It's a small one, Hard to start..... someone gave it up............ Cleaned the carb, faint spark. Got it going........ Then read the instruction sticker, prime 10 times , I was only priming 6.......... Prime 10 with full choke and it starts with no throttle...... It has done a few jobs, but needs a kit , maybe the exhaust cleaning out... it just stopped a few times during a job, got it finished.......
The drought is full on up here. I mowed the weeds and trimmed the edges.......

Talons have a bad rep, but they are actually pretty good. I've ended up with 4 of them - all full cranks though. Once you work out how to adjust the mixture on the carby properly (bit of a pain with this type of rotating barrel throttle valve) they run well - I can post carby adjustment procedure if necessary. I had a hell of a time with the 1st one, then the rest were fine.
The coils are a bit hit and miss - one I have found sat very crooked and caused bad spark - needed 1 small washer to level.
I am currently experimenting with soaking the carby gaskets in armour-all - like victa primer bulbs. 5 day soak, it works fine (ryobi with walbro) - dont know how long it will go before it goes bad again, or if armour-all has perished the gasket. I only do the fuel pump membrane, as this is the only problem 99% of the time.
If its got the original Jenn Feng spark plug, thats probably the issue. They are really hit and miss
Don't you mean the metering diaphragm. Most fuel pump diaphragms are mylar with a few that are still rubber. There big different between a metering and fuel pump. The metering diaphragm main purpose is to open metering lever to open metering needle where the fuel pump diaphragm main purpose is to pump fuel pass the metering needle into the metering chamber.
Anyways it best to replace the metering diaphragms when harden.
Metering diaphragm always reminds me of a mini tape recorder reel. That was one of the most helpful posts on small carburetors I have read AVB. Good grief, those starting instructions on the Talon are reminiscent of the instructions for the zero gravity toilet William Sylvester is reading in 2001 A Space Oddysey!! With my old 31cc Ryobi without a primer, it's full choke, pull with throttle fully squeezed until it pops (usually within three pulls), move to partial choke and it fires right away, then move to run and you're off.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
Yes AVB, that's exactly the bit I meant - I couldnt think what the metering diaphragm was called.
I just want to see if armour-all rejuvenated them - 9/10 times the reason people get rid of these is perished fuel lines, clogged fuel filter and carby, 'non adjustable' mixture screws causing cut out, bad spark plug or broken pull start due to a combination of these. Sometimes a coil, or cracked fuel tank.
Straight fueling is, as you would know, leading cause. That's why I don't buy anything with a pull start that doesn't at least partially work (springs slip and lose tension).
Out of the 30 odd small 2 strokes I have bought from tip shops, I can honestly say I have had 3 with bad metering diaphragms. A 93 Ryobi, 95 Ryobi (due to age), 2012 Homelite. The homelite was from a tip shop where all the petrol stations in the surrounding suburbs have E10 - maybe coincidence, maybe not. In WA, many stations don't have it yet.
As a side note, I was reading the Homelite line trimmer manual on the Bunnings website - it says use minimum 91 octane petrol [R+M]/2. So doesn't that mean 91 AKI, 96-97 RON in Aus?
Thanks Tyler and for the info AVB. I will pull it apart today and order a carb kit. They are so cheap... I found this review of the machine.......... https://www.productreview.com.au/p/talon-25cc-curved-shaft.html That's a bit harsh. My friend gave me his old line trimmer, it had bent sharft, That was when it hit the wall.......... Not Talon tough.
cheers speedy

E10 is everywhere here. Most common used fuel around here is the 89 octane petrol [R+M]/2 and I have seen no problem using it. It not as much the Ethanol that but is all the additives in the fuels around here. Plastic lines (Tygon) just don't like fuels. I do replace a lot of metering diaphragms here so much that I stock them for the Walbro and Zama carburetors so I don't break carburetor kit just for one. One of the things I finding on some trimmers and chainsaws is that the metering levers are not set correctly from the factory which is causing problems. Walbro now has two different W metering lever setting tools as the newer carbs have different settings. So far Zama is still using the Z tool for all their carburetors.
Also a lot of the clones look to use the same metering diaphragms as the Walbro and Zama. Be careful they are not all using the same design as the Walbro and Zama carburetors.
The carb is a Ruixing , copy of Walbro WYL. So I ordered a kit. https://www.ebay.com.au/itm/Carburetor-Repair-Fuel-line-Kit-Fit-For-25cc-33cc-Brushcutter-Talon-Trimmer/282777074530?epid=4011588712&hash=item41d6d3bb62:g:kgQAAOSwvTpaN60X

I put the three main gaskets/diaphrams in and a mini O ring. Had a few leftovers from the kit.... It started easily and runs well............. I'm happy with that. Pity my favourite Makita 4 stroke job didn't go so well. cheers speedy Bundaberg Had a rain storm here yesterday which broke the drought, and from brown lawn, you can see green shoots everywhere

My main complaint with e10 in my car is the fuel economy is impacted more than any saving over regular petrol. With the Victa two stroke, it melted the polycarbonate spike attached to the fuel cap which sticks down into three fuel to act like a fuel level indicator and it melted onto the fuel outlet to the carburettor, blocking the supply. The one good thing it did was stop the engine ping with the 3800 V6 in my 1995 Toyota Lexcen (a re-badged Australian Holden Commodore sedan), even though I mainly used LPG as it had a dual fuel set up. The engine was based on the Buick 3800 V6 and set up for rear drive.
