RE: Upgrade Volcano S30 Engine
I'd really enjoy the challenge of reworking the truck to use a larger, slide-carb engine, but Ireally don't want to be trashing dogbones, drive cups, and all manner of gears every timeIgo to drive.
On an unrelated note, I've also had some problems tuning the engine. Its properly broken in, and runs ok, and starts ok. If Istart it at neutral throttle (no gas, no breaks) the engine starts and will idle ~20 sec. But if Itry to accellerate, the engine will quit.. If Istart it at >50% throttle, it runs fine, drives fine, and I'll go and hit the breaks and spin around, and then power out of the spin no problem. So if the engine runs at high rpms, then Ilet off the throttle and hit it again, it goes fine. But if Istart it, and then try to accelerate, the engine quits. Ican't figure out what the difference is. The HSNseems good; at high throttle it sounds like other Volcano S30s that alishanmao character drives on his youtube vids, goes fairly quick, and still makes some smoke under accelleration. When trying to launch from a stand-still, however, the engine rpms suddenly decrease, and then it revs up and goes, but it takes a second to start moving.
The engine quitting when Itry to accellerate from idle makes me think it would be too lean, but then Ipinch the fuel line close to the carb, and it takes well over 10 seconds to die, increasing rpm slightly over that time, which makes me think too rich. Idon't really know where to go from here...
EDIT: Would the fact it is 20 degrees farenheit have anything to do with me being unable to tune it properly? I've always had the problem with it taking a second to start moving, but the whole thing with the engine quitting is new since Istarted running in snow.
