Hi all, hope you can help
All the time I have had this engine it's fine at tick over but as you rev up just as it get up on the plain it coughs and splutters a bit but once it up it fine. Revs round to 5.5k no problem.
End of last year all of a sudden the tick over got bad and it died, started Miss firing and wouldn't run.
since then I have.
replaced spark plugs, had the carbs sonic cleaned twice. Still running bad so then replaced all the fuel lines and filters still running bad but I noticed that if I pumped the bulb it run ok for a while but there was obviously an air leak somewhere so replaced the diaphragm in the fuel pumps and now it runs well on tick over but as I rev up it coughs and splutters and won't allow full revs. I would guess only revs to about 4K maximum after a fight.
All this is on the trailer, not under load. Has fresh fuel, new oil.
Not sure what to try next but run out of ideas, please help !!!!
regards.
