Piper Chuck, Montague, Ophose,

Thanks for your very fruitful replies. I never had engine problem, until I had this engine HB .61 which is not PDP, that engine gave me such hard time, my friend senior flyer even gave up on it, so he gave me K&B's old engine which is also .61 and a fuel pump at the rear right after back plate. I don't use that fuel pump. HB engine is the one I wanna disassemble it and see what exactly the problem is and then I would probably drop car engine oil into it in order to get rid of grits sands etc. I have seen an engine how it looks from inside, and how piston moves up and down, and turns the crankshaft. I also had Evolution's .45 engine came with P51 Mustang PTS, it flew my plane good for more than a year, after that engine started gave me trouble and as I dont have any 40 size plane mustang crashed[&o] so point of using it. I also wanted to open it too why it started giving me hard time.

Now as far as K&B engine is concerned that is my friend's engine, and naturally he gave it to me to use it and as Im entrusted to that engine, I cannot disassemble it, I can only do it to my engine, which I left it at my friend's house which I can get it anytime. Thatswhy I wanted to disassemble my HB german engine to look into it and unearth what really is the problem. For the last 6 years I have been in severe financial crisis, but I have not given up my hobby, now condition is this that I cannot buy a new engine of $100 which I prefer ASP or Magnum. But I have offers from bank and from an insurance company prolly I'd join insurance company as they are expected to pay more. Anyway, thats not the topic, infact Im desperately waiting for my immigrant visa which has been stuck under the security check for the last 8 months and this 18th its gonna be 9 months. I wanna continue my hobby in USA, I wanna do a good job in general insurance company, do my MBA and another Master as this is a beautiful hobby, and I would continue doing it and ofcourse USA is the LAND OF OPPORTUNITIES and have more stuff of RC available than Pakistan. Anyway, I'd take your advices, I won't disassemble the engine, but I would certainly give it to my friend who had been doin this job pretty well.

Thanks again for your input

Happy Flying [8D]
