Horatio 3rd updates on STS 30M
Well, I’ve run about 7 tanks of fuel through the D.30 now. I’m leaning the needles to a point where I can blast the Savage around, but the throttling is still rough at this stage with the needles set rich. The engine runs cool on the 25% O’Donnell fuel. The pullstart has been very reliable and the engine starts very easily. I’m not a fan of pullstarts and I will ‘upgrade’ to a roto backplate in due course, but the pullstart is pretty rugged thus far.
The engine was nice and tight when I got it, but not so tight as typical competition engines. The engine is eager to start and stays running even while warming up. The piston never once got stuck at TDC, even during the first couple of tanks.
The Power delivery of the D .30 is very agressive to say the least and even with the needles set rich, the engine hauls the Savage around very rapidly on 18/49 gearing. And it’s very loud on the Ribbed exhaust. As in ‘very’. The engine is showing early promise and it’s going to be a screamer, without a doubt. Cue dremmel, stage right……
The Fioroni Turbo Slider is working, but the shoes are slipping slightly. It may need some bedding in, but so far the clutch doesn’t have enough ‘grab’ to lift the front wheels. Unlike my stock 3 shoe clutch
I have a small piece of silicon fuel tubing slipped over the TVP on the right side to protect the edge of the STS engine and the header pipe. It works a treat. It’s something I’ve always done with my Savage.
While I’m running the D .30 rich, I will say it consumes fuel at an almost alarming rate……roll on the time when I can set the needles to optimum settings.
More updates to follow….
