QUESTION: Blower,Barbuda32cc
Newgasline,spark,starts oonfirstpull when pouring smallamount of fuel in carb runs strong 3-5secyu

Answer
If it starts on prime (pouring fuel in carb) then odds are the compression is fine.

Why did you replace the fuel line?  Was is hard, brittle and cracking?

If so, the carburetor diaphragm is made out of similar materials.  When the metering (carb) diaphragm get hard it will prevent the carb from working.

Did you inspect the carb metering diaphragm?

Lots of videos on You Tube on rebuilding blower, string trimmer and chainsaw carbs.  Easy to do and parts are cheap if you know where to look.
