Why Wont You Start!!

Hi All,

I'm tyring to get my 1971 Rupp Sprint34 going. I've spent the last month working on getting spark. I now have spark, fuel is going into the cylinders, the exhaust has been cleaned out...but I still can't get anything more then a sputter.

This is a link to a video of its best sputtering!

Thanks Dave, I will give new plugs a try and see if that does anything.

Any luck?

What plugs are you using. Stay away from the resister type plugs. Have you tried spraying fuel in the carb to keep it running?

No luck yet! I think I've narrowed it down to timing. When I got the machine, it looked like someone had been playing with it so its been a slow process! I'm looking for a day to do nothing but little adjustments to its timing and see where I get! Now that the snow is melting I'm not in as big of a rush!
