I've been seeing this pop up on my YouTube feed all the time. I was ignoring it figuring it was click bait. I'm pleasantly surprised. I'm interested in the mpg.
and quite smart, many of his other videos are worth a watch if you haven't alreadySame man. This dude's crafty
I watched about a minute of it and had to stop. He thinks it's "dialed in" and it's got a 1/2 second hesitation when he spikes the throttle. The fan shroud is missing and overall it looks like a rolling demo of poor workmanship. The chain holding the engine down is similar to Chevy's fix in the mid 60's for their break-prone engine mounts that pinned the throttle wide open so I'll let that go. I ran a 302 with a 490 cfm Holley and then swapped on a 600, power, throttle response, and mileage all improved. Too small a carb doesn't mean better mileage, it means restricted power. 14.7:1 is the important equation.
This is what impresses me the most. What us common folk are capable of doing these days. It's insane like imagine what the cost would be for something like this 40 years ago.However it’s pretty impressive what he does to get it to run so well for such a restricted carb. He basically makes his own ecu with a second throttle body parallel to the one hooked up to the actual throttle. He uses this to maintain the correct a/f ratio.
sooo,, what's the difference between a normal carb at part throttle and a lawn mower carb at full throttle????
seems to me what he has is half of a quadrajet.
