Hello!I just bought this 1980 for $500.It runs,but when the guy I got it from started it up it went to 4000 rpm and he gave up!So I took a chance,bought it,towed it home and found the problem.It was the hot start valve stuck open.I took the cable off and now it's only at 2000 rpm(he messed with the carb trying to fix it)but no worries,I'm slowly going threw it and reading my Haynes man.I'm 38 and this is my first rotary but I'm already learning alot from reading these forums and the more I learn the more I LOVE this car!
I can't wait to drive it.Anyway I just wanted to say hello.

Welcome to nopistons! You'll find that the carb is really easy to tune on the car. Start by correcting your idle by turning the idle screw in till she'll hold about 700 rpm. Once that's good then adjust your fuel mixture screw. Best way to do so is to use an a/f sensor and a gauge but if you don't have that you just have to play it by ear. You want it to be a little rich, but you don't want it to be so bad that it will bog down
Best of luck man and you may also want to download the first gen fsm from the first gen section here. That will help you find the proper vacuum line routing as it's commonly incorrect causing serious idle and run issues

May as well put a new water pump in while I'm at it,had to order that and I'm picking it up in the morning.I get that done and I can start tuning.I will be sure to take more pics with my phone tomarrow while I'm at it and post them so y'all can see what I'm starting with.

The guy went to replace the thermostat and broke one of the two bolts off,Can't get it out so I just got another used water pump housing so I can get my thermostate gasket to seal(it was leaking when I bought the car). The water pump housing holds the pump,thermostat and alt on top.I think the front cover you're talking about is the water pump.Anyway,I'm not going to put the old water pump back in when I put it all back together.bought a new one from autozone for $30. Funny I'm talking water pumps now cuz I just sold the last of my aircooled stuff and got out of vw's.here's some pictures of my last build,a 1965 beetle that was nothing but a shell when I started.
