    EMAC - Electric ONLY IMAC Events

    Are you thinking of going electric on the 40%er?

    It would be under the lever with the arrow pointing to it that says "Pressing here lets more fuel in reservoir by lifting needle." To get to it, carefully (I.E. put a finger over the lever) remove the screw just to the right.

    Basic engine tuning.

    There's a spring that meters fuel for the motor. Sounds like your spring is too weak and not allowing enough fuel to flow. I had a similar problem with my DA 60. Changed out the spring and it's mostly ran great until here recently. I've decided most of my problem is using pump gas and...

    IMAC The new Dalton 300 SP / 330

    My stepoff is about the same. I'm interested to see how your canopy turns out!

    Fuel flow problem for sure. Check to see that the carb pulse hole (if there is one in the carb block) is lined up properly and then start checking out carb stuff. Can you see about getting a genuine Walbro for that motor? I don't remember if VVRC sells them or not.

    Basic engine tuning.

    Yeah, gas engines are great until they start doing some weird things. That's one reason why I was thinking of going to electric last year. I might still eventually do it for other reasons but it's hard to beat a gasser when it's running right.

    Basic engine tuning.

    Couple of things come to mind but it seems there might be an issue with the GP61. 1) Take the carb to a small engine repair shop that can sonic clean it. Might help, might not. 2) Try changing the timing. There was a similar issue with the DA 60 and that was one of the fixes. 3) I had a...

    Basic engine tuning.

    Richened the high end and got it pretty much tuned in today. I may have to adjust a little bit still but it's really close. When I come down from full throttle, it runs a little faster for 1 or 2 seconds and then comes down to a nice steady idle.

    IMAC First Carden 124" Extra 300 Pro Build

    I go to Tractor Supply or another small farm/ranch supply place and buy needles with syringes. You can also get syringes from pharmacies but I don't know what gauge of needles they carry since humans typically need smaller sizes.

    IMAC The new Dalton 300 SP / 330

    I wonder if offering an ARF of the MEL edition gave Tony some ideas of ways to improve his kits? Not that they're bad to build but some of this new stuff is pretty cool.

    IMAC The new Dalton 300 SP / 330

    Not enough airflow or what caused that?

    Did DA say what could have caused the problem?

    IMAC First Carden 124" Extra 300 Pro Build

    Nice! Have fun with the build and remember that if you have to force yourself, just back away. I started a Dalton 35% 260 years many years ago and then got frustrated and sold the plane. I regretted it and now I have a 39% 300. After 7 years, I'm still working on it because life keeps...

    Pilot RC 107" Extra 330SC

    I took a foamy out in the field next to my house Sunday through Wednesday last week. Good conditions and little wind.

    That and cheaper to replace to boot!

    First Look, ARS 300 From AJ-Aircraft.com!

    I have other projects and I'm seriously thinking about getting one. Now that new 50cc designs are coming out, I'm thinking the 50-70cc area might be my sweet spot.

    Anyone Running 32:1 Redline in a DA?

    Go to O'Rielly's and get a set of the pink ones.

    Basic engine tuning.

    I went back and read the beginning of this thread. I'm going to make the top end richer now too because the engine is also going to a high idle before coming down to a good idle speed too. I was also waiting 30 seconds between run ups because that's what we did when tuning 10 years ago when...

    That's very true.

    Basic engine tuning.

    Interesting. I noticed something similar with both my mower and tiller. I ran fuel stabilizer in the gas and I would always run the engines out of fuel before going into storage. The mower did OK but took a good number of pulls and smoked like crazy on the first start up. The tiller required...
