    I ended up cleaning the cap and rotor today. No luck on better operation. What’s your thought? Still the cap?

    5.7 GXI-A Hesitation and loss of WOT

    I ran down the entire tank to its current level. I topped it off about 3 weeks ago and then ran it all the way to 1/4 or so and filled it back up. Possible issue but I feel it's the timing because of how it sounds at idle (I'm far from a mechanic but she just doesn't purrrr like a kitten.)

    1977 Mercury Black Max 175 bogging out

    This definitely might be a stupid question but I’m having some trouble. So I purchased a 1977 charger with a 77 black max 175. It idles decent and won’t die at idle under load or in neutral. When I give it some love on the throttle it will sometimes get up to 2,000 RPMS (that’s full throttle...
