I have an MS290 that is giving me trouble.
Last year it stopped running so I
1. Put a carb kit in it
2. replaced the fuel filter
3. replaced the fuel line
4 replaced the spark plug
It ran good after this work
Now, it starts easy and runs strong for about ten minutes. Then it starts to bog on accelleration and does not want to idle. A few minutes later, the RPM at full throttle begins to surge up and down. After that, give it up because no new work will be accomplished.
I just cleaned the air filter and retuned the carb. It fired right up and repeated the above problems. I tune as follows:
1. H and L one turn out
2. LA up until it wants to crab the clutch
3. L in until it starts to die then back one half turn
4. H out until it starts to burble pretty good at full throttle
Any suggestions
