Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

In the true spirit of the Toolman, I am always looking for a way to increase my snow blower horsepower. I came across a company that sells karting engines & supplies. They claim that if I send them my HM100, they can add their hop-up kit and increase the horsepower by 3 to 5 HP, without affecting reliability. I was clear that I'll be using it on a blower not a kart, but I haven't been able to find out exactly what it is they do to the engine. Cost is $135 + shipping one way.
Does this sound reasonable or too good to be true?

Cheers

Yeah. Let us know how it goes. Very interesting stuff.

Clearance of valve to  head------.... You can take it apart and put modeling clay over the valve on the head , bolt it back together and then after pulling through the rope slow a few times, take it apart and mic the Clay's clearance...( to see how much you can shave....

Or you could have the head filled in over the piston a bit...
