I have an update to this machine as I started tinkering with it yesterday. The motor is actually something like a 61100 Briggs and stratton and that generally gives me an idea of where to go from there. I still have no REAL model number stamped anywhere. It is just crazy.
Well, I kept getting odd back pressure through the carb. I removed the carb and those old suction carbs are truly a pain but with few moving parts you can work with them. It was pretty rusted and clogged.
I removed all I could from it and cleaned all the passages. The carb still has rust down the throat of it. Maybe later I will run my .22 barrel cleaning brush down it to get it REALLY clean.
Well on to the real problem. I shot some carb cleaner down the carb hole while I had it off. Pulled the cord and found that I had spilled some of that fairly liberally around the engine. fire shot out the hole and ignited the spillage but it was not that hard to get out. lol lol
This made me remove the valve cover. Yep, here was the problem. The intake valve was stuck open. It was pretty good and stuck too. I removed the head and yes it was open and not coming down---until I tapped it with my ball peen and squirted liberal amounts of liquid wrench type product down it. So it was rotate the engine and get the valve to go down about ten or fifteen times until I got it good and loose again. I buttoned that all back up again after cleaning the head and valves with a brass brush and rinsing and drying it. The bore looks brand new---no scoring at all---amazing considering the age.
I moved on to pull the flywheel. The recoil needed some oil anyway so off it came and got my mix of trans oil and regular oil. Works good now. Pulled the clutch and oiled it too. The flywheel came off easily. The condenser and points were all corroded and yet they were still delivering a spark when I tested it earlier. I Use some contact cleaner and the brass brush again to clean it all up and make it serviceable again. I also dressed the points.
When I put the car back on the tank I knew this was not going to end well as the damned fuel pick up tube had a crack that ran nearly all the way down it..... I figured just filling the tank good would help---yeah right......
Anyway, I buttoned everything up and tried to start it. It ran with whatever I put in the carb but that was it. The carb is just not drawing from the tank with that cracked tube. However, I can say---IT RUNS!
So on to try to figure how I was going to fix it. Well JB Weld seemed like the answer but then I actually found the part number for the tube during further research (293700). Unbelievably, there are tons of them on eBay for about $11---NOS! So I have a new on coming but that leads me to the end question---how the heck do I get the old one off? That thing appears to be on there REALLY solidly..... I guess I could get out the vice grips and have a go at it but anyone had a way that seems less neanderthal and less likely to damage the whole carb?
Regards to all,
