I have a dynamite 053 pipe
What can this be? The engine is about 2 gallons old
tried the settings griz posted but it still does the same, no air leak, new odonell 097 plug
If I cant fix this I will be breaking in the 3 port
What pipe will be good for this 086 or the 053?
what are the best settings for this motor?
Thanks
You have a Lean HSN that is why its bogging after a few mins , Try leaning the LSN a little , lower your idle a little and richen the HSN 2/8
Put a fresh plug in and see how it goes.
BTW Stock settings are FLUSH HSN AND LSN . The ONLY way to come to a good tune is not to try a recommended set of turns in because every engine fuel pipe tyre set up will require a different tune.
So if you are in doubt reset to flush HSN and LSN then start to tune form the LSN first .
