Appreciate the series on the Blackmax! Gramps has the exact same that has been sitting 10+ years and your videos helped build the confidence level to get a new project rolling 🎉

Sounds like a great project- would love to see a "will it start?" video on that one!

I have a vintage 70's Merc Thunderbolt 50HP 2 stroke 4 cylinder that I rebuilt and got running, but it idles very high in neutral!. Anyone know what I need to adjust to get it to idle like this one does in neutral?. I was thinking it could maybe be the cable that comes from the Mercontrol/throttle and choke, and maybe I need to adjust one of the stop screws on the side?, and I know one does timing so I just need to know which one to adjust so I don't accidentally end up screwing up the timing!?. Any advice would be very much appreciated!. I want to go on the water, but I can't because I know if I put it in gear with it idling that high that it'll be bad news bear! lol

Thank you for this video. Is that red annodized part in the fuel system a check valve?

It’s an add on fuel filter, installed by the previous owner.

@ProWrenching quick questjon how do you test the enricher valve? I've also disconnected mine and can't remember how it goes back on I assume the black is ground to the block and black/yellow is power.

@ProWrenching 7 ай бұрын

@@shitboxoffroad you should hear a click noise when you push in the key/choke on the throttle. When the key is pushed in, it applies voltage to the yellow and black wire, and the enrichener valve should click and open, allowing fuel to pass thru the valve. Yes, black is ground, black/yellow is power.

Dumb question but turning in, "tightening" the screw turns up the idle correct?

I jave an issue with my 175. I have took carbs apart. Adjusted the floats. Changed one of them. But i have to kep the throttle shifter forward so it will stay running. If i pull it back too far or in the actual nutrual position it will stall out. Almost sounds like it wants to back fire. But it stalls and pushes gas out if the overflow tube. If thats what the tube is. Too much gas? Or not butning it off. It does idle good and sound good idled up. It eill take the fas then. Do you have a video that will help me??

If your carburetor is overflowing when idling , I recommend rechecking the float adjustment. Also check your fuel lines to make sure that you don’t have a leak.
