I-544 Motor Problems, Banging sound

Posted by Don on March 25, 2002 at 07:15:44 from (64.105.216.218):

I am in the process of trying to get my Grandfathers I-544 gas tractor started. I finially got it to run for about 1 minute then it stalled and would not restart.

I am having a mechanical banging sound in my #1 cylinder. With the spark plug out the sound is not present and I am getting air out of the spark plug hole. When I insert the plug, I hear what sounds like two pieces of metel hitting each other once every cycle. I cut the tip off of a old plug and inserted it, and still got the sound. From this I am assuming that the spark plug is not hitting.

All I can figure is that under compression one of my valves (I think exaust) has a week spring and it is getting slammed up into its seat. I would think if the valve was broken it would be hitting all the time, not just when under compression.

Has anyone had this problem, or is my logic faulty? Before I tear my engin appart looking for this problem I thought I would ask. It isn't supposed to make this sound when it is running is it?

When the tractor would stall, it would spit fuel out the carb (air tube off). I was thinking that if the exaust valve was not staying open (pressure would build under the exuast stroke), when the intake opened, the pressure would push the fuel out the carb instead of drawing it in.

Also if this is indeed the problem, how hard it it to fix a spring with the head bolted to the engin.

Sorry for the long post. Wanted to list all the details. Any help would be greatly apprechated. Also thank for all the help everyone has already giving me on this tractor in other post.
