lol. that's funny. i wish i could think something like that up to post as a joke/hoax. would be too funny reading the replies. lol. this reminded me though of an old timer telling me a story about how when he was coming up the old timers he knew told him about de-carboning a piston head by putting, i can't remember now if it was rice or pop corn, i THINK he said rice, into the engine's intake while the engine was running. funny huh? it would pop the rice on it's way through and in the process clean the intake, cylinder head and exhaust port. lol. i don't know, maybe it was true and for real. i ain't gonna try it though. i'd be like, wouldn't it get stuck in the valves on the way through? would be funny to see a puff of SOMETHING blasting out the exhaust pipe huh? POOF! maybe it would smell like puffed rice.

b.w.

Yes indeed! Highly recommended! The problem probably was that inferior sand was used. Volcanic black blasting grit is very cheap, available at most lumber yards. This port polishing technique is best done at wide open throttle.

Could anyone be that stupid? Sure!

I knew a guy in the 70's that swore the hot setup for a fresh 2 stroke was to fire it up on straight gas and rip a full throttle pass up the street. He said it helped seat the rings.

On the other side of the motorcycle coin, when my dad had his motorcycle shop, he sold a Ducati 450 RT to a fellow used to Maico's. Soon as he got the engine lit off, he'd rev the crap out of it. Dad tried to explain the difference between 2 and 4 strokes, mainly the need to let oil pressure build before really revving the engine. But this guy wouldn't listen. Not too many months later, dad bought the bike back dirt cheap. Engine had about a 1/4" gap at the front of the engine cases. It was a bitch pulling it apart. Not sure, but it appeared the rod let go at the lower end on the compression stroke, piston fired, and drove the rod right down between the flywheels, splitting the cases apart. I've got it welded to a base and can post a link to a pic if anyone wants to see it.

It might be a hoax, but given the low level of technical savvy in people these days, it's possible.

Stupidity, the one thing that is available in truly unlimited quantities...

For this to work properley the engine needs to be run on 90% nitromethane at full throttle.

Best Regards Tom.

A lot of shit talk here fellas..... 90% met ha... good luck in finding the parts. This has to be bullshit.

Yes, they can. When I was younger I worked in production, mold-making, and sales for my dad's company

After a while I realized that there's one of the main symptoms of the differences between men and women is that a woman will happily profess to being mechanically ignorant, while a man will happily demonstrate it to you, on his own equipment.

I have seen friends, customers, co-workers, and customers car builders do things to cars that go well beyond anything that I could imagine doing, both in the 'stupid' and 'clever' directions.

I'm all for it. Not kidding, either!

That, or a muffler that works!

Reminds me of Seagull outboards where I lived in Long Island NY, they had gotten a reputation for poor starting, seems most folks didn't read the instructions. You were supposed to fill the tank then once started run the engine at WOT for a tank full and that ran in the engine, started fine after that. Most just pottered about then put the engine away and wondered why it didn't start well next time. My dad's one was great, started well, ran great, only downside was you needed to keep some spare shear springs incase you accidentally grounded the prop.
