Rules Survey

Bill, if a good strong sport engine is what you want, the OS160 is the  
ticket. With a perry pump and either a Hatori header or a Mueller RTC, and a  
cheapie" Macs pipe, you will have a very good, reliable, pattern type set-up.  
Relatively inexpensive with only about a 4-5 ounce "penalty" compared to the  full 
blown pattern set-ups. As easy to adjust as the MOKI is.

I can  say "yes" to the lack of experince in pattern engines, I am a 
victim of  tweaking too hard. My other engines (OS's  2C's) were a bit 
more  forgiving. I didn't relize it but fell into the "why is it not 
turning up  like so and so's engine.  Not hard to do...heck it was  easy!:>)

I guess a lot of my perceptions are based on "other than"  pattern 
engines and the sucess I have had with them.I had mokis and gas  engines 
and liked them.  My comments are based on the frustrations I  have had 
with the Webra and all the dead sticks I have seen at pattern  meets. A 
deadstick with a $150 sport model vs a 2K pattern ship is a lot  bigger 
deal. I really apreciate you comments and see the picture  better.  Maybe 
the OS 1.60 would be a good  choice........

Bill
