cover?

 

[MS460WOODCHUCK]

Is the PP380 and the poulan 3750 the same p/c and will the 3750 p/c bolt directly on the PP330?
