Title: PA 51 Series 1
Post by: Walter Johnson on February 02, 2007, 06:39:47 PM

     I have a PA 51 bought during March 1996 is this a series 1 engine. If so are there any mods needed to improve the run. The engine is new broken in excellent condition on the crankcase the #190 is scribed and pipe on mounting lug. It was bought with a carbon pipe from Randy but the sales slip does not say the model of the pipe.Thanks Walter

HI Walter,

Sonds like about the same vintage as my .51.  Haven't changed mine any, and Randy has never said much about doing any changes to it.  I hope he jumps in here!

Hi Walter

Being that old it is most likley a series1  Nothing at all wrong with them, they run very well. when and if,  you wear it  out it can be updated.
I have a combination series 1\2 PA 51 in my KATANA that I have flown for several years now.
best thing is to fly and enjoy

Regards
Randy

Thanks

Hi Walter  , Bill

Walter the  new pipes are 1/10 inch  larger diameter than the older pipes and  are  better pipes, so make sure not to make the fuse and thinner than shows on the plan. Also remeber to keep the  header  the  full  lenght, and  trim the  pipe only, it will last much longer this way.

Bill the  main differance in the series 1 vs. 2 are   the  crankshaft and  head was changed , the case and venturies  also went thru a tweek at that time  too. All the  parts are interchangable  so  any  wanted  updates can be  done.

Regards
Randy
