Don't let the sound of the motor in the vid fool you. It's only idling at around 300RPM, which is incredibly low. Plus, no exhaust that makes it sound like it has a "lobe", which it really doesn't. Lots of fire out the exhaust means exhaust valve probably isn't sealing well along with too much fuel on decel (heavy vacuum situation). On acceleration it probably is running lean given the large carb, and low vac due to the venturi size. That guy is going to find it isn't the motor he thinks it is when he puts it back in.

Garnold, you want to "hop" your engine up: get a LP head, bump the timing up a couple degrees, index the plug and set the high-idle, no load to 3800RPM. The Kerber cam is a good choice (only hear good things about them, but haven't used one yet) but they do cost quite a bit. As much as the engine kit is going to cost, so I don't know how much you are looking to spend. Not really necessary, AFAIC, for the application you are after. Your just like most everyone is....... you want to "hop it up"...... but there is no reason to unless your going to take it to the pulls. If you want more power, put a bigger motor in it. It would be cheaper to do that than custom build a 10hp. Just my It's your money.

This all makes very good sense to me. Yeah, if this is going to cost me a crazy amount of money just to do it I'll pass. My lottery ticket just has not cleared yet so my millions are still held up
