I have a NEW HB 61 Engine w/ perry carb that we've had in a box for years. It's in Perfect shape so we thought... Having LOTS of trouble keeping it running. The engine will start sputter and then die.. I read the posts regarding adjustments of the HIgh Speed needle and low, and have tried that.. I've finally put a 4 cycle plug in and it now runs.. the problem ?? It gets HOT.. It will only run with the needle 1 turn out.. very lean.. Then of course will over heat and die.. 2-3 turns it it barely runs, sometimes doesnt start.. I've changed the tank, checked for air leaks in the line, replaced the carb w/ another Perry carb I had on another HB 61 no luck..
At least now I can get it to run, but it runs lean and will eventually die.. If you richen it up, it will not run well nor will you get full power.. In fact full throttle will just eventually sputter and die.. ANY Help I can get would be appreciated.. Ive had nothing but trouble with this engine, yet it's practically brand new.. with the exception of the 4-5 tanks run through trying to get it to be nice..
Thank you!
