RE: Blue head Hanno
after getting this engine , i changed the bearings .then i ran the engine to see if the carb and pump were ok.the only prop i used was a 13x8 apc. it turned 11300. i should have tried props to load the engine down in the 9700 to 10200 RPM range.i will have to do this in the future as i am pretty confident my wife will win the bid, even if it costs me the f,in fees.

roguedog if you shave the head down 2 mm you change the squiss band of the comustion chamber. this could cause pre-detonation and a host of other problems. and as far as your article i glanced at it and got the jest of it.and with out using the shorter fsr rod u would have to use a end mill to make the head less than flush to the top of the liner.because with the longer hanno rod the piston comes flush to the top of the sleeve. hence shaving the head along does not work. and i have measured the ID of the sleeve and it is in dead 24 mm.locking at the sleeve how ever it does remind me of say rossi or picco. but if you look at the picture of the top of the sleeve yousee that there is an accurate key way to guide and hold the cylinder and ports in proper alignment.has rossi copied OS in it,s manufacture of engines.anyways roguedog have you ever even eaten in canada.

RE: Blue head Hanno
sorry i thought you where talking about the vf conversion. the hanno is the 24 mm stroke crank and hanno stock rod and 24 mm piston which certainly seems to have been specially made for this engine. I will post an engine test in the next couple of weeks weather permitting.this is a cold winter , have seen -47 with out the wind chill.i have quite a few 13 13.5 14.4 APC props to test.so you guys have a good one.

RE: Blue head Hanno
and the reason i decided not to sell the engine was because you guys where basically accusing me of trying to sell an abortion. So as not to take a chance in pissing one of you guys off with having this blue headed none stainless bearinged beast in your hands. I did not have my wife bid to up the sale price. Do you think some one was going to bid more than 500$ for it. THe best part of this experience is i am now using two fingers to type. If any of you guys go to toledo in april i will bring the engine for you to look at.

RE: Blue head Hanno
and once again ROGUEDOG is how shall i say, more right than me.i was at my shop and took the rf with the rfn piston fsr sleeve apart. i took out the 1/16 inch of shim i had under the lip of the sleeve. know the ports do line up perfect. the piston is still below the exhaust port at BDC BY SAY 30 TO 45 THOU. I LOOKED HI AND LOW AND FOUND 5 24 MM. HEAD GASKETS. AND THIS ALLOWS FOR THE PISTON NOT TO HIT THE HEAD.BUT I AM SURE I AM GOING TO HAVE PROBLEMS WITH TO MUCH COMPRESSION .I WILL HAVE TO PLAY WITH ADDITIONAL HEAD GASKETS I AM SURE. TO CURE THE EXHAUST PORT LIP PROBLEM I THINK MAYBE I WILL ANGLE THE LIP DOWN INSTEAD OF LOWERING THE PORT THE TOTAL 30 TO 45 THOU. OR MAYBE I AM WORRIED ABOUT NOTHING. WHAT DO U THINK

RE: Blue head Hanno
EH AND IF THE HANNO OR RF (LONGER ROD) IS USED IN THIS CONVERSION THE PISTON SITS ABOVE THE EXHAUST PORT BY 1/16 OF AN INCH. MAYBE THERE IS A ROD I DO NOT KNOW OF THAT WILL SAVE ME A LOT OF FILING.

dear scott, i told here to bid 350 so she did . then i thought to be sure i would retain the engine i told her to raise the bid to 500. she was never out bid and the time line was 30 seconds between. u see if i had planned to up the bid this way do u think i would have told you that i was doing it. and especially when i said i was going to keep the engine this way .even if i had to pay fees to ebay. go back and read more carefully before u make accusations .

RE: Blue head Hanno
I would think that if the piston is going below the exhaust port it would provide a better intake charge. I do know that if the top of the exhaust port is lowered it will give you higher compression, which could lead to pre-ignition, if using high content nitro. In the Hanno article Clarence talked about how they raised the exhaust port .027 in thereby lowering the compression. From what I could observe from your pictures of the blue head there seemed to be carbon build up in the combustion area which is a good thing e.g. no pre-ignition.
I don't think it's nessesarily a problem usless the compression was raised then the issue with high compression, high nitro content causing pre-ignition to occur. As an general example if your using a blower or turbo to force an air-fuel charge into an engine, normally you lower the compression ratio to avoid pre-ignition. Using a naturally aspirated engine (carb only) you can use pop-up pistons but only with a higher octane fuel.
