FD851D Engine Map 1 and Map 2 switches

I am upgrading my '84 Scag Turf Tiger from a Kawasaki FD750D Carbureted engine to the fuel injected FD851D engine. I routed the return fuel line back into the tank, and I think I've worked out the wiring from the old harness to the plug on the new engine, but I can't find anyone anyplace to tell me ..

FS730V Backfire under load

I'm kind of stuck right now, I have a Kubota z421 with the FS730V with 192 hrs. Everything was running smooth until about 4 months ago, when the engine began to backfire whenever the blades were engaged (as soon as the PTO was disengaged, the backfiring stopped). I will add that the mower was left o..

FR651V Carb choke plate

How does the choke plate attach to the choke lever? Mine came loose and blocked the throat of the carb. I removed it to finish my day's work, but would like to repair the problem. In the diagrams I'm seeing there are no screws, and there are no holes in the lever for a screw to go into.I don't want ..

New FD750D on Lazer Z wont fire up

Hi, I decided to swap out my old FD750D-BS03 with a new FD750D-S03 on my mower since it was not charging and the motor was 22 year old. The old motor was running fine but it kept draining the battery since the regulator was not charging the battery. I removed the old and installed the new motor, now..

Drive shaft

New to this forum. I did an engine swap on my Hustler 60” zero turn powered by a Kawasaki FR730V.

My question to this foru..
