Hello, I am new to this site and have no idea exactly what the procedures are so please have patience with me, I am also 70 years old.
I have a Kohler KT17 engine as mentioned it the title and am having lots of problems.
1st, I cannot locate an exact model and serial number as the B & S engines have stamped in the engine covers somewhere.
2nd, last year I was having problems getting it to start. So after checking compression realized one cylinder had low compression. The valve clearance was too tight, I reseated the valve, rechecked compression and it was still too tight so I ground off the end of the valve to get the correct clearance. The engine now had 105 # compression in both cylinders. It started good when cold or hot. Put it away for the winter but when I tried to start it in the summer I had no spark at the points or plugs. I had power to the positive side of the double 12 volt coil but nothing coming out the negative side and down to the points. The double coils are hard to find and very, very expensive. I called a shop that I frequent and he said they install a single 12 volt coil with a internal resister and just splice the plug wires together and it will work fine and it does. My problem is that it will not start. It pop's and backfires but never sounds like its going to start. I pulled the carb, (Walbro) disassembled it and cleaned out every hole I can find, all gaskets look good. Reassembled it, reattached it and it still pop's up thru the carb and backfires out the muffler. It sounds like it's out of time but it ran when I put it away for the winter and now sounds like it's out of time, how can the be?
Now to remove the flywheel it looks like the engine must be pulled because it's on the rear of the engine attached to the drive shaft. Is this all possible?
It seems like the plugs and points are firing correctly. When the piston on the left (sitting on the tractor) reaches TDC. on the compression stroke both the spark plug and the points spark together, isn't this the way it's supposed to be? If I spray gas or starter fluid in the carb it really pop's and backfires, seems out of time to me. What do you think? NEWBIE NEEDS HELP!!!!
