1948 C low on power

I recently rebuilt the motor on my C. New piston and sleeve kit. Used my head from my 140 along with the manifold and carb. It runs fine. Sounds great but still powers out when all the other c 's don't. Is it possible the governor isn't advancing the throttle enough under load?
 
(quoted from post at 13:50:15 09/08/14) Do you have the throttle set to specs. Did you set it adjusting clevis with engine off ect.

Could you explain the process to set that? Thanks.
 
You put new pistons and sleeve in it did you use oversize pistons and sleeves? If you did did you reset the timing for the new pistons and sleeve kit?
 
If the engine is running "wide open" RPMs under load, then the governor is working fine.

How much breakin time has the engine had? Fresh engines will get stronger as they break in.
 
It's been to four tractor pulls pulling 3500 and 4500 class. Plus some random driving. Probably over 20 hours running time.
 
with your engine off,take out the pin on your adjusting clevis.its the clevis on the rod that connects to your carb.now back out the screw behind your carb.now pull the throttle all the way open.your governor rod and your carb rod work together,so push your carb rod all the way open=push it all the way to the left.now take the governor rod and pull it all the way to the left.you want to adjust the clevis so that both rods line up to each other and the pin will slide right in to each other firmly.now start tractor.they should work together.adjust your rev screw behind the carb to where you like it.
 
sorry,after reading what I wrote I see I made a mistake..when adjusting the two rods,the carb rod wants to be pushed all the way to the right.i said the left.the right will give max carb load. start over,it should only take 5 minutes to do this.
