i have a 87 champ that i replaced a bent intake valve in and now i got good spark compression and even using starting fluid it wont start please help

 

That one is similar to one of mine,... A slightly slow starter will not turn it fast enough to git 'er runnin'. Use some jumper cables and do a one time start and see if that helps.

If not, it may be time to check the valves again. They're kinda hard to set while the engine is installed, but it can be done. I suspect you already set them on the new valve install, but check them once more and varify timing if the jump start won't do it.
