<DIV>This engine sounds so strong, it though it must be a 140DZ.</DIV>

<DIV><BR></DIV>I really hate to do this to myself but I think that I owe it to all the people that offered an opinion to me about my engine. The engine has been idling at 2150-2200 all along. The tach that I was using was taking a really long time to settle down. It had been a while since I had used it. I had a friend help me at the field before I went drilling hole and what not. When he put the tach on the engine he waited a little bit longer than I was apparently and the engine or actually the display on the tach dropped right into line. Come to find out the battery in the tach was very very low. I replaced it and now the tach reads pretty quick. So I guess all that to say I am a big DUMMY.<BR><BR>I thought that I would share this as a little humor. Again thanks to all that gave there input.<BR><BR>See you all at the next contest.<BR><BR>Dan<BR><BR>John Ferrell wrote:

<DIV><FONT face=Arial color=#000000 size=2>That is the first time I have heard of that much prop on a Sport 140. It is way too much prop for break in of a new engine. I don't know if there is any damage due to that load. I use about 40 ounces of fuel on tat engine to break it in with a 15-10 prop at about 8200 rpm. </FONT></DIV>

<DIV><FONT face=Arial color=#000000 size=2>I feel the bigger prop will generate more heat and will need more latitude for mixture control than the YS system provides.

There is more oxygen available in the higher nitro fuel so you have a wider needle available.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>BTW, what is the max rpm you get out of a 17-10 with 20% fuel?</FONT></DIV>

<DIV><BR></DIV>The engine is a sport. It has less than 40oz through it. I am running the 1.40, NHP 5/8th header and ES carbon 5/8th inlet pipe. Sorry I forgot to add this on the original post.<BR><BR>Bob Kane wrote:
