Im rebuilding a 730D. Is there a way to adjust the fuel. (turn it up) These 2 cylinders are new to me and just trying to figure some things out. Any info that the manuals don't tell me would be great. Any hints about additional power would be greatly appreciated. Thanks

Get more airflow from a cam,over size intake valves with a nailhead back cut, three angle valve job, blend the valve bowl rough edges, low restriction dry aircleaner conversion, dual exhaust if legal. 830 tips with the stock 13mm pumps. Place on a dyno and add fuel until HP is almost peaked. Then again the local winner or at least places in the top three of the 10,000 classes has a bone stock 720 rowcrop. Puts her in 1st and lets the GoodYear Traction Torques dig in. Perfect balance and max traction at the end of the track beats the souped tractor stuck at mid track.

There are talented honest folks out there who you can ship your pumps, injectors and transfer pump to. They will overhaul everything and calibrate the system to meet your needs. I did that 10 years ago with my 730D and never regretted it. It doesn't need to cost an arm and leg, either.
