Hows the carburetor ? Sounds like you might be running lean....which causes high heat in the motor

I couldn't tell you how the carb is. I'm sure it needs good cleaning and possibly rebuild. It's a edelbrock 650cfm was what I was told. There is a difference in the fuel system since it's been driven last on the road. It originally went off the road due to the fuel pump went and 'ignorance kept me with the cheap advance auto mechanical pumps that didn't reach the cam I assume since out of quite a few none worked' I finally heard about and installed one of the $45 universal electric pumps from advance. Around the block or neighborhood it didn't give me any problems getting on it or not. At the time it was open headers and no brakes so didn't go far or too fast. But that is one thing I'm coinciding to be a culprit until I prove otherwise. . that and the routing of the fuel line. With the new headers full length dynomax (got a great deal on them) I had to re route the fuel line behind the motor. Which leaves the fuel line going up at a steep drive. Which before I had it going to the front of the motor towards the mechanical pump them gradually going up and around the motor. Imade a point not to mess with the timing and the carb adjustments since they are untouched from when it used to drive with no issues. Someone told me the jets in the carb could be clogged. I am completely unfamiliar with this carb. sinceonly messed with one barrels in a old ranger 4 cyl. And cleaned the 2 barrel. I just keep pointing towards vacuume since I've rigged one and it ran 100% and stayed at a normal temp. There isn't a thermostat in there until this weekend. If there is it's stuck open or partially open. I know im also replacing all the vac hoses that I can this weekend also since they are old and I currently have a fuel line on the main on the back of the intake manifold. Which when I did that it idle at 750. No misses, ran at normal temp and stayed there. Only catch is it ran so good I decided to see what it can do. Soon as I passed the jetta and let off at roughly 75-80 . no speedo yet. It backfired as I let off and barely got back home. Hadn't ran good since. It may very well be the carb or at least fueidling gauge I have in the back by the pump shows between 4 and 5psi at idle depending on how long it's been. Maybe I can get a extra set of eyes on it this week to see what it does under rpms. Either way that's at the rear though. I remember it smelled alote richer before when I drive it or just moved it around the yard or around the block. I can still smell fuel but if the hoods open and I'm near the carb. Not like flooded smell just can smell it there

Sorry for the book and bad autocorrect. Impatience has got to me. I'm not thinking things through like I should be and taking too many shortcuts. I need to do all the vac hoses and double check routing. Ive had better luck in the past with no vac hoses except for the vac advance. If and probly will be still a problem I need to look at what's different from before and what's dirtier and go from there. It's probably a good idea to rebuild the carb this weekend too or at the very least clean it out really good. Then if there's still s problem I'd bet it has something to do with the fuel pump ot the routing

That carb may need a rebuild...around here Autozone has the rebuild kits in stock. I ran an edelbrock 650 for about 5yrs on a stock mustang...I didn't have to adjust anything but the front two idle mixture screws and the lever at the top (power valve). An air fuel ratio guage came in handy from autometer. Its good to know how the fuel is burning anyway. I used to get 26 mpg.... Amazing right.lol. that's cruising at about 70mph.

Wow, it crappy mpg. Back when I drive it years ago (granted back then I thought every red light was a drag strip and getting pulled over for showing down to 115 in a 45) I wasn't get prime mpg. I measured out to 5mpg city. Won't run any better then it is now on 87 either. . No crazy mods either. I'm hoping to get 10+now that I'm older and drive more responsible. Its only mods that I was told it had when I got it and that I've seen is. Edelbrock torker 2 manifold, the carb, solid rockers, exhaust, supper coil, and stage 2 clutch and a mild cam. And a slightly different'shorter shifter' matching numbers everything

If love to get 26mpg out of it. That would make it alote more I could drive it... I have done the math though. About 45 minutes of idle/around the house run time is a gallon of gas

Now just for confirmation since I got it from a friend years ago that isn't a gear head. How would I know for sure it's the 650cfm?

I haven't heard of power valve problems with Edelbrock carbs, but some the Holley carbs have problems with the power valve. A backfire on some Holley carbs can damage the power valve, causing it to leak fuel into the intake any time the engine is running. This causes fuel economy problems and rough running.

For now I'm going to hope there isn't any damage to the carb or the power valve. I've seen rebuild kits in a part store around me, think the local auto zone. I'll look into that this weekend. At the very least. It has been backfiring through the carb and mainly in the exhaust. I saw in another thread about the ignition and the starter soliniod. I'm sure that the ignition switch is original. I replaced the starter solinoida few years back. Ifi recall the first one I got didn't work and I had to s swap it again. Is that a possible factor when it's this bad off?

I just got back from a short drive running a couple errands I couldn't do by bike in the rain. Little iffy getting it started originally and idled. Usually a child start it fires right up. Other then that it drive beautiful. No misses, didn't die but once when the motor was still cool. My only problem was seeing through the windshield lol. Old dry rotted wipers made it worse. Just took it slow. Only one rain burnout at low rpm. Didn't get on it at all. I'm aiming more and more to it being the carb needing a good cleaning or a rebuild. The 2 main barrels I guess it's pretty good but when the other 2 get used it's clogging the jets and messing everything up to where it's acting like misfire

Update for those of you helping with the problem. It seems to be the carb Is dirty. My buddy told me a cheat to clean it for now. Spraying some carb cleaner down the carb while it's running. Tried that along with some seafoam in the gas tank and took it for a test drive and alote better. Even got on it just through 1st and half of 2nd and let off and it backfired about 3 times then evened itself out back to normal. Alote better. I cleaned it some more since but duei temperatures I have to let it sit some before continuing and testing. Temp while driving wasn't too bad. Warmed up a little bit near the end of the ride. To the m in normal. Slowly getting warm. You were right with bringing that up. Thank you for your advice

And yes it was running lean. Now can smell it running rich again for sure. Granted the seafoam and carb cleaner are helping with the rich smell at the moment.

Thank you very much. Im at Walmart right now. Maybe a20 minute ride from the house. It ran beautiful the whole way here. Think the carb is good. I just hope the thermostat is why it's overheating now. Only problem left I believe. Was hoping that was associated with the rough running. It rose slow and motor was warm already. Kinda acting like that's it
