Hi there,
I have been reading all the posts on this type of topic and everyone v says fuel/carb, but I don't think that is the problem.
I have had my engine for 4 years without issue. It always starts first or second pull. The carb was never cleaned, nearly never run out of fuel, but like I said, never any problem.
The issues started 3 weeks ago running the motor on my sailboat 3. In the middle of the day, the engine would want to die anywhere near idle. This was totally new. Later we ran the motor wot as usual with any further issue, but the oil pressure light was coming on sporadically. The next day I changed the oil but I apparently filled it way too full. It was dark out when I filled it so I couldn't see the oil line on the dipstick I guess.
I tried to start it at that point but if course it wouldn't start with so much oil. After reading the forums, I thought maybe the carb was dirty so i cleaned it and put it back on the motor. No change, then I changed the oil again to the proper level and I went through the carb again. The engine would generally just sneeze but not fire. I adjusted the mix screw and still no change, although on the 50th pull sometimes it would start for a few seconds then die, but generally would just sneeze.
I checked compression; about 60 psi. I thought maybe spark so i looked for it during the day but of course could not see anything, but i could see the spark whe l i looked at night, I checked timing, it looked alright. I thougt maybe the electrical components are bad so tested the ignition coil which tested 5200 ohms instead of 4400 per the manual, but so did two other engines and i asked two shops and they both said they don't carry that part or ever change it so i don't know what to make of that.
I went through the carb again and adjusted the float level per the manual; 9 to 10 mm off the top of the carb bowl. All the Jets were clear. The carb bowl fills with gas .
The engine won't start even on starting fluid through the carb or in the plug hole even after 100 pulls It will fire "put put put" when the cord is being pulled but nothing else and it doesn't sneeze much but occasionally backfires a little or smokes through the carb.
The plug is a new ngk r as specified.
I don't know what else to do... can anybody help.?
