i have an 2010 honda enging 670cc el diablo truckmount i wanted to know what rpms should it be at full throttle and what should the rpms be at on load at 15 hg. im running the trottle open at 3600 rpms and on load it will drop all the way down 2900.
it doesnt bog down just seems like the engine is trying so hard. ive checked compression on the engine reading at 160 on both sides changed spark plugs new carburetor new kunkle valve changed fuel filter and air filer on carb . i feel like the kunkle valve opens up to early also.
