Originally posted by sastanley View PostSteve, exactly the opposite. Higher octane fuel burns slower, and is designed for high compression engines. At only 6.3:1 compression ratio, a lower octane fuel will perform better in the A-4. What is really missing from modern fuels is the lead that lubricated the valve stems/guides, which I believe is one reason MMI recommends some MMO in the fuel to account for that shortcoming of unleaded gas.
TRUE GRIT

What he said was, “I have never had a carbureted engine, with spark, fuel, and starting fluid, fail to cough, sputter, or make any indication of fire in the cylinder.”
So he HAS had carbureted engines. Therefore, you must not be getting old.
(Are you buying it?)

I think you're starving for gas, not flooded. I messed with the adjustment screw a little. I think it just makes the engine run hotter and burn more fuel. I couldn't even get a flame to shoot out, just black smoke. Stop using starting fluid. You'll break the chunks of metal in between the piston rings or snap a rod

Steve, if you can get carb'd motorcycles to run, this engine should be similar, and also can be susceptible to the same problems as motorcycles that don't run often (stale gas, gum/varnish in carbs, etc.)
My last carbureted car was an '85 Civic, which gave up the ghost about 1994. If I recall I got $1000 or so for it on trade-in.Last edited by sastanley; 11-29-2017, 11:42 PM.-Shawn
