Yes, Zenoah 50cc clones! I acquired 2 cylinders of 45mm bore, plus the one on my Alpina saw. Cyilinders have open single port on each side. I measured timing numbers for all of them. Thank you for your tutorial on using that digital angle meter! And now I'm scratching my head what to do with them. Numbers on one cylinder: EX: 105, TX:128, IN:72. Second cylinder: Ex:98, TX;124, IN:80. The one on the saw: EX:112, TX:132, IN:67. The saw doesn't rev high, but it does keep around 8 to 9k rpm in the cut with 18" bar. I don't need a longer bar, but I would like it get to the power a little higher in the rpm range. My first step with this saw will be to swap and try each of those cylinders, and see how the saw cuts with different port numbers.

Ive always wanted to see a video where you test a saw at all the stages of porting so people can see what each step gets for gains. Full Stock, stock + Muff mod; stock + muff mod + base gasket delete; muff mod + base delete + lower transfers opened; then a final test of muff mod + base delete + full port job

I agree.. And I think Joe should do a fully ported cyclinder and test longer vs short blow down...... Start at 25 degrees then 20 and 15 and dyno each step.....

That would be interesting to see just an exhaust mod, run on the dyno. Then add the intake mod and run on the dyno, and then a transfer mod, for a final dyno run to see the differences. Bit of an ask but would be cool to see

I believe there is a lot of interest in the clone saws right now. Yes I know, the China thing. But people are snapping these things up by the handful and upgrading them with Hyway and Meteor top ends. I would love to see a few popular kit saws with baseline runs “as kitted” then runs with upgraded top ends then runs with upgraded top ends ported. With large cc saws running $1500-2200 these kits are popular.

Can you show how to port without having a timing wheel to mark the grinding sections on the cylinder wall? Hopefully it's not impossible and can be done with an acknowledgement of a considerable risk to engine performance but as you say if we're practicing on a cheap asian saw and not a genuine 3120XP the risk is somewhat considerably more acceptable * Good vid 👍
@dynojoemods2764 Жыл бұрын
You really need to know/understand the port time/durations to decide where You are starting and where you want to go. If you know the stroke, rod length you can use some online calculator to determine port height. But a simple degree wheel and wire can be bought cheap. Or pint one off and glue it to a cd.

I understand taking material off the floor of the intake and the roof of the exhaust to change timing numbers. but what about the roof of the intake and floor of the exhaust how do you determine what to grind on them?
@dynojoemods2764 Жыл бұрын
I don't normally mess with those . The exhaust floor dosent really do much at all. And some saws are really close to free port. Meaning the piston dosent seal off the exhaust port and the charge from the case can go right out. Intake roof adds more time area, but it can make a saw slow to respond. Or lazy.

Hello from Brazil my friend Can you try to help me, please? My chainsaw(chinese) has a problem with excessive compression. But when I remove the spark plug the piston rotates normally. Even placing your finger in thze spark plug opening causes the piston to become extremely compressed again. Yesterday I installed a completely new cylinder and piston, but the problem remains. I changed the spark plug, removed the carburetor and exhaust fan, and still the problem remains. Do you have any idea what it could be? Can I send you a video showing the problem? I have been seeking help with this mystery on various social media channels, Instagram, KZbin, but no one has been able to guess what could be causing the problem.

Depending on bar size 10t may be a bit much. But short bar that could work, 8-10* seems like a lot of advance. It may want to kick back a bit and could even detonate.

Why texture on the intake? And how do you know where to mark it to know how far to cut?
@RyanMcIntyreАй бұрын
Texturing the intake promotes turbulence and prevents fuel from dropping out of suspension. I can’t speak for Joe but I know where to cut based on cylinder timing (height of port) and time/area (width). Each porter has his own opinions and ways of going about the same task and different results, that’s what makes it an art. Remember in the beginning when he said to round the top of the exhaust port to avoid snagging the ring, but flatter ports make more power? That’s up to the individual how round to shape it, based on experience, trail and error, and personal style.
