Just looks like the puller having a coarse thread will give you less mechanical advantage Speedy.
The one I just used had a much finer thread and with the 12 inch shifter the flywheel popped off , I usually drill and tap the holes all the way through but this one was not right through ,didn't even use WD40 ,the steel centered morse tapers I will discard and replace the flywheel with the alloy centered one .
The GCV 160 coil should fit well on these engines.
I'd go back to the car balancer remover tool Speedy and just hold the remover tool with vice grips and then tighten the bolt as much as you can or just use a rattle gun on the car balancer remover puller bolt.
I haven't broken one of these alloy taperd flywheels yet this way, but when pulling the flywheel from the outer edges they can break.
The one I removed took a fair amount of effort on the 12 inch shifter when tightening the puller bolt ,they always take a fair amount of force to remove the flywheel from a taper.
Must be like some of those old Southern Cross flywheels. They can stick there like they are welded. It will come free eventually and when it does it will let you know, although some come off more with a whimper than a bang.
thanks FG, been doing that.... today I held flywheel in fingers as mate hit nut on sharf with a few blows....... it's gotta go soon. There's a cam sleeve inside and a square pin that lockes all together, and some rust that has welded it........ soaking with WD49 heat . knocks speedy

I guess it probably doesn’t get that cold in Bundaberg but if you try it first thing in the morning when it’s coolest, freeze the extractor bolt in your deep freeze beforehand and use the heat gun on the flywheel that’d improve your chances of freeing it up.
They do get rusted on occasionally. I used to muck about with old cars a fair bit and found there was a crc penetrant product that worked a lot better than WD40. I can’t remember the specific label but I’d give rusty bolts and such a squirt every day for a few days and then found I had many fewer threads to rework and stud extractor kits were less frequently required.
The risky approach is to use an impact gun as that delivers shocks as it winds, risky because I’ve seen them pull the centre out.

The flywheel with the steel centre, tapered insert can easily get stuck tight to the crankshaft but even when the alloy flywheel centre is corroded I've still never had one break .
I usually replace all the steel tapered centre flywheels with the alloy ones as they are much easier to remove and this is what Villiers also did on their engines so the problem must have been well known.
At least in our climate I think more advanced corrosion tends to happen when the mower has been allowed to get wet either through being left in weather or inappropriate washing particularly in seaside conditions. In any case, it seems that the more exposed damaged mowers have the steel “cast in” sleeve bond to the shaft when there’s been a solution to promote corrosion.
I had a ‘75 Victa I rescued from a beachside place where the centre tore out. That machine was perhaps the most corroded alloy-based Victa I’ve come across.
For what is worth the straight finned flywheel takes noticeably more power to spin than the curved one. It also pushes a lot more air. We noticed this when racing Kirby KAV87's etc. on karts, they used the same flywheels. For racing we preferred the steel centred ones as they were more durable when being "punished"
Love the Pope, keep up the good work!

4 weeks , sprayed WD40 penetrant. Setup ford puller, heat, bit of pressure on the centre screw................ one almighty crack and it came apart, I wasn't even touching it. Points were set to 48 th", so faced them with sandpaper and set to 20th". nice big blue spark..... not bad for about 57 years old Cleaned them up, put flywheel on, head on and cleaned carb, made a gasket..... I'd like to decoke rings and grooves, but they look clean. don't want to risk breaking a ring, but it looks like Victa 125cc rings would fit. A victa piston fits, but could not use because of the domed top.
I put one of those starter cups on, so I could start it with a rope......You don't have and springs to bugger up....... ha ha speedy

I just want to see if the motor runs, so I put it on a Victa base.Doubled the spacers. Had to drill one hole. It has four bolts. I wonder if those spacers and 4 bolts will be strong enough. It's a 125cc engine.
I have to make a muffler. I'll try to fit a B&S one I have. Do you think it would start without a muffler..... maybe a long pipe just to test it....... speedy
........................Keep your blades sharp......................
I got the B&S mufler welded and the Victa disk welded to the Pope flat boss. test run today. It kicked over and ran well. Let it warm up as probably had not for 20 years.... It blew some smoke. and the Zenith carb worked. The butterfly changed the revs like it should. I messed up the camera so only got a short video.
I noticed the fuel line disconnected, and the disk nut loosened.... Fixed those and try again. I ran but something is wrong. I think carburation, spark and maybe exhaust backpressure........
I can check points, put Victa carb on, and put a tin can over mufffler to make more pressure..... Anyway here's the test run https://youtube.com/shorts/DVn8ioLeKYU

Tightened the blade disk, and took flywheel off to test spark......... spark plug nearly fell out.... stupid...... It ran ok, but a bit rough. I suspect the 4 stroke muffler is giving the wrong pressure to the engine...... Don't know much about that, but i know 2 stroke motorbikes can be really affected by the muffler.......

Test 6 with Victa LM carb...... Nothing else would fit. Still a problem, throttle movement didn't affect revs... Just wanted to see if it would work....... I want to get the Zenith going.......
cheers speedy
