hey guys, i posted a while back, near the end of june. we had some trouble with my kyosho mp 7.5 sport. heres a link to the post.
we couldnt figure it out. when ever it did start, it would die. so we left it at a local hobbie shop, debbies r/c world. they said there was a problem with the clutch and there was a lack of compression. they installed a new clutch, and instead of payin big $$ for a new piston and sleeve, we shipped it out to Ray A racing, and he refurbished it for cheap. it now has good compression, a good clutch, so the engine was in pretty much new shape. we were tryin to break it in, with the factory settings, and it starts 1st pull, but as soon as u barely touch the throttle. it dies. every now and then, it runs for a little while, and dies. were not goin full throttle, because its still the 1st tank of break in. we installed everything right, the piston and sleeve is right, th4e glow plug is good, and everything else os on the money. we just cant figure out what is wrong with it. i you guys know anything that can help, please, it would be greatly appreciated.
