I have a 35 horse chrysler and i keep fouling the same plug every couple of trips 2 the lake . I checked compression one cylindar read 100 psi the other was about 105 . It burns through the gas also, I would say it burns 4 gallons of gas n about 8 miles . Any suggestions ?

If you haven't rebuilt the carb and fuel pump in a while, it is always a good idea. I also suggest that you swap the coils and see if it moves. You could have a coil going bad.

Re: spark plug fouling

any chance the choke could be hanging slightly closed? This would explain some of your problems that you have ,and very easy to check for this condition. just my two cents worth. MOPARMAN
