I noticed the club close to you doesn't open for a while but it really would be worth it to just wait until you had some hands on help. Most of us would have those old engines running in no time if we had them in our shops. We have the items on hand that may be needed, simple things like heat guns and pumps to flush the carbs and know how to do it. As nasty as they look on the outside a lifter could be sticking or just a crud clog in the spray bar. I have a box of old and new glow plugs on hand for both two and four strokes, most of us do. I'm betting it's just something simple that someone in the know would spot right away.
If you know the name of the club you can look up the officers and give them a call to see if anyone in your area would help you out. I just got a call yesterday from a pilot new to the area and we are getting together so I can show him around to all the LHS and fields.
