i have 1980 rx7 87000miles . i live in ny & the weather is cold now .what should i do to when starting as it takes awhile to start

 

Pump the gas and choke it?

 

Don't pump the gas, it will flood. Depending on how well your carb is working, you should just pull the choke, wait 10 seconds for the pump to run and fill the bowls, then crank it. It may take longer to start due to being cold. Do not turn off until the choke pulls in or the temperature is at operating levels. Again, turning off a cold rotary is a prescription for flooding.

 

thankyou

Been starting mine by pumping the gas 3-4 times for literally decades without issue or flooding it.

I didn't mean to continually pump it. Just 3-4 then choke, start. A few pumps isn't enough to flood it unless something is wrong.

 

Same as any carbureted car - pull the choke the whole way. Pump the gas a few times (varies car-to-car, I do 4 or 5, depending how cold) and crank. It'll either start up or hit a few times then just crank. If it hits and doesn't start, give it a couple more pumps of the gas and try again. Ideally when it hits, you'll give it gas again to get it going. The idea is that when you hit the gas, the accelerator pump in the carb will shoot fuel into the engine, which is what it needs to get started (especially when cold). You'll get a feel for it. If the choke plate is removed, it will be considerably more difficult once it's below a certain temperature (but still possible).

 

Whatever works for you, I was just relaying my own personal experience based on owning and driving my 7 in very cold climates for 20+ years.

 

Not quite, these cars flood easily because when gas is supplied on the initial start and it fails, depending on the amount of gas pumped, it may wash away the residual oil that is providing the seal to make compression. Once that happens, it will not make good compression and adding more gas will just make it worse and be flooded. If initial start fails, don't pump more gas but just try to start it again. You may have to squirt some oil into the carb throat to regain compression.

 

When mine was a stock 12A, I pumped twice and pulled the choke and it started every time. That was after I replaced the charcoal canister that had 300K on it. Before that it was a crap shoot.
