OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Chainsaws and Concrete Cutters Petrol Chainsaws and Concrete Cutters Concrete saw

Bloke dropped off a concrete saw this morning with a broken pull cord. Why do pull cords break, because dickheads keep pulling them till they break because the motor won't start. I checked the fuel and it looks straight petrol to me but the bloke assures me the fuel was mixed. I asked him what oil he had used and I got a vague answer stuff for a lawn mower. Now unless there is a mower 2 stroke oil that I don't know of that is the same colour as petrol. Is there such a thing . I can't try to drill start it because I busted my reverse drill recently starting a chain saw. Does anybody know of a decent forward/ reverse drill that is not stupid money? Not worth my while buying an expensive drill for the odd times I use it trying to start a chainsaw/demo type saws

You can do the saucepan test boil the fuel and see if oil is left over or even pour it on some cardboard and wait 20 minutes. As a control, pour straight fuel on the same type of cardboard and look at the difference if any after about 20 minutes.
I personally would just pour it into a jar. A lack of any tinting will give the jig away.

I'd have thought any corded power drill will turn a small motor over.

MF,
I broke the gears in an old 1/2 inch Sher drill, and I have broken the shafts on 2 of the 3/8th forward/reverse drills. I'm going to need at least a 1/2 inch drill

Hi Norm and Mf.

If I went to a market or tip shop I would go for a corded drill, 1/2 inch chuck around 700 watt min in aeg metabo bosch dewalt makita .

A cheap new drill is a 500 watt Black and Decker https://www.amazon.com.au/Black-Dec...d+decker+corded+drill&qid=1669445868

At $56., 500 watt ,but may not be enough watts for starting mowers as I use a 800 watt drill.

The other cheap new drill 750 watt https://www.mitre10.com.au/stanley-fatmax-drill-hammer-750w

Yes Max, that is what I am looking for a corded forward/reverse drill

Try Cashconverters..... or other local pawn shops , some good deals. Norm,
speedy

Norm, a reliable cheap drill now days is an ozito with a 3 year warranty - costs you $20 a year to own a drill. when it carks it take it back and swap it over.

If you want to be really clever, ask for a refund toward end of 3 years. Bunnings screw us hard enough on everything else.

The crappiest 2 stroke oil on the market (shell 2T in a yellow 200ml bottle) doesn't show up in petrol. Also has bugger all lubricating capability

I sure hope that oil is not around here.

I always assume straight gas when no dye present other the normal fuel grade dyes here.

But I have also recently gotten myself an endoscope for looking inside the cylinders. This saves a lot disassembly work just to verify straight gassing.

Hi AVB, The only reason I know about it is a guy told me he used it and his trimmer wouldn't start. worst carbon wiskering i have seen in a while. He showed me the oil and it just looked like regular 15w40 - didn't dye the fuel at all

I picked up a endoscope as well earlier this yearhave had similar good luck with it

Ok so I did the test MF described on a piece of cardboard, straight petrol, his fuel and 25:1 mix. After an hour could not see the petrol, his fuel left a slight stain and the 25:1 left a decent stain so I'm figuring he may have added oil but maybe at about 50:1 I should have got an endoscope years ago, just never got around to it.
speedy, good call I hadn't thought about Cash Converters
Tyler, you always have an angle on everything, things I would never have thought about
AVB, there is always something out there to trip you up but I think the fuel on the cardboard trick must be fairly accurate

Hi all,

I'd be spending a fair amount on a decent new drill or buying a decent drill second hand , if you ask anyone working at Bunnings about buying ozito they tell you it's only good if you don't use it very much.

I've never seen any Ozito electric tool last if used continually for a few hard hours.The only time the cheap electric tools lasts for me is if I buy
something that is say 1500 watt but I only need 700 watt , so it only gets used to around half it's capacity .

When looking at the Reviews on Bunnings for the cheaper drills , a lot say the drills failed straight away and even the next replacement drill.

I've repaired aeg metabo bosch dewalt makita drills and they have lasted decades.

Cheers
Max.

I bought a 1400 watt GMC drill a little over a decade ago as a spare but can't remember paying $35. at the shop ,it
may have been $20. just remember the shop clearing out a lot of drills at the time.

I haven't thought about testing for oil myself here. Most around here packs meant for 1 gallon containers. There is always someone that try going el cheapo that get them in trouble because they don't measure accurately.

As the endoscope it took me a while to find one that would fit in those 10mm spark holes. Very few I look at would even come close. I am however disappoint that they went the cheap route for the right angle mirror. It was a piece plastic with foil backing and it didn't even work so checking those cylinder is not easy as it should be.

I bought an endoscope at Aldi years ago only to find others used a much thinner end than mine.
Many years later Aldi offered one with a much thinner end for a similar price!
