finally i start putting together my parts and ideas, and turn on the lathe and mill and got some good results,this is the engine for the 1/5 scale buggy or rail project that i been so long delaying.

the engine is a hybrid,is basicly a g62 with a redmax(komatsu zenoah) chainsaw crank,the flywheel is from a g230pum also the coil(red coil).the carb is a sthil chainsaw HD5 walbro 16mm bore,made my own high compresion billet head with decomp valve and made my own copper gasket out of .018 copper sheet.planing to install a nology discharge coil and use also the nology hot wire.the engine is not done yet,i just like to share to have some r/c gearheads comenting.

i read in some of the threads that the g62 is heavy...that power to weight ratio...non of those engines are ported...ect,with this tread i will try to get to those issues and see if i can make this engine lighter,high rever,and high p/w ratio...will see now to download some pics.:)

id have no idea, your past my level of experience LOL.

best thing to do is sit down with what you have, bolt it together and turn it by hand, if it turns smooth check some fuel in and try it out.
 
thats awesome...im not a pro engine builder,i just want to shear and see the diferent peoples reactions...thanks, i like the "sit down and crank it by hand"
 
Biggest rule of thumb (and you probably already know this), but you have to keep things balanced, and in an engine that turns roughly 20,000 RPM's, the least bit off balance and it will shake itself apart.
 
i been doing some porting,exhaust @92 degrees and transfer ports match @ 118 degrees (all those numbers are taken from top dead center and i base them on a cylinder and piston combo that i got from HB Hanson,at that time he claim 4hp or more on a 23cc with the right pipe,the kit came with a lighten piston maching exhaust,transfer port,and the base of the cylinder,to increase compresion),intake i left alone just make it a little wider.and made the insulater hole a bite bigger to fit the hd5 carb :)
right now i going to focus on finishing all the little details to get it running for all to enjoy...;)
 
forgive the long absence,between job search and search for a platform to put my motor neglect my project, I hope they are still awaiting the results, as has happened a lot since then, new high power OBR singles to the 50cc BZM. it's exciting to see so many new things in this hobby, well I leave you with these words.
