Intake Plenum Sunstar 20?

Recommended Posts


I cant find an intake plenum listed anywhere for my model number of 1691381? It is listed for other model sunstar 20's, but nothing for mine. I bought it without one as well. Anyone know?

Thanks everyone, I am glad to be here. Just bought this tractor and already love it, but it needs work. Has 730 hours on it. When I tore into it to lube everything I noticed it leaking fluid at the seal for the main output shaft at the hydro/driveshaft, yolk at hydro side seems a bit worn (1/16" play against the splines) and the U-joint at the engine side of the driveshaft has its zerk fitting busted off. Everything else works well, minus the money I need to spend to replace the missing plenum. Does everyone run one, does pointing the intake toward the battery suffice (I assume it doesn't).

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
