I have wondered the same thing myself. If the porting and pipe was geared to work right around the limiter if it would be nutty or slow or what.I have a question. How would an electric carburator respond if you put on a pipe, expensioncamber to the engine? Best Regards Bjorn
Just get someone to swap a pipe from a 66 to a 661. That should give you some feedback.When you do a simple Muffler mod the carburator Will correct the fuel curv. so I think it would do the same With a pipe. But a pipe is alot of work to make and calculation so i want to be sure before I build one.
But the Guzoutta hole is directly related to the Guzintta hole....and that "matter" guy says no "matter" what you cant make matterHmmmm a pipe saws porting is way different to a muffler saw ......
