84 FL250 help?

[Wheresk24z7]

Hey group, new here. Greetings from CO, I just recently picked up an 84 FL250... Working on getting it running but wont start, ive gone through the carb. Cleaned out the fuel tank, replaced the broken ignition coil with a new one, new spark plugs (BR9ES)... It had started and ran for 30 seconds before it cut out and now wont start, only idea i have is electrical issue? any help would be appreciated. (1984 FL250 with original engine, gravity feed fuel system to carb(aftermarket Mikuni)

Check compression with a gauge. The pull start spool is really small. They pull hard so that is not an indication of high enough compression. An air leak test would be nice, but it does require taking things apart. So visually inspect for possible air leaks like the tube that goes from the crank case to the fuel pump. If cracked/missing, it will suck a lot of air. You say gravity feed so it would need to be plugged off. If you do get it started again, you can spray carb cleaner around seals and gaskets to check for leaks.

  The fuel pump was removed and it uses a gravity feed system into a mikuni carb made for gravfeed, what stuff would i need to rebuild the top end if the compression is low?

Was the port on the crank case that ran the fuel pump plugged off?

For a rebuild: You would need a piston kit, likely one size larger than current and a gasket kit. You would have the cylinder bored and honed to the new piston. You might want to put in crank seals if age is unknown. With seals removed, play in the bearings is easier to detect. Replace if there is.

  The crankcase vent for the fuel pump is plugged off, and ill see how the compression is, how much PSI should it be?

Not sure off hand. Shop manual: https://drive.google.com/file/d/0B851Fdu_42hLa2xfaFZQWmdTcmFrMTF2STFNYkdpZw/view?resourcekey=0-ZoYcv0cF3ALCbpNCnJwcyw

Update: Compression reads 130 PSI, i believe the issue is spark… any clue how to fix the points systems? Thanks

I have cleaned points on other engine by opening and putting a dollar bill in the pulling out with them closed. Point gap specs are listed in the service manual linked above on page 8-10

Doing a search on this forum for points, I found this post listing ignition stator winding and pulse pickup at 240 ohm and 38 ohm: https://www.odysseypilot.com/index.php/topic,44388.msg155528.html
I don't know where he got those numbers or if that is what his machine is, but he seemed to indicate that was in spec. I would also check for loose wires, etc.

I looked at the points system, not sure how it works. the manual didnt do much other than a brief picture.
