I like my gas powered tools.
I also modify them for more powar!

Usually, I start with the exhaust since home owner trash is usually pretty restrictive.
Once you have that opened up, then you can start adding fuel.
There is always a limit.
First will be of course how much exhaust can exit, then how much fuel the carb can supply...
Then you run into fun things like nitro methane...
I add just a few ounces to a 2 gallon can, then I also up the amount of two stroke mix.
Lots of heat generated, so there is a limit.
then you get to find the sweet spot.
bad thing is, my mix changes slightly every time.
And over time the NM likes to degrade.
RC car fuel with NM won't quite mix right + you add alcohol with that crap.
So, the fun part is to find somewhere to buy pure NM...
Playing with rc cars,
I can get things like tuned exhaust pipes, I have an old one from my RC car that I'm saving so I can adapt it to my leaf blower.
One of these days, I'm planning to play around with porting.
I'll probably start with the RC car, then do it to the leaf blower...
