If you want to test if it’s dependant, close the H screw fully while the machine is idling, then gently open the throttle a bit (not fully) and it will bog or die. It may even die at idle just closing the H. If it’s an independent carb, it won’t be affected. It’s not something many know. Don’t...

It’s probably got a dependant carburetor. All the fuel flows through the H drilling before going to the L. In instances like this, you tune the H screw first, then the L. Often the H needs to be about 4 or more turns out.

The cost of bar oil is unreal - it’s literally money slung off the bar and you go through 500mls every half hour… I don’t blame anyone wanting to run used oil through the system, though gear oil i’d pass on due to the sulpher. A replacement oil pump years down the line when it wears is cheaper...

50cc/90cc would be a sweet combo. Grab both a stihl and husky in the shop and see what you prefer. Both will do everything and more. As for m-tronic / auto tune vs adjustable carb - you have an m-tronic 261, you may as well stay with that in your larger saw too. It’s a very reliable and time...

Sorry, auto correct. Scott Bonnar is the brand of cylinder mower I was repairing. The collar bolt is used to pivot the height of the cylinder!

Hey mate :) the guys in the beg for manuals are amazing, no other forum does it as well as these guys! Yeah I can’t get enough of it I’m always making something, the other day I made a scottbonar collar nut! If the lathe ever fails I’ll buy another one I like it so much. Yeah that’s a great...

Threebond sealants are great for saw builds, but their caps ALWAYS split on me after a few times of unscrewing and screwing them on, then the sealant dries up in the tube. Out here in Australia a tube is 38 dollars, so I want to save every drop! This time I decided to make my own cap and fine...

Hey I agree with Dennis, new piston and bearing and move on.

Loctite is the least suitable as it doesn’t take up any imperfection or slight warping. It’s good on perfectly machined surfaces. Motoseal is decent, but lots of people have a problem with it not curing it also has a very short work time Dirko is one of the best, made by Elring, but very...

Make sure the intake manifold is protruding the seat of the partition wall. Over time, they lose their ability to return and thus you get that leak between carb and manifold. This is why it’s essential to use the correct test adapter for the intake and not rubber strips between the carb and...

If it fails because you didn’t pressure and vac test it and then you still don’t pressure and vac test it and just change the seals and now you’ve damaged the piston a second time, you got a ask yourself, would I have been better off buying a pressure and vac tester?

Hey, just a correction, the 462 has spring av, not rubber. Go with whichever you prefer the feel of and has better dealer support near you. Both saws are excellent and will serve you well.

They won’t run at 75-100 psi. The gauge is at fault or not suitable for small engines.

Hey mate, thanks for sharing!

Honestly you’re wasting your money, again, that key is timing, not to hold it in position. The taper is there to hold it. Either way, your saw :)

If the crankshafts were no longer available, on a rare machine and or hugely expensive, it can be done, but to do it properly to guarantee long term success it will need to be sent out, spray welded and then machined back to size and lastly assembled and the crank balanced. Just not worth it in...

Nice, use what works right! The teams at the drags use tomato sauce bottles to spray the super chargers with nitromethane! 22,000 hp flying down the track is pretty crazy to experience.

Hey mate, If it’s a saw I’d put new rings in at 140 and piston swap when it’s around 0.12- 0.14mm skirt to wall clearance that’s when slap becomes audible in these. I had asked Jerry this question a few years ago and found it to be spot on. Every time I heard slap I began to be able to estimate...

Gotcha, yeah there is a small o-ring that sits in front of the button that will eventually start to fail. You can press that button apart and put a new one in. Interesting they didn’t come with caps originally!

Awesome mate, I’ll check the link out!
