tuning

I have a Stihl 024 that I’m working on, and I’m scratching my head on tuning it. The carburetor has a new rebuild kit, and I believe the metering lever is the correct height. The initial settings are one turn out on low and high, but it wants to run at 3/4 turn out on the low side. When I turn...

Hello, Here is question to ponder on your Sunday evening... What is the proper way to tune 2-stroke engines that are always loaded? For these engines I am thinking mostly blowers or line trimmers. Due to the loading you can't get to the traditional 4-stroking at WOT and can't really judge...

I put away a Makita EA4300, I had the muffler gutted. I cut an hour with it in a log pile, Two months ago, I cleaned it up and was in the process of running it dry, I noted what looked like a spray of fuel coming from the exhaust as I cycled it, I let it idle until I heard it die a little...

Hey fellas, I opened up my new 445e muffler a little bit (drilled Two 1/4 inch holes and removed spark arrestor) I have the tool to adjust the carb. I believe I have it four stroking and it cleans up well in the cut. After a few hard hours the plug looks pretty lean, if I back the H screw out...

Hey everyone I'm new here. I have a husqy 435 that I have almost decided to set on fire. I never could get it running right. It had odd intermittent starting issues usually when hot, then all together. I tried all the usual suspects. Put a new carb on, new vent filter, new fuel filter, new spark...

Looking for suggestions on a new tuning tach for small engines. I have a cheapo one, but I know the readout is not very fast, and perhaps a tad low. I have several upcoming projects, and I don't foresee the projects stopping anytime soon, so I've been looking at the new stihl ED9, but does...

I have a Stihl 029 Super that I bought new approximately 15 years ago. I have cut A LOT of wood with this saw. I've never cut the saw any slack. I've been threatening to do a muffler mod on it for a few years now and today I finally got around to doing it. I removed the limiters on the carb so...

So I bought a new 390xp last week, and I've been trying to figure the carb out. I have always tuned in wood, getting it to cut clean and 4 stroking when the load is lifted. I can't seem to get my 390 to 4 stroke though. I set it at the richest the cap would allow and worked my way up to the...

I have read that you don't want to run a brand new saw wide open out of the wood, but at the same time you want to check the RPM's wide open with the Tach. Do people tune these saws with the chain in the wood and under load, or do they open them up without a load on the chain and check the...

Hello All! I have been lurking on this site for over a year now and have never had a problem that was not already addressed elsewhere, but I do now! I have a Stihl 084 that I'm working on for a customer that has me completely stumped. It is currently firing and running a few seconds and...

I have read a couple of older tabs on tuning the sweetheart Dolmar that I own, and it seems that there have been issues with not being able to get them to clearly 4 stroke. I don't own a tach, although trying to tune this saw is making me wonder if I need to break down and get one. I last ran...

See video please. Is my saw tuned okay? I recently took the limiter caps off my echo cs-600p. Can't tell if this is a lean saw, or a tuned one. Brad
