Thanks Jeff, I do appreciate any input, and your advise is sound. Here is a video I took before I tore it down. By the time I decided to take a video its performance had been increasingly getting worse. I found two hammered valves, both intake and both of them were on one side of the engine and...

George, the valve itself has been hammered smaller. The valve got quite thin during machining, and was delicate to begin with. The other valves are a bit thicker on the big end and subsequently stronger. The valve seat on the worn out valve is in good shape still, I will need to make a light...

Well, I may have found a problem. I was adjusting the valves, and noticed that one of them was not adjusting, it just kept getting deeper and deeper in the valve seat. Upon removal of the head I noticed that valve's seat was completely gone, and the valve was getting close to going past the...

Well Done Chuck! She really sounds great, and powerful too. Kel

They got it all wrong. Nissan should be making those incredibly awesome gas engine powered devices, they might make more money, and thats what it is all about anyway. Lets face it, these companies could give a damn about the environment, and if making "Green" cars is profitable, than they...

Well, with all the great information, I have managed to make the spark plugs more reliable by increasing the gap. There is another bug which I cant get figured out. Ever since installing the cooling system the engine can take quite awhile to start. It requires the assistance of the dremel until...

I am using R/C fuel tubing with heat shrink tubing over that on my TI4. It makes a nice looking boot, however the boot ends up much larger than the wire, due to the thick walled tubing, but it does hold nice and tight to the 1/8" brass plug contact. Is the cap you are talking about made of...

I really like your method with the spark plug wires. :bow: Very Clean and neat looking. What are you using for the plug end? Kel

Hello All. I am still working the bugs out. I made a new camshaft with a 260 duration on both, the original was 220. This made the engine breath better and decreased the compression ratio. I also made a dished spot in the top of the piston to accommodate the slightly longer spark plugs. This...

Thank you all once again for your kind words, and positive comments. It really means a lot and makes it all worth it, and to get POM is a great honor, and the icing on the cake. Kel

Thank you all very much and thanks to all who make HMEM possible. This is a great honor and I am overwhelmed with joy. It sure is a great feeling seeing ones engine on the top of the page. This engine is a direct result of the great community on HMEM. I would never have contemplated this...

Thanks Guys, it really makes sense now. It seems that my preventative measure is what caused the problem. I have bearing bronze bushings now, which I have had good luck with on the mains and cam. Perhaps I should get me some of the 7075. It sounds like the cats pajamas. Kel

Upon tear-down and inspection of the TI4, I noticed something strange. Once I took off the oil pan I felt the slop on the connecting rods. With the pistons at TDC and BDC there was some slop, but in the oposing direction there was none. This would indicate that the connecting rod journals have...

Great Job CS!! Very nicely done, and it sounds great! Kel

Troy, congrats on the purchase. It is a great saw, if you have a use for it. I purchased mine as a means of cutting certain siding products for work, I quickly realized, as did you, that it is hardly a finish cut, and when cutting metal those little lubrication sticks that come with it are a...

I get my small screws from Enco. They are sold in packs of a hundred for $5-$10. Watch out though, the five to ten dollar packs are of the more common sizes (lengths not thread size), , if you choose something funny like 7/32" length under the head the price can tripple. So stick to the eights...

Thank you very much guys! Your kind comments are much appreciated, and it fuels my ambition. This is truly an amazing forum, one of a kind. When it comes to model engineering not everybody gets it, but here, all is shared amongst people who do. The help received here is priceless, I can safely...

George, In response to your great writeup on model ignition systems. What can I do with the gap on the spark plug? I have it at its max of 25 thou, which is only slightly more, a few thou, than the side of the ground strap, and un-coincidently the same as Gail is using on his Tiny IC. I...

Iv'e been waiting a long time to post a thread in this section, and am proud to say I have finished the TI4. Here are the pics. Kel

I know you already accomplished this, but I though I would share the method I use for rounded bolts. I take a dremel cut off wheel and cut a slot in the top of the head, for a flat screwdriver, then proceed to remove the bolt with a screwdriver. pretty simple, though you would need a big...
