Basics first. Do a compression test, spark test ( should jump a 1/4 " open air gap ) and then get into the carb repair and ect.

Is this motor worth repairing. I Have the time but do not want to throw away money on motor that is not worth repairing

As mentioned, check compression first. If it has good compression, most everything else can be addressed with a little time and probably less than $150 in parts.

Compression 92-93 This is on low end?

Sounds okay for the age of the mtr.

Roger, try too keep all of your questions regarding this particular motor on one thread. It will be a lot easier for future readers to follow your progress. The compression is fine, which only leaves spark and fuel. You should be able to get a bright blue spark capable of jumping a 1/4" gap. A spark plug gap tester can be had for about $5 at the auto store. If you have weak, or inconsistent spark you'll need to pull the flywheel and inspect the ignition. If you have good spark all that remains is fuel, in which case you probably need to rebuild the carb. Use the links we've provided in your other threads to walk you through the job.

Thanks for all the info. Spark is good Checke with Checker I purchased. I ordered The carb Kit and float the other day and will work on it when Parts arrive. I am Hoping to have some pics for this Motor when I do the Carb cleaning and Float replacement. Sorry I am New to this site and Its been a Great Help. I have One other Thread out there on the Throttle linkage but No real help yet.

No problemo. I posted a response to the linkage post. There should really only be one or two linkages along with the 2 nuts that hold the carb on the powerhead. Once they're removed, the carb should come right off so it can be cleaned/rebuilt.

Thanks for the help. I will be working on this Carb Sunday. Parts arrived today. Would like to get this Motor Back to Speed. Golf is in my schedule for the next four days. I will Take some Pics of the Process Removal and cleaning. My wife will help I hope with The pics.
