So I just got what I thought was a sweet deal on a motor. A box of knives (value of about 6.5 bucks) for a 19** Sea King motor vw8 52179C. ** is because I cannot find what year it is. I think it is a 79 or 80 but not sure.
It runs for about a minute after having to spray a bit of starter fluid in it but then soon dies after. It will not start without it but however I know that the fluid burns up pretty quick so it should be running on gas for the most part for that minute.
I thought that there was a place here that I could find this out?
It will start but not run for a long time. I can see an Idle screw and one screw on the carb (not 2) so what would be a good adjustment for this?
I am sure that the oil that should be put in this is TCW3 but if I do not use that type of oil will it run good or do as described?
Sorry if I have gone over my question limit and I am sure I will have more. Thanks for the help.
Sounds like a carb kit or carb adjustment is needed.
Quick replied to question with no harm intended:
1. You can search this site for info but a manual would be your best source for info.
2. I would disassemble the carb and fuel pump (if separate) looking bad diaphragm, varnish from old gas, checking all ports with all screws seats removed using fine wire, carb cleaner, soak if needed, compressed air if needed. One turn from seat, might be a good starting point with the adjustment.
3. Use the correct oil and ratio to prime/start or you could damage the cylinder. Correct oil is probably not the problem vs fuel supply.
Good Luck And You Sound Close To Running But Correct Is The Goal! jow
PS. Bottom Line! There Are No Instant Answers W/O Researching!!
according to the numbers you have listed 52179c that comes up as a 1982. on the left side of the carb there should be an adjustment screw and spring, that is for the idle mixture. it will have nothing to do with the operation at high speeds.the correct setting is one turn out for the idle screw. the jets are your high speed jets and are interchangable according to altitude to sea level 4 jets were made for that style carb. this problem you are having could be the fuel pump which is a diaphragm style or a dirty carb. if your careful you should be able to remove it, disassemble and soak overnight in two stroke mix. clean all parts completly and reassemble. you may need to do the same to the fuel pump as well replace parts that are worn or coroded.hope this gets you going in the right direction.
the diaphragm type fuel pump is mounted on the side of the cylinder block and ported to the upper crankcase. pressure and vacuum pulsations from the crankcase are directed through port to the rear of diaphragm. when the power head piston moves upward in its cylinder, vacuum in the crankcase draws the diaphragm inward and fuel enters the pump through filter and the inlet reed valve in reed plate. when the piston moves down in cylinder, crankcase pressure increases and the fuelpump diaphragm is forced outward into fuel chamber, and fuel passes through the outlet reed valve into the carbuerator line. defective or questionable parts should be replaced. pump valves should seat lightly and squarely on reed plate. diaphragm should be replaced if air leaks or cracks are found, or if deterioration is evident. also the reed petals could be suspect, if they are cracked broken or bent they will need to be replaced. to answer your question about blowing your cheeks off if it is in the closed position you will then blow your cheeks off, but if the diaphragm is not flucuating properly then it will never allow fuel to pass through.i have examined many diaphragms and they all look fine if no deterioration is evident but they still fail over time and from sitting idle,storage, drying out.i hope i gave you somewhere to look. is it possible to disconnect fuel line from the pump to inlet of carb to see if your getting a good fuel flow?

your welcome hope you can figure it out without spending too much money. i got lucky and was able to find the parts i needed to rebuild my fuel pump, they arrived today and i hope to be on water to test it out on sunday. best of luck to you
