looking for a new engine, dont give me that os 18 tz crud, its too overpowerd for my taste, looking for a small & tough .12, .15? engine. i was thinking i should buy the stock t -15 again?

sh12 pro,the orange head version. cheap as chips and fast as **^%

cool cool looks cool , but does the pull start fit?any others i should look into?

Can you guys post a link to the sh .12 your talking about? Is there a side exhaust option? Thanks, Joe
