No Fire

[250rcrzy]

I have a atc 90 year 76. The problem I am having is that it will not start by pulling the pullstarter. The only way to get it to fire is buy pull starting.
The timing is set, I have spark when i ground the plug out on the head and use the pullstarter. Does anybody have any suggestions. :?

If you have spark you have fire. Points more to a fuel problem to me.

Has the bike been sitting long? If it has, the carb will need a little TLC i.e., a good cleaning with a new rebuild kit to boot.

Have you checked the compression? IF the rings are wore down and you have low compression it will make it hard to start.
