That's a shame about the coil as they rarely fail, I've had the wire break inside the insulation before.

For reference, I checked the older style coil on my Chug-A-Saw, it measures approx 2.4kΩ, from memory the later style coils (made by Phelon) measure much higher at around 6kΩ.

 

Here are some pictures of the vertical gas/fuel tank used on the Chug-A-Saw, it is the same size as the oil tank.

 

I was going to suggest making a tank using coffee tins, but they are slightly bigger in diameter and won't fit the space available.

 

David

Hello David. I will double check the coil in case I was having a moment when I checked it! Points wise ideally I need the main section not the pivoting arm as the contact is missing from it, don’t ask me how as it wasn’t under the cover when removed! 😀. But the contact is pretty rough on the moving arm too so ideally a complete set but I may be able to use a contact from some different points if you have none available. I will need a governor vane too yes as it is missing. I can make the cylinder gaskets too no problem. Many thanks. Andy

Fuel tank?

 

 

 

Or maybe find a can of something to use as one. Something like this? Or the top can be cut off with one of the rim cut openers and solder it on to a taller can of the same diameter?

 

The tank in the pic is the short one that came with the second engine I bought. It is a short one which I could use temporerily but will try and find something similar to the original for the saw which David has kindly put the measurement for me. I am sure I can find something like in your pic easily enough. Thanks Andy

I should be able to help, is the coil open circuit or just need the perished rubber wires sleeving?

 

I'm fairly certain the vertical fuel tank has the same dimensions as the horizontal versions (oil tank on this tool).

 

The cylinder gaskets will probably leak if re-used, if you need to replace the shafts seals the only option is to use O-rings of the appropriate size. If you strip the engine down it's a good idea to use a large tray to catch any bearing rollers that may escape.

 

Have you done anything with the gearbox, they originally used oil which either dried out or leaked out, they eventually changed to using grease.

 

David

Hello David,  the coil is open circuit sadly. That’s ideal, I will find a similar tank or oil can etc. Are the cylinder seals available anywhere? and I can find o-rings for the crank no bother. The gearbox is all that I have left on that engine at the moment but I will be popping the cover off and cleaning it out and filling with liquid grease or similar. Also have noticed that both engines have a fair bit of end float on the cranks. Is this normal or should I shim them. Thanks for the help so far! 
Andy 

Hello again, I have now stripped the chug o saw down and the list of parts for that I require for that engine is as follows.

carb diaphram x2

pull start assembly 

I starter dog later type 

points

and a coil.  
I have had my second engine running today but it also requires a carb diaphram and a tune up. also could someone with a chug a saw send me the height and diameter of the fuel tank please so I can find something similar!  On another note will I need gaskets/seals if I remove the cylinder to inspect and clean out? thanks in advance!

I've had a look at the serial numbers on my Petro saw, the saw number is lower than @Bodger's saw and my engine is approx #062000 (quite a bit newer than the pump I was referring to the other night).

If it's of a similar age then it probably does use the later A-139-2 starter dogs, measuring the remaining one would confirm this.

 

 

David

I will start to strip mine today and confirm my engine serial number and which starter dog I need! Many thanks for your help so far!

No you need part A-139, which are unobtainable as I found out a few years ago repairing the engine from a Chug-A-Pump, here is the picture I posted then showing the two types.

 

 

I have had to change the flywheel on a few engines to the later type as a result and had to make a new in-between sized flywheel key too.

There is a spare later flywheel here if needed, though it would be easier to use that spare engine he's just bought.

Hi Andy,

 

You've found the remains of a Turbair crop sprayer, it's missing a few parts including the blade guarding, but at least it does have the manual which is often missing.

 

Yes I have new diaphragms & have located a used starter (slightly later) from my spares, I would suggest you go through the engine to make sure nothing else is required.

Also have a look to see which type of check valve gasket is used, if it's not the clear plastic version you might need to change that too, see the carb thread for more information.

 

David

 

P.S. I can't go out at the moment, so will have to rely on someone else to post any parts out to you.

That’s great! I will strip the chainsaw and assess further to see what else is required. I will update once stripped and go from there. Many thanks. Andy

To whom it may concern: I am selling off most of my parts and will still be offering my diaphragms OFF of Ebay. Some of the parts are listed on Ebay, some are not. I have not decided which units that I will be selling, but I have close to 40 and most are mint or restored and many are quite rare. If there is one that you have been looking for, please inquire and I will see what I can do. There won't be many bargains because of their condition and rarity, but I will deal a bit off of Ebay. Eventually they will go up for auction. Thanks, and you can email me at weber.joseph@sbcglobal.net     Joe

Hello there, would I be able to purchase 2 diaphragms off you? Also do you still have any parts available. Thanks. Andy

Thanks!

Yes, from Joe Weber. I will ask him about the other parts.

No you have contact details for joe Webber? Thanks. Andy

I have just bought this today too! So I can swap parts to try the chainsaw but still on the hunt for a pullstart, diaphragms, and ad a chainsaw tank. Thanks andy

Merged the two threads, it isn't necessary to post requests twice.

 

 

I was wondering when that saw would reappear, it was advertised on farcebook.

 

 

 

The starter pawls for the older flywheels are impossible to find, they aren't held in place like the later ones so often go missing, I've had to fit a later flywheel and make a custom sized flywheel key as the sizes are different too.

 

My Chug-A-Saw has a damaged starter too, the early ones are a bit fragile, a later one could be used, but they need modifying to fit the older magneto coil.

 

I would keep an eye out for another engine myself as what's left looks in very poor condition, they do appear in the UK occasionally.

 

David

Hello there. I believe you may have carb diaphragms available. Would I be able to purchase 2 please

Thanks david. I am just trying to get used with using this site! I am confident I can make a new starter pawl, but yes I was thinking it will be easier to find another engine. I am going to clean the carb when I get a chance and fit a wrap around rope pull for now to see if it will fire. it feels to have good compression, just need to see if it will spark. Thanks andy

Yes that is the saw I have bought! It was for sale on a local selling website. Never seen one like it before so had to have it! 

Hello there, have updated my profile. I am uk based where these seem to be impossible to find!

Hello there. I am based in the uk where these items seem impossible to find! I know I am going to need various items but it has good compression. really I need the starter pawl. Pull starter assembly complete, the tank. I will be stripping further in the next few days just wanted to see if the large items were available before I start. thanks 

Hello everyone. I am looking for parts for my ohllson and rice engined chug-a-saw. I need a pull start asswmbly complete or will happily buy another saw, or engine etc. Thanks in advance

Does anyone have any parts for one of these saws, I need a pulstart assembly complete with cover. Thanks. Or I will buy another complete saw if anybody knows of any for sale
